The Best Lab-Grown Diamonds

Diamonds are a great choice for engagement rings because they show that you will love someone forever. When it comes to selecting that special ring to seal their marriage, younger couples are increasingly opting for lab-grown diamonds over mined gems. Cultured diamonds have the same sparkle as mined ones, but are created under precise laboratory conditions rather than being randomly formed underground. Moderators love their flawless design and ethical and eco-friendly production. Even though diamonds are still a couple's favorite symbol of forever, their origins are changing.


Lab-created diamonds now outshine their mined counterparts, thanks to scientific innovation. Inside sophisticated laboratories, precise control of the production process yields stunning diamonds once considered unattainable.

This mastery over manufacturing parameters enables custom-designing diamonds to exhibit maximum brilliance through precision cutting.

Every buyer wants to find the best lab diamond in terms of quality to price ratio. Despite the different requirements for the perfect diamond, let's look at the parameters by which you can choose the best gemstone.

The Best Lab Diamond Color

Color is one of the four Cs that determines a diamond’s quality, and with lab-grown diamonds, you can find exceptional color grades that are rare in mined diamonds. The best and rarest colors fall into the colorless or near-colorless categories. These diamonds face up white and show no hints of a yellow, brown, or gray hue. The very best lab diamond colors include:

  • D, E, F Colorless. 100% colorless and extremely rare, even among lab diamonds. The most coveted colors
  • G, H Near Colorless. Face up colorless unless compared side-by-side with better colors. Excellent quality.
  • I, J Near Colorless. Face up colorless in most settings. Great value for a clean diamond.

Here are a few of the best-colored diamonds that can satisfy you.

Blue Lab-Grown Diamonds

Blue diamonds shine with endless azure allure - the calm, vivid blue of a cloudless sky or the deep blue of the sea's treasures. Mined blue diamonds are exceptionally rare, formed when boron atoms tint the crystalline lattice in exotic hues. Lab-grown diamonds mimic this enticing process, being vibrant blue homogeneous throughout each layer with no need for enhancement. Precision control of the growth environment gifts the gems color to rival even the rarest mined occurrences.

At Labrilliante you can order these exceptional diamonds. We specialize in producing diamonds in incredible blue hues.

Red Lab-Grown Diamonds

Red lab diamonds captivate with their alluring scarlet hue, beckoning the eye into fiery depths that glow as if lit from within. Their crystalline lattices house secrets in scarlet, defects deliberate and precise, bestowing enigmatic shades on these cultured gems.

True red diamonds are very rare. Their price proves equally exceptional, with mined specimens auctioning for up to millions per carat. Lab-grown counterparts deliver the same visual intrigue for a fraction of the cost.

Vivid Yellow Lad-Grown Diamonds

The vivid yellow of lab-grown diamonds holds the warmth of a golden sunrise - rich, radiant color saturating each atomically aligned layer. Mined yellow diamonds rely on the presence of nitrogen atoms to tint the lattice in pale to deep shades. Lab-grown diamonds instead achieve their golden glow through carbon in its purest crystallized form. Unadulterated by excess elements, vivid chroma saturates the gems with resplendent light from within.

The Best Lab Diamond Clarity

As the IF designation denotes, no inclusions or blemishes visible under 10x magnification reside. Moreover, the flawless FL grade signifies optical flawlessness when scrutinized by expert gemologists under any magnification or lighting environment. This complete absence of particulate clouds, feathers, pinpoints and crystals signifies the pinnacle of uniform faceting free from disruptive defects.

Owing to nature’s haphazard variables, barely one in every ten thousand rough diamonds achieves IF status, while FL persists as a near-impossible ideal outside human engineering. Thus, FL and IF gems command exceptional market value, sought-after for peerless light performance resulting from their pristine interior clarity.

By maximizing optical transmission and minimizing any obstructive imperfections, FL and IF diamonds unleash unmatched refractive spectacle through precisely calculated cuts.

Among the best are VVS and VS lab diamonds. VS (very slightly included) or VVS (very, very slightly included) diamonds contain only minuscule inclusions that are hard to see under 10X magnification. These make excellent, affordable choices, though IF still tops the list for perfection.

The Best Diamond Carat Weight

One advantage of lab-grown diamonds is the ability to produce them in carat weights unavailable with mined diamonds. You don’t need to go for max size to get the best diamond. Let’s look at the best carat options:

  • Up to 0.50 Carat. Excellent sizes for accent diamonds, promise rings, and delicate jewelry. Offers good diamond spread at lower costs.
  • 0.50-1 Carat The classic engagement ring diamond size. Allows excellent cut grades while balancing size with price.
  • 1-2 Carat. It makes a significant visual impact with its larger surface area. A great «wow» diamond.
  • Over 2 Carat. Head-turning diamonds with exceptional sparkle. Perfect for anniversary upgrades or special occasion gifts.

If going the lab diamond route, don’t shy away from requesting stones just under magic retail weights (0.99 ct, 1.98 ct). You can save significantly compared to the full carat while getting essentially the same face-up appearance.

The Best Lab Diamond Cut

With lab-grown diamonds, you have access to an array of shapes, from classic round and princess cuts to on-trend ovals and pears. Let’s highlight cuts perfect for the best sparkle:

  • Round Lab-Grown Diamonds. As the most popular diamond cut, the round brilliant can't be beaten in its optical performance. With 58 mirrored facets, it shows unmatched fire and brilliance. Over 75% of lab diamonds sold are round cuts.
  • Oval Lab-Grown Diamonds. One of today’s top trends, oval lab diamonds have a brilliant cut with elongated proportions. Their elongated shape can make hands appear slimmer.
  • Princess Lab-Grown Diamonds. For those desiring a square silhouette, the princess cut offers sharp lines and corners that refract light powerfully. With excellent brilliance nearly on par with rounds, princess lab diamonds make striking centerpieces.

The bottom line is that while all these cuts can achieve excellent polish and symmetry grades, custom cutting is easier with lab diamonds. This allows for ideal angles and alignments for maximum light return and face-up beauty.

If you like unusual designs, choose rare diamond cuts.
