How Much Does a Diamond Ring Cost in 2026?

This guide breaks down realistic price ranges for each scenario, so you can budget with confidence and avoid overpaying.
At Kohinoor Gems, beautiful lab-grown diamond rings start around $449 USD, giving you outstanding value with VVS1 clarity and FG colour.

- Carat weight — the single biggest factor.
- Cut quality — affects brilliance and desirability.
- Colour and clarity — rarer grades cost more.
