24K: 100% pure gold
18K: 75% pure gold
14K: 58.3% pure gold
10K: 41.7% pure gold

3. Calculate the Pure Gold Content Using the Formula
The formula is as follows:
Pure Gold Content (g Total Weight of Jewelry (g × (Grading/24
For example, assuming an 18K gold piece weighs 10 grams:
Pure Gold Content 10g × (18/24 7.5g

Other Metal Content (g Total Weight of Jewelry (g Pure Gold Content (g
Continuing with the previous example:
Other Metal Content 10g 7.5g 2.5g

5. Estimate the Value
Once the pure gold content is known, the value of the jewelry can be computed based on current gold market prices.
Current Gold Price (e.g., 200 yuan per gram:
Value Pure Gold Content (g × Current Gold Price
For instance, 7.5g × 200 yuan/g 1500 yuan
