The weight of a diamond can also be expressed in "minutes". The weight of 1 carat is equal to 100 cent, so a diamond weighing 75 cents is equal to 3/4 carat (unlike what some people think: there are 75 points on such a diamond).
1, diamond grade vs, vvs, s, etc. Vvs has the best definition and is also the most expensive.
2. The heavier the diamond, the more expensive it is, but 0. The weight of 0xxx generally has no diamond grade, which means that it is too small to detect the diamond grade at all. If you don't believe me, diamonds within 2000 are generally 0. 0 carats, and there is no diamond grade on the certificate.
3, ring holder, divided into pd950, pt950 and a 750, pt950 is platinum (first of all, "platinum" and "platinum" can not be distinguished, that is, platinum is regarded as platinum. In fact, platinum and platinum are essentially different. PLATINUM, called platinum in English, is abbreviated as Pt, and only platinum can be marked with PT. Platinum can be said to be the rarest precious metal in the world, mainly produced in South Africa and Russia.
And "white gold", or "k platinum", is actually k gold which is fused by gold and other white alloys, and its gold content is generally 75%, which is white due to the addition of other white metal elements. WHITEGOLD's English name is Whitegold, abbreviated as WG. Platinum cannot be marked with Pt, and platinum is not platinum. Platinum and platinum are only because of the pronunciation of Chinese. Some people read platinum as platinum, especially the older generation often confuse platinum with platinum, but it is easy to distinguish it by English pronunciation. Personally, I think pd950 is enough. The difference between pt950 and pd950 per gram is about 200 yuan, and pt is the most expensive.
