When constructing our calculator, we included the next assumptions:

Assumptions within the diamond worth calculator

Diamond worth

The diamond costs used within the calculator are based mostly on a markdown of fifty% of the 2022 retail market costs for diamonds of a selected form, carat weight and high quality. This present truthful market worth could also be considerably decrease than your authentic buy worth.

Diamond melee costs

Small ‘melee’ diamonds which might be used within the setting e.g. across the halo, do not need any worth within the calculator. Removing them will be an expense for a jeweler, slightly than a value-add.

Precious metallic costs

Precious metallic costs (ie. the gold or platinum within the setting) are costed at 70% of the Mayy 2022 spot worth.

‘Signed’ or luxurious manufacturers

Luxury branded rings e.g. Tiffany, Cartier, Bvlgari and so forth, are priced 30% increased than generic branded diamond rings to mirror the larger secondary market for these things.
