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.

Treatment & certification
Heated
Conventional heating with no foreign residue. Heat is a permanent, stable and near-universal practice in sapphire — the great majority of stones on the market are heated.
How we know
Heated — the standard and permanent treatment that produces blue in Ratanakiri zircon. Effectively all blue zircon on the market is heated.
Certification arranged by written quote
Before any laboratory service is purchased, we agree the laboratory, its current fee, insured carriage, expected timing and what happens if the result changes the existing description. Nothing is dispatched until the agreed work is complete.

Every listing on this site states its treatment, including when the honest answer is that we don’t know. How we describe stones.
Evidence provenance
This is an educational record. Its values demonstrate the format and do not represent an owned stone or publication-approved evidence file. It cannot be purchased or exported as a product.
Shipping, inspection and care
No carrier promise is inferred from this page. At checkout the live service must find a recently verified route that accepts loose gemstones, the destination and the full declared value.
You have seven days from delivery to request a change-of-mind return, in addition to rights under Australian Consumer Law. Read the inspection and return process.
Keep the stone loose, dry and separated from harder material. Do not use heat, chemicals, ultrasonic cleaning or steam without advice specific to the species, treatment and condition. Rough and specimens should not be altered during the inspection period.
