A 1-carat diamond ring is worth 100 points. According to the conversion of diamond units from carats to points, 1 carat=100 points=0.2 grams. Similarly, a 0.5 carat diamond ring is worth 50 points, and a 0.2 carat ring is worth 20 points.
The impact of carat number on diamond value
1. The higher the carat number, the higher the price
Although there are many factors that affect the price of diamonds, the weight of diamonds directly affects their price. This is mainly because diamonds are a natural and rare item, and intact large diamonds are even rarer. Therefore, diamonds with large carats are more expensive, especially those over 1 carat.
2. Diamonds over 1 carat have resale value
Diamonds priced in fractions of 30 or 50 can only be used as decorative items. Their resale and appreciation values are very low, and few people recycle diamonds under 1 carat. If you consider the value of diamonds, it is best to buy high-quality ones above 1 carat.
