Certified loose diamonds — GIA natural, IGI lab-grown, every shape and carat. Build your own ring around the exact stone you select.

Build Your Own Ring — The Process
- Select the loose diamond — in-store or sourced to spec in 48 hours.
- Choose setting + metal — solitaire, halo, three-stone, bezel; 14K/18K gold or platinum.
- CAD render for approval — unlimited adjustments before metal is cut.
- Bench work — 3–5 weeks for engagement rings, 2–4 for pendants and stud pairs.
Total turnaround: 3–6 weeks. Typically 30–50% less than equivalent name-brand retail — no brand markup.
