100% Clean And Pure CVD Man Made Lab Created Uncut Rough Diamonds For Making Cvd Diamond Jewelry
Deskripsi CVD Lab Grown Diamonds
Lab-grown diamonds are real diamonds.
There are two ways to create rough lab-grown diamonds. They are HPHT and CVD methods.
The HPHT diamond cultivation process takes place in a small capsule in a device with ultra-high pressure. In this capsule, the diamond powder is dissolved in the molten metal solvent and then begins to crystallize to form diamond crystals. The entire crystallization process will take weeks or even months. At a time, one or more crystals are produced.
In order to cultivate colorless HPHT diamonds, apart from the need to isolate nitrogen during the cultivation process, the cultivation of high-purity colorless diamonds (type IIa or weak type IIb) often requires a longer cultivation period and stricter temperature and pressure conditions. Sebagai akibat, the cultivation cycle is longer than that of type Ib synthetic diamonds, so how to use HPHT synthesis to grow large-grain crystals has always been a problem. Namun, with the development of technology, it is now possible to use HPHT synthesis to grow more than 10 carats of Diamond crystals too.
Deposisi Uap Kimia (CVD) is a method of decomposing raw materials at high temperatures to produce active particles such as carbon atoms or methyl groups and depositing and growing a diamond film on the substrate (substrate) under certain process conditions Methods.
CVD-grown synthetic diamonds do not contain metal inclusions. But they usually contain dark graphite inclusions or other mineral inclusions, which are formed during their unique growth process. Graphite inclusions are different from metal inclusions in that they have no metallic luster.
Whether laboratory-grown diamonds or natural diamonds, loose diamonds after cutting and polishing can not be distinguished by the naked eye. It can be detected only with the help of professional equipment. With professional equipment, the comparison of the color, crystal shape and crystal surface characteristics, internal inclusion characteristics, absorption spectrum and ultraviolet fluorescence characteristics of the tested diamonds can completely distinguish the artificially cultivated diamonds from the natural diamonds
Pendahuluan CVD Lab Grown Diamonds
Berlian alami diciptakan oleh alam dan merupakan hasil dari suhu dan tekanan tinggi yang terbentuk selama miliaran tahun. Berlian Rough Lab Grown diproduksi di laboratorium, biasanya dalam beberapa minggu. Perbedaan kimia antara keduanya adalah sama.
Jadi bagaimana Anda membedakan antara Rough Lab Grown Diamonds dan berlian alami?
Tidak ada perbedaan yang jelas antara Rough Lab Grown Diamonds dan berlian alami. Bahkan ahli permata profesional membutuhkan peralatan khusus untuk mengidentifikasinya. Dengan memperbesar, profesional akan dapat membedakan kontras halus dalam inklusi berlian tumbuh dan ditambang di laboratorium.
