8.0 × 6.0 × 3.5 mm · 4.2 ct · Mohs 7–7.5 · untreated
For makers
Calibrated, measured, bezel-ready.
You need to know a stone will fit before you buy it. So we measure to the millimetre, state the inclusions, and tell you what the stone will and won't survive at the bench.
What makers actually ask us
- Will it fit a standard bezel cup, or is it freeform?
- Is the dome high enough to set without the girdle chipping?
- Are there fractures that will open under pressure?
- Is it heat-sensitive, or soft enough to scratch in wear?
Every listing answers what we can measure, and says plainly what we can’t. If a stone has a setting consideration, it’s on the listing before you buy — not discovered at the bench.
