Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They have the same crystal structure, hardness (10 on the Mohs scale), refractive index, and thermal conductivity. The only difference is their origin — grown in a controlled laboratory environment in 6–10 weeks rather than formed over billions of years. Lab-grown diamonds are typically 60–80% less expensive than equivalent natural diamonds, allowing you to choose a larger, higher-quality stone within your budget.
The Asscher cut is a square step-cut diamond with deeply cropped corners that create an almost octagonal outline. Its concentric square facets draw the eye deep into the stone, producing a mesmerising windmill pattern. Invented in 1902 by the Asscher Brothers, it remains one of the most distinctive and collectible diamond shapes.
