Carat (Ct) is the unit of mass (weight) of gemstones. Now 1 carat is equal to 0.2g or 200mg .. One carat is divided into 100 minute, such as 50 minutes or 0.5 carat, which is used to calculate smaller gemstones. Because the density of gems is basically the same, the heavier the gem, the bigger the volume. The bigger the gem, the rarer it is, and the higher the value per carat.
Pt950 refers to an ornament with the imprint of Pt950, which contains 95% platinum and 5% other precious metals. Platinum is very flexible.

This quality combined with the strength of platinum enables jewelers to create extremely flexible mesh platinum jewelry, which other precious metals can never do.
