The price of Tourmaline depends on its colour, variety, clarity, transparency, carat weight, cut, origin, and overall quality. Rare and vivid colours, such as fine blue or certain pink and green varieties, may command higher prices. Black Tourmaline is generally valued differently from transparent jewellery-grade varieties. Natural inclusions and colour zoning can affect appearance and value. Always check the product description for the specific stone's details and any available authenticity or gem identification documentation.

Clean Tourmaline gently using lukewarm water, mild soap, and a soft cloth or brush. Rinse carefully and dry with a soft, lint-free cloth. Avoid harsh chemicals, ultrasonic cleaners, sudden temperature changes, and prolonged exposure to extreme heat. Store separately from harder gemstones to reduce the risk of scratches. For jewellery, inspect the setting regularly and seek professional cleaning when needed.
