Two-stone Ring Design

From $1,290.00$1,600.00

Setting price in 14K gold with a plain band. Your centre diamond, any halo or side stones, and other metals are priced in the builder.

  • IGI-certified lab-grown diamonds
  • Fully insured shipping
  • 1 free resize

75% deposit starts your design; the balance is due after you approve the CAD. Paid in full in two steps. We do not offer installment plans.

The Two-stone design family is a starting point for a custom STELLIVON lab-grown diamond engagement ring. A two-stone ring is two diamonds set side by side or in a toi-et-moi arrangement, often in two different shapes.

This listing is a design direction, not a ready-made ring. Your exact diamond, IGI grading report, metal, ring size and complete price are confirmed in a written proposal before anything is made.

What you choose

  • Centre diamond: shape, carat, color and clarity from our IGI-certified lab-grown diamonds
  • Metal: 14K or 18K white, yellow or rose gold, or platinum 950
  • Ring size: confirmed in US and Hong Kong sizes
  • Details: claw style, band width and profile, refined in the sketch and CAD

How a ring is made

  1. Line sketch (approval 1). You choose a setting, metal and ring size, and approve a line-drawing sketch of the design.
  2. 75% deposit. The deposit reserves your chosen stone and starts the CAD work.
  3. CAD (approval 2). Our workshop prepares a CAD drawing with top, front and side views. The balance is due after you approve the CAD.
  4. Making and checks. Production takes about 20 calendar days after CAD approval. The centre stone is matched to its grading report before insured shipping.

Terms in brief

  • Your deposit is refundable if you decide not to proceed before production starts.
  • No returns: custom and one-of-a-kind pieces are final sale once production is authorized.
  • One size change is free (you cover shipping). A change of up to 2 Hong Kong sizes is possible but requires a new band, charged separately; your centre diamond is reused.

Questions about this ring

How is a custom STELLIVON ring made?

We hand-draw a line sketch of your ring first. When you approve it, you pay a 75% deposit and we prepare the factory CAD. You approve the CAD, pay the balance, and making takes about 20 days.

Is the deposit refundable?

Yes, the 75% deposit is refundable until production starts. Once you approve the CAD and production begins, it is no longer refundable.

Can I return a custom ring?

No. Every ring is made to your approved sketch and CAD, so we do not accept returns. You review the design twice before anything is made.

What if my ring size is wrong?

One size change is free (you cover shipping). A change of up to 2 Hong Kong sizes is possible but requires a new band, charged separately; your centre diamond is reused.

Which metals can I choose?

14K or 18K white, yellow or rose gold, or platinum 950. Your metal is confirmed on the line sketch and again on the CAD.
