About this stone
Zircon is a natural mineral with dispersion approaching diamond's, and it is badly served by sharing three syllables with a synthetic diamond simulant it has nothing to do with. A stone this size shows the fire clearly.
Ratanakiri material, heated to produce the blue. That treatment is universal for blue zircon, stable, and disclosed here as a matter of course.

Certification available on request$650
We’ll send this stone to GIA, SSEF, Gübelin, GRS or Lotus and it ships with the report. Add it at checkout — the stone and the report are paid for together, the stone then goes to the laboratory, and nothing is dispatched until the report is back. Allow three to six weeks.
We use the international laboratories rather than local ones, which is the point of paying for it.
Every listing on this site states its treatment, including when the honest answer is that we don’t know. How we describe stones.
