About Heart Cut Lab Grown Diamonds
Heart Cut Lab Grown Diamonds – Symmetrical Precision, Distinct Geometry
Heart cut lab grown diamonds are defined by their recognisable outline and precise symmetry. This cut requires exceptional proportion control to ensure balanced curves, a well-defined cleft, and consistent brilliance across the stone.
At Variation, each heart cut lab grown diamond is selected based on strict criteria for symmetry, proportion, and optical balance. Featuring IGI-certified grading, our diamonds meet internationally recognised standards and are trusted by customers across Germany and Europe.
What Are Heart Cut Lab Grown Diamonds?
Heart cut lab grown diamonds are genuine diamonds created using advanced CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) technology. They are chemically, physically, and optically identical to mined diamonds.
The heart cut is a modified brilliant cut that combines curved lobes with a pointed base, requiring precise facet alignment to maintain clarity, symmetry, and controlled light return.

Frequently Asked Questions
What makes heart cut lab grown diamonds special? +
Heart cut diamonds are the ultimate symbol of love, featuring a romantic heart shape
created from a modified brilliant cut. They offer strong sparkle with a distinctive,
meaningful silhouette that stands out in engagement rings and pendants.
What size is recommended for heart cut diamonds to show the shape clearly? +
Heart cut diamonds generally show their shape best from around **0.75 carat and above**.
Smaller stones can still be beautiful, but larger sizes make the lobes and point more
defined and easier to recognize from a distance.
What is the best length-to-width ratio for heart cut lab grown diamonds? +
Most people prefer heart diamonds with a ratio close to **1.00** for a balanced,
symmetrical shape. Slight variations are normal, but well-cut hearts should not look
too long, narrow, or overly wide.
Do heart cut diamonds sparkle as much as round diamonds? +
Heart cuts are based on brilliant faceting, so they offer strong sparkle and fire.
While rounds still have the highest light return overall, a well-cut heart diamond
can be very bright and eye-catching.
Are inclusions more visible in heart cut lab grown diamonds? +
Inclusions can be more noticeable in the center and near the cleft (the top indentation)
of a heart diamond. Many buyers prefer **VVS–VS clarity** for a clean, crisp appearance,
especially in larger heart stones.
Are the pointed tip and lobes of heart diamonds prone to damage? +
The pointed tip is the most delicate part of a heart diamond. A secure setting with a
protective V-prong at the tip and well-designed side prongs around the lobes helps prevent
chipping and keeps the stone safe for everyday wear.
Which settings look best with heart cut lab grown diamonds? +
Heart diamonds look stunning in solitaire, halo, bezel, and pendant settings. They are
especially popular as center stones in engagement rings and as romantic focal points
in necklaces and earrings.
Do heart cut diamonds show color more than other shapes? +
Heart diamonds can show color slightly more around the pointed tip and edges. Many buyers
choose **D–H color** to keep the diamond looking bright and white, especially in white metal
settings like platinum or white gold.
Are heart cut lab grown diamonds certified by IGI or GIA? +
Yes. Heart cut lab grown diamonds can be certified by IGI, GIA, and other respected
gemological laboratories, with full grading for the 4Cs and growth method to ensure
complete transparency.
Do heart cut lab grown diamonds come in different sizes and styles? +
Yes. Heart diamonds are available in a wide range of carat weights and proportions,
from delicate accents to bold statement pieces, making them ideal for engagement rings,
pendants, and special occasion jewellery.
