Heart Cut Lab Grown Diamonds
Heart cut lab-grown diamonds are shaped like a heart, featuring a pointed top and a rounded bottom. They feature a large open table and a symmetrical shape, with typically 56 to 58 facets that are cut and polished to reflect light and create a dazzling sparkle. The shape and angle of each facet is precisely calculated to enhance the diamond's brilliance, fire, and the way light interacts with the diamond.
The length-to-width ratio is also an important aspect for determining the diamond's overall appearance, an ideal ratio of 0.90 to 1.10 is considered perfect for a symmetrical shape. At LaBrilliante, we craft heart cut lab-created diamonds of superior quality that radiate their maximum potential light.

How to Choose the Perfect Heart Cut Lab-Grown Diamond?
The Heart Сut Lab-grown Diamond is a cut, which means it's adept at concealing minor imperfections, much like round diamonds. Opting for a clarity grade in the range of VS2-SI1 is an excellent choice to acquire a beautiful gemstone without breaking the bank. However, it's essential to emphasize the need to inspect the diamond before purchasing. While small inclusions near the edges may not be visible, a heart-shaped diamond should be considered "eye clean" to truly showcase its beauty.
Selecting the color for heart cut lab diamonds is relatively straightforward. Similar to round brilliant diamonds, heart cuts can mask some degree of yellowish tones by displaying an impressive play of light and sparkle. Diamonds with J and I color grades can still appear white to the naked eye, offering an opportunity for cost savings. Nevertheless, venturing below the near-colorless range is not advisable, as it could result in acquiring a diamond with a grayish hue.
The History of Heart Cut Diamonds
The heart-cut diamond is a unique and romantic diamond cut, known for its distinctive shape and sparkling brilliance. The invention of the heart-cut diamond is credited to a Belgian diamond cutter named Lodewyk van Berken in the early 20th century.
According to the story, van Berken was commissioned to cut a diamond for a wealthy client who had requested a diamond cut in the shape of a heart. At the time, diamond cutting was a highly skilled and labor-intensive process, and there were no existing techniques for cutting a diamond into the shape of a heart.
Van Berken took on the challenge and spent months experimenting with different cutting techniques and angles. He eventually developed a new cutting method that involved creating a series of small, triangular facets around the perimeter of the diamond, which were then carefully shaped and polished to create the distinctive shape of a heart.
The heart-cut diamond was born, and soon became popular among jewelers and customers alike for its unique and romantic appearance. The heart cut diamond is a brilliant cut and is known for its unique and romantic appearance. The cut is not so common, but is considered a symbol of love and devotion.
The technical details of the heart cut diamond are that it is a modified round brilliant cut, with the bottom half of the diamond cut in the shape of a heart and the top half cut as a round brilliant. The main challenge of this cut is to achieve a symmetrical heart shape while maintaining the diamond's fire and brilliance. To achieve this, the diamond cutter must carefully plan the placement and angles of the facets to create a pleasing balance of light and dark areas, known as the diamond's "pattern." The cutter must also pay close attention to the diamond's "girdle" (the narrow band around the diamond's middle) to ensure it is even and does not interfere with the overall shape of the heart.
