what is uncut White HPHT rough Lab-Grown diamond
Uncut white HPHT rough lab-grown diamond refererer til en type diamant, der dyrkes i et laboratorium ved hjælp af højtryks høj temperatur (HPHT) technology and has not been cut or polished yet. HPHT lab-grown diamonds are created by replicating the high-pressure and high-temperature conditions that occur naturally deep in the Earth’s mantle, hvor diamanter dannes. A small diamond seed is placed in a chamber that is filled with carbon and subjected to extreme heat and pressure. Kulstoffet i kammeret smeltes og opløses, og derefter langsomt afkølet, får kulstoffet til at krystallisere omkring diamantfrøet, danner en større diamant.
Uncut white HPHT rough lab-grown diamonds are chemically and physically identical to natural diamonds, and they have the same hardness, density, and brilliance as natural diamonds. They are also graded using the same criteria as natural diamonds, including the 4Cs (carat weight, skære, klarhed, og farve).
The advantage of uncut HPHT lab-grown diamonds is that they are typically less expensive than natural diamonds, fordi de kan produceres mere effektivt og uden omkostninger forbundet med minedrift og miljøbelastning. Derudover, uncut lab-grown diamonds offer more flexibility in terms of customization, as they can be cut and polished into any shape or size desired.
