What to look for when buying wholesale

  • Distinguish Paraiba (copper-bearing) from neon-blue but copper-free tourmaline — labs verify with chemistry.
  • Brazilian Paraiba carries the highest origin premium; Mozambican is the modern supply.
  • Chrome tourmaline from Tanzania is rare and strong-green.

Certification guidance

For Paraiba claims, always insist on GIA, SSEF or Gübelin chemistry-verified origin reports.

Treatment disclosure

Most tourmaline is sold untreated; heated and irradiated material exists and must be disclosed.

Typical wholesale price tiers

Cuts and shapes

Tourmaline 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.
