Welcome to Hydray, buy HPHT/CVD laboratory grown diamonds
HPHT synthetic diamonds have been grown in metal flux compounds. In many cases flux relics remains trapped inside the crystal, actually less than 10% of these diamonds are VVS clarity grade. Since these flux compounds are ferromagnetic elements (Ni, Co), even a small inclusion can result the diamond to be attracted by a magnet.
2 · Clarity Diamond uses the CVD (chemical vapor deposition) method of growing diamonds. We start with a seed - essentially, a thin wafer of diamond material. The diamond seed is sealed in a vacuum chamber and heated to 900° fahrenheit, and inundated with carbon rich gasses.
