Frequently asked questions about tourmaline

What is black tourmaline used for and what does it mean?

Black tourmaline (also called schorl) is one of the most sought-after varieties. On the physical level it is a natural stone highly valued for its intense color and shine. On the metaphysical level it is associated with the role of a "protection stone" and with absorbing or neutralizing negative energies, which is why many people wear it in bracelets or as a pendant; these are traditional beliefs, not proven medical effects. At Gold Shield we offer it as a natural, untreated gemstone, ready to wear loose or set.

How do you know if a tourmaline is natural and authentic?

A natural tourmaline shows internal inclusions characteristic of its formation, pleochroism (it changes shade depending on the angle of light) and, in varieties such as watermelon tourmaline, a real transition of color from green to pink. The most reliable way to confirm it is with a professional gemstone tester. At Gold Shield we verify each piece with a Presidium tester and deliver 100% natural gemstones with no artificial treatments, so you know exactly what you are buying.

How much does tourmaline cost? What is the price per carat?

The price depends on the variety, the weight in carats, the color and the clarity. As a reference, black tourmaline is the most affordable; colored tourmalines (green, pink, watermelon) go up in price; and Paraiba tourmaline is one of the most prized in the world. Because they are natural 1-of-1 gemstones, each piece has its own price according to weight and quality.

Can tourmaline be set in a ring or pendant?

Yes. Tourmaline has a hardness suitable for jewelry (around 7 to 7.5 on the Mohs scale) and sets very well in rings, pendants, earrings and bracelets. At Gold Shield we set your natural tourmaline to order in 10k/14k/18k gold or .925 silver, designing the piece around the gemstone you choose to highlight its color.

How do you care for a tourmaline so it keeps its color?

Clean it with warm water, mild soap and a soft cloth; avoid ultrasonic and steam cleaners, as well as knocks and sudden temperature changes, especially in colored varieties such as pink or watermelon. Store it separately so other pieces do not scratch it and take it off before using chemical products or perfumes. With basic care, a set tourmaline keeps its shine and color for many years.
