About this stone

Alexandrite is priced on the completeness of its colour change before anything else, and under a carat the good ones are already difficult. This stone reads a clear bluish green in daylight and goes to a raspberry purple-red under incandescent, with no muddiness in between — the swing is complete rather than partial, which is the thing that actually sets the price.

From Hematita in Minas Gerais, called by GIA. Slightly included under 10×; the inclusions do not disturb the face-up appearance in either light.

Photographed in both lights — see the gallery. Any alexandrite photographed in only one light is telling you half a story.

Calibrate the size

ANY BANK CARD
The stone’s 6.1 × 5.2mm outline, drawn to the same scale as a bank card. Hold one against the screen and the stone beside it is life size — if the card does not match, zoom until it does. The outline is the idealised shape rather than this stone’s own profile; the photographs are the stone.

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.
