Frequently asked questions about tourmaline
What is black tourmaline used for and what is its meaning?
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 its shine. On the metaphysical level it is attributed the role of a "protection stone" that absorbs or neutralizes 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 an untreated natural gemstone, ready to wear loose or set.
How do I know if a tourmaline is natural and authentic?
A natural tourmaline shows internal inclusions characteristic of its formation, pleochroism (it changes tone depending on the angle of light) and, in varieties such as watermelon tourmaline, a real green-to-pink color transition. The most reliable way to confirm it is with a professional gem tester. At Gold Shield we verify every 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 one-of-a-kind natural gemstones, each piece has its own price based on weight and quality. Check the exact value of each available gemstone directly on its page at goldshield.com.mx.
Where can I buy certified natural tourmaline that ships to the USA?
At Gold Shield (goldshield.com.mx). We are a Mexican jeweler specialized in untreated one-of-a-kind natural gemstones, each one verified with a professional Presidium tester. We do custom settings in 10k, 14k or 18k gold, or in .925 silver, completely by hand. We have verified reviews on Judge.me and we ship to Mexico and the United States. You can see the available tourmalines (black, green, pink, watermelon and more) with their weight and price on our site.
Can tourmaline be set in a ring or pendant?
Yes. Tourmaline has suitable hardness 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 measure 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 impacts 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 chemicals or perfumes. With basic care, a set tourmaline keeps its shine and color for many years.
