As the growth in CVD method can not make the size of diamond larger, size of seed dominate the final diamond gem stone weight. The largest seed from EDP is 10x10mm and this can fabricate 3 crat or larger loose. You can select the size .
4. The use of Synthetic Diamond is highly used in the industrial applications like lasers and electronic sensors. 5. The creation of electronic wafers is done by the use CVD diamond injecting about 200 million carbon atom in the manufacturing process. 6. Synthetic Diamond also helps in formation of electrochemical substances, conventions.
TO GROW. STEP 4: DIAMOND IS READY. Our lab-created diamonds are, as their name suggests - made in a laboratory. Each diamond starts its life as a tiny carbon seed. It is then exposed to extreme heat and pressure or entered into a deposition process (known as CVD), to mimic the process of natural diamond formation.
Lab grown diamonds are generally produced by chemical vapor deposition (CVD) or high pressure high temperature (HPHT) methods. CVD uses ultra-pure carbon-rich gases in a controlled environment. It produces Type IIa diamonds, which are quite rare in nature and account for less than two percent of all mined diamonds.
