Typical treatments
None standard — synthetics common, declare!

What to look for when buying wholesale

  • Strength of colour change is everything: 100% (full) is the trade benchmark.
  • Synthetic and simulated alexandrite is everywhere — always require lab confirmation.
  • Russian provenance commands a 3–5× premium and SSEF/Gübelin reports are the trade standard.

Certification guidance

Any natural alexandrite over USD 1,500 should travel with a recent independent lab report stating natural origin and colour-change percentage.

Treatment disclosure

Natural alexandrite is almost never treated; synthetics are the main risk and must always be disclosed.

Typical wholesale price tiers

Cuts and shapes

Alexandrite is faceted into the same core shapes seen across coloured stones and diamonds — round, oval, cushion, emerald-cut, pear, radiant, princess, asscher, marquise and heart — plus antique cuts such as old mine and old European, most associated with period diamond jewellery.
