An engagement ring upgrade with a lab-grown diamond is priced like a new custom piece, and it follows the same stages and the same deposit structure.
We do not publish a price list for upgrades, because the price depends on the choices you make. This guide follows the upgrade path on our engagement page.
Priced like new custom work
An upgrade is custom work, quoted for what you choose, not a discounted add-on to your current ring. Two upgrades can have very different prices: one replaces your current center stone, the other only resets it.
What drives the cost
- A new lab-grown center stone. Its shape, size and grades are the largest factor. Each lab-grown diamond we present comes with its own price.
- A new setting. The design, the metal and the amount of detail.
- Resetting only. Your current stone is not part of the cost; the work is the new setting.
- Both. A new lab-grown center stone and a new setting add together, as in a new ring.
Fees and deposits
The CAD design takes 1 to 2 weeks, with 2 to 3 revision rounds included.
Production starts after a deposit. Fee and deposit terms: see our Terms of Service.
How long each stage takes
Replacing your current center stone adds a sourcing stage. A standard search takes 3 to 10 business days. If you reuse your current stone, there is no search to wait for.
Expedited search is available on request.
After sourcing, the CAD design takes 1 to 2 weeks. The build takes 3 to 6 weeks.
A reset with the stone you already own begins at design; a full replacement begins at sourcing.
Shipping and inspection
Shipping on custom pieces: see our shipping policy. Inspection after delivery: see our return policy.
What to ask us
- Which route fits what you want to change.
