Hpht diamond bulk provider from China: What are the certifications for lab-grown diamonds? It is possible and advisable to certify lab-grown diamonds. Diamonds without diamond certification should not be purchased. No matter where a diamond comes from, it should undergo a grading process that takes the 4Cs into consideration. Are natural diamonds better than laboratory diamonds? If their 4C grades are the same, then at least, they look the same to the naked eye. It should be said that the high-grade loose diamonds of large carats are generally not seen on jewelry, starting with 3~5 carats of white diamonds. There are large carat colored diamonds with high color grades. See extra information on https://www.messigems.com/lab-grown-diamonds.html.
IGI lab diamond – Finally, let’s talk about the 4Cs that determine the value of a diamond: Carat, in terms of diamond size, it depends on personal preference and budget. However, when the diamond ring is worn on the hand, with the accumulation of years, it may have the feeling of getting smaller and smaller, so it is recommended to put most of the budget on the diamond size. Color , diamond color from light yellow-brown to colorless bright white has been divided into 23 grades, from high to the bottom are D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z. Usually, diamonds I color or more will be more, on the H color belongs to the colorless, it is a cost-effective choice.
GIA (Gemological Institute of America), in terms of natural diamonds to give the identification results are indeed detailed, but in the cultivation of diamonds in this regard is not perfect, and even a bit of “special treatment” – the cultivation of diamonds 4C identification results of fuzzy treatment, although the subsequent improvement, but the price of appraisal is also high. NGTC (National Jewelry and Jade Quality Supervision and Testing Center), the National Inspection is certainly authoritative, but for the cultivation of diamond 4C grading of this piece of words, the National Inspection will be slightly simple and rough, not detailed enough.
But ash diamonds, can be arbitrarily selected red, yellow, blue and green: for example, control the nitrogen content will be able to create orange-red or light yellow diamonds, control the boron element will be able to create blue diamonds, like colored diamonds, it is difficult not to be moved. Moreover, the vast majority of colored urn diamonds are even less expensive than white urn diamonds, because making white requires extracting the purest carbon and a higher technical threshold. Natural diamonds can never be directly linked to any individual, but cultivated diamonds, whose “DNA” is the wealth code, can.
Recently, a small red book on the topic of “died puppy into a diamond” fire, the blogger said, in memory of the deceased love pet, she collected puppy ashes and her own hair, handed over to the company carbonized into a diamond ring. The price of these artificial diamonds is not expensive, one carat of loose diamonds plus the setting process will require more than 40,000 yuan, and can be customized, the style of change has no upper limit, but the price is the average worker can not afford.
Temperature and pressure are also two key factors in the manufacture of crystals, which are made in ceramic vessels rather than underground, where water pressure provides high pressure and electricity generates high temperatures, causing carbon to form crystals around seed crystals of 1 mm in diameter, made from natural diamonds. HPHT diamonds are also known as “Type IIa” diamonds, which are characterized by their lack of nitrogen impurities. This results in a very high level of purity and exceptional clarity compared to other types of synthetic diamonds or natural diamonds.

Choosing stone – The diamonds or gemstones are hand-sorted by the receiving and shipping department according to the jewelry design drawings, selecting the appropriate color, cut and size matches, ready for setting. Setting is an important aspect of jewelry making, as each diamond and gemstone must be set by hand. If the design is simple, the setting is relatively easy, but if the design involves complex techniques or a large number of stones, the difficulty increases exponentially.
