4.11ct Cushion D VS1 Lab-Grown Diamond

The diamond is absolutely colorless — the highest color grade and rarest in lab-grown diamonds. Its clarity of VS1 means it is very slightly included — minor inclusions difficult to see under 10×. Measuring 11.7x8.12x5.18 mm, this stone has been precision cut to maximize the return of light through the table.

High Pressure High Temperature (HPHT) — diamonds are grown by replicating the deep-earth conditions of natural diamond formation. Lab-grown diamonds are real diamonds — chemically, physically and optically identical to mined diamonds, with the same fire, brilliance and 10/10 Mohs hardness. They are an ethical, sustainable and accessible choice, offering exceptional value without compromising on quality.

Clean with a soft brush, warm water and a drop of mild dish soap. Pat dry with a lint-free cloth. Store separately from other jewellery to avoid scratches. Avoid abrasive cleaners. Ultrasonic and steam cleaning are generally safe for colorless lab-grown diamonds but should be avoided for fancy color stones to preserve their hue.
