The first generation of cinerary diamond technology prevailed during 2005-2009. The technology of bone ash diamond in this period is quite immature, which requires a lot of bone ash (about 500 grams, so it can't be customized for pets), and it can only be made into a single color (only blue, not the purest white). It takes six months to a year to cultivate diamonds, and now most companies have eliminated them. The purity of the first generation technology is not high, and only blue-gray diamonds can be made.
The second generation of bone ash diamond technology
The second generation technology was used during 2009-20 12. The technology in this period has been developed. Only 150g ashes are needed, and the amount of pet ashes can also be made into ashes diamonds. Five colors can be achieved through different temperatures and pressures (HPHT technology). The second generation technology can make the purest white, but because the technology of white is complex and the cultivation environment is demanding, the cost is high.
The third generation of bone ash diamond technology
After 20 12, the third generation technology prevailed. Only 100g of ashes is needed, and 100% of the extracted carbon can be used for diamond cultivation. Colored diamond can cultivate 1 carat, or even 2 carats. And it only takes 3-4 months. Today, the price of ashes diamonds is 6999.
