There are many, many factors that contribute to the value of a diamond and a ring.
The information in this blog post is intended to give you a guide only.
If you are genuinely interesting in selling, to get an accurate guide, we encourage you to contact one of the following to receive an offer:
- Brand name e.g. Tiffany, Bvlgari: The Diamond Oak
- A ring with over 1.2 carats of diamond: The Diamond Oak
- A ring with 0.5 – 1.2 carats (and likely to be worth more than $1,000): Worthy
- Any other jewelry, or where the diamond is less than 0.5 carats: Express Gold Cash
When building our calculator, we included the following assumptions:
Assumptions in the diamond value calculator
The diamond prices used in the calculator are based on a markdown of 50% of the 2022 retail market prices for diamonds of a particular shape, carat weight and quality. This current fair market price may be significantly lower than your original purchase price.
Diamond melee prices
Small ‘melee’ diamonds that are used in the setting e.g. around the halo, do not have any value in the calculator. Removing them can be an expense for a jeweler, rather than a value-add.
Precious metal prices
Precious metal prices (ie. the gold or platinum in the setting) are costed at 70% of the Mayy 2022 spot price.
‘Signed’ or luxury brands
Luxury branded rings e.g. Tiffany, Cartier, Bvlgari etc, are priced 30% higher than generic branded diamond rings to reflect the greater secondary market for these items.
