The price of a diamond wedding ring comes down to three things: the gold, the diamonds, and the workmanship. Two rings that look alike can differ by millions of rupiah because their gold weight and total diamond carat are not the same. This guide explains the seven factors behind the price, so you can compare offers from different jewelers fairly.
Quick summary
- Gold: purity (karat) and weight in grams.
- Diamonds: number of stones, total carat weight, quality, and certification.
- Workmanship: how complex the design and diamond setting are.
- Market: world gold prices and the US dollar exchange rate, which keep moving.
1. Gold purity
18K gold is 75% pure gold. The rest is alloy, which makes the ring harder and suitable for daily wear. The higher the purity, the higher the price per gram. Kimfook works only in 18K gold, and the purity can be tested in the showroom with an XRF tester.
2. Gold weight
Gold weight is measured in grams and is the easiest part of the price to compare. A wider or thicker band needs more gold. A man’s ring is usually heavier than a woman’s, and a larger finger size adds weight too.
3. Number of diamonds and total carat weight
Total carat weight is the combined weight of every diamond in the ring. A band with one small diamond is priced very differently from a band with a full row of diamonds. When comparing, look at the total carat weight, not only the number of stones.
4. Diamond quality
Diamonds are graded on the 4Cs: carat, color, clarity, and cut. Two diamonds of the same weight can differ a lot in price when their color and clarity differ. Ask about the quality of the diamonds, not only their weight.
5. A GIA-certified center diamond
A diamond with a GIA report has been examined by an independent laboratory, so its quality is on record. At Kimfook, single diamonds of 0.2 carat and above are generally GIA certified, while small accent diamonds are not certified one by one. See also our comparison of 0.3 and 0.5 carat GIA diamonds.
6. Design and workmanship
A plain band is quicker to make than a design with many details or a complex diamond setting. The craftsman’s time is part of the price. At Kimfook, production normally takes 5 to 14 working days, and up to 3 weeks in high season.
7. Gold prices and the dollar exchange rate
Gold and diamond prices follow world markets and the US dollar exchange rate. That is why the same ring can cost a different amount from one month to the next. If you find an old price online, always check the current one before deciding.
How to compare prices fairly
- Ask for the gold purity and the gold weight in grams.
- Ask for the total carat weight and the diamond quality.
- Confirm whether the diamonds are natural or lab-grown. Lab-grown diamonds cost far less than natural diamonds, so the two cannot be compared directly.
- Make sure both prices are for a pair, or both for a single ring.
- Ask about certificates and after-sales service.
