Carat
Weight, not visual sizeCarat measures weight. Price rises non-linearly at milestone weights such as 1.00, 1.50 and 2.00 carats. Cut proportions also determine how large a diamond faces up.
The diamond & pricing guide
Two lab-grown diamonds of the same weight can look different and carry different prices. The difference lies in the complete combination of quality, proportions, shape and certification—not in one grade alone.
The four universal quality factors are a useful starting point. The value comes from how they work together.
Carat measures weight. Price rises non-linearly at milestone weights such as 1.00, 1.50 and 2.00 carats. Cut proportions also determine how large a diamond faces up.
Cut controls brilliance, fire and visual balance. For round diamonds it receives a laboratory grade; for fancy shapes, proportions and appearance require expert evaluation.
For white diamonds, the GIA scale runs from D to Z. Small grade differences can affect price, while personal preference and metal color can make near-colorless grades an intelligent choice.
Clarity describes inclusions and blemishes. The grade matters, but so do the inclusion’s location, type and visibility. An eye-clean diamond can offer better value than paying for rarity you cannot see.
Lab-grown diamonds have the same crystal structure, hardness and optical properties as mined diamonds. The difference is their origin—and the more accessible price it makes possible.
Round diamonds generally command a premium. Fancy shapes are priced differently according to demand, yield and the beauty of their individual outline.
An independent laboratory report documents the stone’s measured characteristics and origin. At LILYAN, lab-grown center diamonds of 1.00 ct and above include an IGI report.
