Half Moon Diamonds: Sophisticated Shapes for Personalized Creations
Half moon Cut Lab-Grown Diamonds
Half moon diamonds are captivating semi-circular gemstones that have been steadily gaining popularity in contemporary jewelry designs. With their unique silhouette—featuring one straight edge and one gracefully curved side—these elegant stones offer a distinctive alternative to traditional diamond cuts. At Labrilliante, we've seen growing interest in these versatile gems that can serve beautifully as sophisticated side stones or make a bold statement as centerpieces in their own right.
The half moon cut combines classical elegance with modern flair, making it increasingly sought after by those looking for something beyond conventional diamond shapes. Our lab-grown half moon diamonds provide the perfect balance of uniqueness and timeless appeal, allowing for truly personalized jewelry creations.
What is a Half Moon Diamond?
A half moon diamond, also known as a demilune or crescent-cut diamond, is a distinctive semi-circular shaped gemstone characterized by one straight edge and one curved side that forms an elegant arc. These unique stones are essentially half of an oval or round diamond, sliced along a single axis to create their signature semi-circular profile. At Labrilliante, our precision-cut half moon diamonds showcase the perfect balance between geometric precision and flowing curves.
The half moon cut emerged in the early 20th century primarily as an innovative solution for creating perfectly matched side stones. While originally developed to complement and enhance other diamond shapes in multi-stone settings, today's half moon diamonds have evolved beyond their supporting role. These versatile gems now feature in numerous contemporary designs, from classic three-stone engagement rings to avant-garde statement pieces that showcase their unique silhouette.
Though not as common as traditional cuts like round brilliant or princess, half moon diamonds offer a distinctive alternative for those seeking something truly unique while still maintaining the timeless elegance that diamonds are known for.
Key Features and Characteristics
Half moon diamonds possess several distinctive characteristics that set them apart from other diamond cuts. At Labrilliante, we carefully craft each of our lab-grown half moon diamonds to highlight their unique features:
Distinctive Silhouette: The instantly recognizable semi-circular shape creates a soft yet architectural presence that complements various jewelry settings. This geometric versatility allows half moon diamonds to work harmoniously with both angular and curved design elements.
Faceting Styles: Half moon diamonds typically feature one of two faceting patterns:
- Step-cut faceting: Similar to emerald cuts, with parallel facets that create a hall-of-mirrors effect and emphasize clarity
- Brilliant-cut faceting: Features triangular and kite-shaped facets that maximize light return and sparkle
Typical Applications: While traditionally used as side stones in three-stone engagement rings, half moon diamonds have evolved to serve multiple roles:
- Accent stones that frame and enhance larger center stones
- Matched pairs in symmetrical designs
- Stand-alone centerpieces in unconventional engagement rings
- Complementary elements in custom earrings and pendants
Symmetry Considerations: Perfect symmetry is crucial for half moon diamonds, especially when used in pairs. At Labrilliante, we pay meticulous attention to proportions to ensure our half moon diamonds are precisely matched when sold as pairs.
Bow-Tie Effect: Like many fancy-shaped diamonds, half moons may display a bow-tie effect—a dark area resembling a bow tie that appears when light doesn't properly reflect through the diamond. Our expert cutters at Labrilliante minimize this effect through precise cutting techniques.
Half Moon Diamond Faceting Styles
| Faceting Style | Light Performance | Visual Characteristics | Best For |
|---|---|---|---|
| Step-Cut | Flashes of light | Clean, architectural lines | Emphasizing clarity and color |
| Brilliant-Cut | Maximum sparkle | More scintillation | Maximizing brilliance and fire |
Pros and Cons of Half Moon Diamonds
Understanding both the advantages and limitations of half moon diamonds can help you determine if they're the right choice for your jewelry piece. At Labrilliante, we believe in providing comprehensive information to help you make informed decisions.
Pros:
- Distinctive Appearance: Half moon diamonds offer a unique, eye-catching look that stands out from traditional cuts
- Perfect Complementary Stones: They beautifully enhance and frame center stones, particularly emerald, oval, and cushion cuts
- Cost-Effective Option: As side stones, they typically cost less than equivalent carat weights of round brilliants
- Design Versatility: Their shape allows for creative and unconventional jewelry designs

How Much Do Half Moon Diamonds Cost?
Half moon diamonds are typically sold in matching pairs, as they're often used as complementary side stones. At Labrilliante, our lab-grown half moon diamonds offer exceptional value compared to their mined counterparts while maintaining identical physical, chemical, and optical properties.
The pricing of half moon diamonds depends on several key factors:
Size (Carat Weight): Like all diamonds, larger half moons command higher prices. However, since they're frequently used as accent stones, many customers opt for smaller carat weights between 0.20-0.50 carats per stone.
Cut Quality: The precision of the cut significantly impacts both appearance and price. Well-cut half moon diamonds with minimal bow-tie effect and excellent symmetry are more valuable.
Clarity and Color: As with all diamonds, higher clarity grades (VS and above) and better color grades (F and above) will increase the price.
Certification: Lab-grown half moon diamonds from Labrilliante come with reputable certification documenting their quality characteristics.
Price Range for Lab-Grown Half Moon Diamonds
| Size (Total Carat Weight) | Color G-H, Clarity VS1-VS2 | Color D-F, Clarity VVS1-VVS2 |
|---|---|---|
| 0.50-0.75 ct | $700-$1,200 | $900-$1,500 |
| 0.76-1.00 ct | $1,300-$2,000 | $1,600-$2,400 |
| 1.01-1.50 ct | $2,100-$3,000 | $2,500-$3,800 |
| 1.51-2.00 ct | $3,100-$4,400 | $3,900-$5,500 |
*Note: Prices are approximate and subject to change based on market conditions and specific diamond characteristics.
Half moon diamonds have gained popularity in recent years for both their distinctive appearance and relative affordability compared to traditional cuts. When properly matched and set, these unique stones create a sophisticated look that draws admiration and attention.
Ideal Settings and Design Ideas
Half moon diamonds offer remarkable versatility in jewelry design, with several setting styles that particularly showcase their unique shape. At Labrilliante, we specialize in creating settings that highlight the distinctive beauty of our lab-grown half moon diamonds.
Most Popular Settings
Three-Stone Rings: The most classic application for half moon diamonds is flanking a larger center stone in a three-stone arrangement. This timeless design creates beautiful symmetry and draws attention to the center stone.
Halo Settings: Half moon diamonds can create stunning curved halos around oval, pear, or marquise-shaped center stones, following the contours of the main diamond.
Bezel Settings: For enhanced protection and a sleek, modern look, bezel settings secure the straight edge of the half moon while allowing the curved edge to remain visible.
Channel Settings: Multiple half moon diamonds can be set with their straight edges aligned in channels, creating elegant bands or stackable rings.
Pairing with Different Center Stones
Half moon diamonds complement various center stone shapes:
Pairing Half Moon Diamonds with Center Stones
| Center Stone Shape | Positioning of Half Moons | Visual Effect |
|---|---|---|
| Emerald | Straight edges parallel to center stone | Elongates the overall appearance |
| Oval | Curved edges following center stone contour | Creates flowing, organic lines |
| Cushion | Positioned at corners | Softens angular appearance |
| Round | Curved edges facing outward | Adds unique geometry to classic shape |
| Asscher | Straight edges aligned with center facets | Enhances architectural design |
Creative Design Ideas
Half Moon Only Designs: A series of half moon diamonds arranged in a circular pattern creates a unique floral or sunburst effect.
Asymmetrical Arrangements: Modern designs may place different-sized half moons asymmetrically for a contemporary, artistic look.
Earrings and Pendants: Half moon diamonds make distinctive drop earrings or eye-catching pendants.
Custom Designs: At Labrilliante, we can create bespoke pieces incorporating half moon diamonds in unexpected and personalized ways.
Size Chart and Measurement Guide
When selecting half moon diamonds, understanding proper measurements is crucial—sometimes even more important than carat weight alone. At Labrilliante, we emphasize millimeter dimensions because they directly impact how the stones will appear when set in jewelry.
Why Millimeter Measurements Matter
While carat weight is the standard measure of a diamond's size, half moon diamonds with identical carat weights can have different dimensions depending on how they're cut. When using half moons as side stones or in matched pairs, precise measurements ensure:
- Perfect symmetry in your jewelry design
- Proper fit in pre-made settings
- Harmonious proportions with center stones
Typical Dimensions for Half Moon Diamonds
| Carat Weight (Per Stone) | Length (mm) | Width (mm) | Depth (mm) |
|---|---|---|---|
| 0.15 ct | 4.0 × 2.0 | 1.5 | 1.3 |
| 0.25 ct | 5.0 × 2.5 | 1.7 | 1.5 |
| 0.33 ct | 5.5 × 2.8 | 1.9 | 1.7 |
| 0.50 ct | 6.5 × 3.3 | 2.2 | 1.9 |
| 0.75 ct | 7.5 × 3.8 | 2.5 | 2.2 |
| 1.00 ct | 8.0 × 4.0 | 2.8 | 2.5 |
*Note: These are approximate dimensions. Actual measurements may vary slightly based on the specific proportions of each diamond.
Certification Recommendations
At Labrilliante, all our lab-grown half moon diamonds come with comprehensive certification from respected grading laboratories. We recommend looking for certifications that include:
- Precise millimeter measurements
- Exact carat weight
- Cut, color, and clarity grades

Sparkle and Brilliance: What to Expect
When considering a half moon diamond, it's important to have realistic expectations about its light performance. At Labrilliante, we optimize each lab-grown half moon diamond to maximize its natural brilliance and sparkle.
Comparison to Other Cuts
Half moon diamonds typically display a different light performance than round brilliant diamonds, which are specifically designed to maximize sparkle. The half moon's distinctive shape creates its own unique pattern of light return:
- Brilliant-cut half moons offer more sparkle and fire than step-cut versions
- Step-cut half moons provide elegant flashes of light rather than the scintillation of brilliant cuts
- Compared to round brilliants of equivalent quality, half moons may return approximately 70-80% of the sparkle
Factors Affecting Brilliance
Several elements influence the brilliance of a half moon diamond:
Cut Quality: Properly proportioned half moon diamonds with optimal facet arrangements will reflect more light back to the eye.
Size: Larger half moon diamonds tend to display more noticeable sparkle due to their increased surface area.
Facet Pattern: The number and arrangement of facets significantly impact the stone's light behavior.
Setting Style: How a half moon diamond is mounted affects how light enters and exits the stone.
Enhancing Sparkle
At Labrilliante, we recommend these considerations to maximize the sparkle of your half moon diamond:
- Choose higher color grades (F or better) for maximum light return
- Select VS clarity or higher to ensure nothing interferes with light transmission
- Consider brilliant-cut faceting if sparkle is your priority
- Opt for settings that allow maximum light exposure to the diamond
Buying Guide: What to Look For
Selecting the perfect half moon diamond requires attention to several specific qualities. At Labrilliante, we guide our customers through these essential considerations to ensure they find the ideal lab-grown half moon diamonds for their jewelry.
Key Quality Factors
Symmetry: Perhaps the most critical factor for half moon diamonds, especially when purchased as pairs. Look for:
- Perfectly matched curved edges
- Straight edges that form clean, straight lines
- Balanced proportions between length and width
Clarity: Due to their unique shape, inclusions can be more visible in half moon diamonds:
- VS1-VS2 clarity or higher is recommended
- Avoid inclusions near the straight edge, as they're particularly noticeable
- Lab-grown diamonds from Labrilliante often have superior clarity compared to mined alternatives
Color: For white half moon diamonds, we recommend:
- D-F color or better for a colorless appearance
- Consistent color between pairs (particularly important)
- Consider how the setting metal will influence apparent color
Cut Quality: Evaluate how well the diamond is cut:
- Minimal to no bow-tie effect
- Even facet arrangement
- Proper proportions that maximize the diamond's natural brilliance

FAQ Half Moon Lab Grown Diamonds
Half moon diamonds make excellent choices for distinctive engagement rings. While traditionally used as side stones, they can serve as stunning center stones for those seeking something beyond conventional diamond shapes. Their unique silhouette offers sophistication and individuality while maintaining the timeless elegance expected in an engagement ring. At Labrilliante, we find half moon diamonds particularly appealing in three-stone settings or modern, asymmetrical designs.
Lab-grown half moon diamonds from Labrilliante typically cost 70-80% less than their natural counterparts of equivalent quality. For example, a matched pair of 0.50 total carat weight half moon diamonds with VS clarity and G color might cost $500-$900 for lab-grown versus $1,800-$2,400 for natural diamonds. This significant price difference makes lab-grown half moons an exceptional value while delivering identical physical and optical properties.
While the pointed ends of half moon diamonds can be vulnerable to chipping, proper setting techniques significantly mitigate this risk. Protective settings like bezels, V-prongs, or semi-bezels that secure the straight edge and points provide excellent durability for everyday wear. Labrilliante's lab-grown half moon diamonds maintain the same hardness (10 on the Mohs scale) as natural diamonds, offering exceptional resistance to scratching and general wear.
Several notable figures have chosen half moon diamonds for their engagement rings, helping popularize this distinctive cut. Their elegant appearance and ability to complement larger center stones make them favorites for custom, high-end jewelry designs that make a sophisticated statement while maintaining timeless appeal.
Half moon diamonds work beautifully in various jewelry pieces beyond rings. At Labrilliante, we create stunning earrings where half moon diamonds can be arranged with curved edges facing outward for a modern look, positioned as drops for elegant dangling earrings, or used in creative cluster designs. They also work exceptionally well in pendants, bracelets, and even as accents in brooches, offering versatility across jewelry categories.
The bow-tie effect—a dark area crossing the center of the stone—can occur in half moon diamonds when light doesn't properly reflect through the diamond. While slight bow-ties are common, excessive darkening diminishes brilliance and beauty. Labrilliante minimizes this effect through precise cutting techniques that optimize facet angles. When selecting half moon diamonds, view them from multiple angles to assess any bow-tie effect before purchasing.
Though often used interchangeably, half moon and crescent diamonds have subtle differences. True half moon diamonds have one perfectly straight edge and one curved edge, creating a semi-circular shape. Crescent diamonds typically have two curved edges—one outer convex curve and one inner concave curve—creating a more moon-like appearance. Labrilliante specializes in precision-cut half moon diamonds with geometrically precise straight edges for optimal symmetry and pairing.
No, lab-grown half moon diamonds from Labrilliante maintain their color permanently. Unlike some other gemstones, properly grown lab diamonds have the same stable atomic structure as natural diamonds, ensuring they won't fade, cloud, or discolor with age or exposure to normal conditions. This color stability is one of many reasons lab-grown diamonds represent an excellent investment for long-term jewelry pieces.
