Buy Star Rubies in Beruwala, Sri Lanka

Glowing six-ray stars in purplish-red corundum — genuine star rubies are genuinely rare. Confirm treatment and origin with the dealer on every piece.

Star ruby is the rarest of the star stones — a cabochon-cut ruby with a six-ray star floating across its surface. Genuine star rubies come from a handful of sources including Sri Lanka, Burma and Vietnam, and good examples combine a strong, saturated red body colour with a sharp, well-centred star.

Heating can destroy the fine silk inclusions that create the star, so star rubies are often unheated — but treatment should still be disclosed, and fissure-filled material is not unusual in the wider market. Judge the star in person or on video under a focused light: it should be clearly visible and move cleanly across the dome. Because fine star rubies are genuinely scarce, compare carefully and treat unusually low prices with caution.

What to check when buying star rubies

  • Judge the star under a focused light: it should be sharp, straight and centred, not blurred or doubled.
  • Check the body colour is a genuine saturated red rather than brownish or purplish, which lowers value.
  • Ask about treatment and filling — heating can destroy the silk that makes the star, and fissure filling must be disclosed.
  • Watch the star move across the dome on video, not just in a photograph.
