The diamond size of the ten carat diamond ring is 2g. The weight of the diamond is measured in carats. 1 carat is equal to 0.2 grams. One carat is divided into one hundred points, for example, 0.75 points is also called 75 points. Diamonds of the same weight will have very different prices due to differences in color, clarity, and cut.

A diamond ring with a score of 20 or above will have an appraisal certificate (you can issue a certificate for diamonds of any size if you wish), which contains the diamond's weight, clarity, cut, and color grades. Generally, a US GIA certificate will be issued for those with a score of 30 or more. Each diamond has a unique laser code, which can be checked on the website.

Key points for diamond ring maintenance:

1. Do not hit the diamond ring when maintaining it. Diamond is the hardest thing in the world, but it is actually very afraid of impact. Due to its special molecular structure, although it can carve marks on any gemstone, it cannot withstand collisions. Especially for "prong set" diamonds, the girdle of the diamond is very fragile.

2. The maintenance of diamond rings requires regular annual inspections. Diamonds are often lost due to loose settings. It is recommended that diamond jewelry be inspected every year to check the settings and re-reinforce and polish them.

3. Professional cleaning is required to maintain diamond rings: Diamonds are lipophilic gemstones and are easily contaminated with oil, so you should take off diamond jewelry when applying hand cream. It cannot be worn while swimming, as chloride bleach in the water will corrode diamonds. It is recommended to choose professional jewelry cleaners and instrument cleaning.

4. When maintaining diamond rings, store them in categories: Store different gemstones in categories to prevent hard diamonds from scratching other gemstones. To prevent jewelry from darkening, place a piece of chalk to absorb moisture.
