Lab Grown Diamonds

Natural VS Lab-Grown Diamonds

 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.

  The above two types have investable value and will maintain or increase their value. Generally appearing in high-end auction houses, ordinary people should not consider it. These are two markets, the consumer market and the collection market.

  If the price of lab grown diamonds is about three to a quarter of that of natural diamonds under the premise of the same level, there will be a certain advantage in price. If you only pursue cosmetic effects, cultivated diamonds are undoubtedly a good choice.

  Natural diamonds grow in multiple directions under high temperature and high pressure for a long time. Cultivation of diamonds hthp simulates the high temperature and high pressure multidirectional growth in the underground environment. Cvd is the high temperature and high pressure unidirectional growth in the reactor.

  Human made diamonds and natural diamonds differ only in the environment in which they are created, and have exactly the same characteristics in terms of raw materials, chemical composition, optical properties, physical properties, and crystal structure. Even a diamond tester will tell you that a diamond is a real diamond, and even professional appraisers have difficulty distinguishing it from a natural diamond. Lab-grown diamonds are scientifically proven to be "real" diamonds, not merely "similar" looking stones such as cubic zirconia.

  All diamonds over 0.5 ct come with a certificate of authenticity.The quality of each lab-grown diamond is certified by a certificate of authenticity issued by the International Gemmological Institute (IGI), which is recognized by diamond exchanges around the world for its strict quality standards.

Q: Do natural and Lab diamond have the same effect?

A: In fact, the general effect to the naked eyes is the same, the dispersion value of the index of refraction and the natural diamonds are the same.

Q: Are the standards the same for both?

A: The standards for both natural and Lab diamond are the same, using the 4C standard.

Q: Is there a certificate for Lab diamond?

A: Lab diamond have certificates, common certificates are GIA (Gemological Institute of America), IGI (International Gemological Institute), NGTC (National Jewelry and Jade Quality Supervision and Inspection).

Q: What's the difference between HPHT and CVD?

A: First of all, both are Lab diamond and both are real diamonds, generally more HPHT below one carat and more CVD above one carat. There is not much advantage in size, but the colour level is slightly better than CVD. Nowadays CVD also have a lot of change to colourless DE colour, and HPHT can usually reach DE colour. Overall, there is no better or worse way to wear both on a daily basis.

Q: Do Lab diamond come in shapes?

A: Yes, the round ones are relatively affordable while the shaped ones are more expensive.

Q: Why are Lab grown diamond so expensive?

A: It's actually a matter of the raw materials and the production process. Lab diamond cost from raw materials, production time, machines, cutting and grinding.

Q: Does Lab diamond have a waist code?

A: Yes, the normal delivery of the cultivation of diamonds are belt code, it and the diamond identification certificate on the number of the same, such as a diamond ID number, each belt corresponds to a diamond certificate number.

Q: Does uncut diamonds have a guaranteed value?

A: Lab diamonds do not retain their value and may not be exchanged for much money when they are liquidated, the difference is huge.
