Tourmaline Gemstone Beads

Frequently asked questions

• Is tourmaline real, or is it dyed?

  Tourmaline is a single-crystal silicate with characteristic transparency or translucency. Dyed glass, dyed agate, and composite material are sometimes sold as "tourmaline" or "watermelon tourmaline" in the cheap-bead market — those are different categories. Real watermelon tourmaline shows the pink-to-green color transition along a single crystal axis; dyed glass does not. Material category should be disclosed — ask if a strand doesn't specify whether it's natural tourmaline or composite.
• Is tourmaline heat-treated?

  Often, yes. Pink (rubellite), green (verdelite), and blue (indicolite) tourmaline are routinely heated at 600–700°C to lighten dark material or to clean color tones. The treatment is permanent, stable, and accepted across the global trade. Watermelon tourmaline is typically untreated because the visible color zoning is the buying decision. Black tourmaline (schorl) and chrome tourmaline are almost never treated. Treatment status (Natural or Heat-Treated) should be disclosed — ask before buying if a strand doesn't specify.
• Is rubellite the same as pink tourmaline?

  Yes — *rubellite* is the trade name for saturated red-pink tourmaline. Lighter pink elbaite is generally just called "pink tourmaline." There is no hard chemistry boundary; the distinction is color saturation.
• What is watermelon tourmaline, and is it natural?

  Watermelon tourmaline is a single elbaite crystal that grew with a pink core and green rim, sliced perpendicular to the crystal axis to display the color zoning. The zoning is natural — it formed during crystal growth as the trace-element chemistry of the surrounding fluid changed. Watermelon is typically untreated. The zoning has to be both attractive and well-positioned for the slice to show, which is why fully-zoned watermelon is less common than off-zoned material.
• What's the difference between Paraíba and other blue-green tourmaline?

  Paraíba tourmaline is copper-bearing tourmaline, producing a uniquely vivid neon blue-green that other tourmaline copper-free chemistries cannot match. The original deposit is in Paraíba State, Brazil (1989); the trade name has since broadened to include copper-bearing tourmaline from Mozambique and Nigeria, which is similar in appearance but typically more available and lower-priced than Brazilian Paraíba. Deposit / origin should be disclosed when known — ask if a strand doesn't specify. Bead-grade Paraíba is rare; most beads in this color range are African copper-bearing tourmaline.
