Gemstone profile and identification guide
Locality plays an important role in how Pink Tourmaline is understood in the gem trade. Collectors and lapidaries comparing similar stones often come to it for different reasons, but identification still comes back to pink body colour, 7 Mohs hardness, and vitreous lustre.

Did you know? Pink Tourmaline is commonly associated with material from Brazil, though the broader trade may draw on multiple localities.

Name: Pink Tourmaline
Scientific classification: Cyclosilicate (Tourmaline Group)
Hardness: 7.25 Mohs
Transparency: transparent
Lustre: vitreous
Crystal system: Trigonal
Primary colour: Pink
Secondary colour: Not specified
Colour family: Reds & Pinks
When separating Pink Tourmaline from similar-looking stones, pay attention to the combination of 7 Mohs hardness, vitreous lustre, and hexagonal crystal structure. Colour on its own is not enough; use hardness and lustre alongside hue to rule out obvious lookalikes. Useful side-by-side comparisons include Tourmaline, Green Tourmaline, Black Tourmaline.

Common inclusions: Growth tubes, liquid inclusions, and color-zoning features
Geological environment: Pink Tourmaline occurs in Boron-rich granitic pegmatites and associated hydrothermal systems. Its Trigonal structure reflects the pressure-temperature conditions of those host rocks, with notable occurrences in Brazil, Afghanistan, Nigeria, Mozambique, Madagascar.
Principal mining regions: Brazil, Afghanistan, Nigeria, Mozambique, Madagascar
Important commercial sources: Commercial gem tourmaline is supplied mainly by Brazil and East Africa, with Afghanistan important for some varieties
Historical significance: Tourmaline has become a cornerstone of modern colored-gem trade due to wide color diversity.
Common treatments: Heat treatment is used for some colors; other treatments vary by variety and source lot.
Synthetic or imitation forms: Glass and assembled imitations exist; synthetic true tourmaline is not common in jewelry trade.
Common look-alikes: tourmaline, green tourmaline, black tourmaline
Jewellery uses: Pink Tourmaline is used chiefly for Best for jewellery and display pieces where colour, pattern, or internal effect matters more than maximum wear resistance.. In the trade it is commonly fashioned as faceted stones, calibrated cuts, and higher-clarity collector pieces, with Mohs hardness 7.25 guiding suitable jewellery applications.
Care recommendations: Pink Tourmaline should be cleaned with lukewarm water, mild soap, and a soft brush. At Mohs 7.25 in the Trigonal system, avoid steam cleaners, harsh chemicals, and high-impact wear. Store separately from harder gems to minimise abrasion and edge wear.
