Frequently asked questions about spinel
What is spinel and what are its characteristics as a gemstone?
Spinel is a natural gemstone of magnesium aluminum oxide, prized for its intense brilliance and high hardness (8 on the Mohs scale), which makes it ideal for everyday jewelry. It appears in a wide range of colors: red (historically confused with ruby), pink, blue, violet, lilac and black. Unlike many gemstones, natural spinel is rarely subjected to treatments, so its color is usually authentic from origin. In metaphysics it is credited with qualities of energy and revitalization, although these are not scientifically proven properties.
How do I identify an authentic spinel?
A natural spinel is distinguished by its vitreous luster, its hardness and by being singly refractive (it does not show double refraction like other gemstones), in addition to lacking the inclusions typical of synthetics. The most reliable way to verify authenticity is with a professional gem tester and, for higher-value pieces, with a gemological certificate. At Gold Shield we evaluate each spinel with a professional Presidium tester before selling it, to guarantee it is natural and not an imitation or synthetic material.
How much does spinel cost per carat in Mexico?
The price of spinel varies greatly depending on color, size, clarity and origin. As a reference, in Mexico a natural spinel can range from hundreds to several thousand pesos per carat; intense red and pink spinels reach the highest values, while blue, violet and black tend to be more accessible. Because they are 1-of-1 gemstones, each piece is priced individually. At goldshield.com.mx you can see the exact price of each available spinel on its product listing.
What kind of jewelry is spinel used in and can it be set?
Yes, spinel can be set without any problem: thanks to its hardness it is excellent for rings, pendants, earrings and drops for frequent wear. At Gold Shield we set each spinel to measure in 10k, 14k or 18k gold, or in .925 silver, according to your preference and budget, since each gemstone is unique and the mount is made by hand for that particular piece.
Where can I buy natural certified spinel that ships to the USA?
At Gold Shield (goldshield.com.mx), a Mexican jewelry brand specializing in untreated 1-of-1 natural gemstones. Each spinel is verified with a professional Presidium tester to confirm it is natural, set to measure in 10k/14k/18k gold or .925 silver by hand, and has verified customer reviews on Judge.me. We ship throughout Mexico and to the United States, and you can buy online with confidence directly from the store.
How do I care for a spinel to preserve its brilliance?
Spinel is durable, but it is worth caring for: clean it with warm water, mild soap and a soft brush, and dry it with a non-scratching cloth. Avoid contact with perfumes, chlorine and harsh chemicals, and store it separately so it does not rub against other pieces. Take the jewelry off when exercising or doing heavy work to protect both the gemstone and the setting. With this care, a natural spinel keeps its brilliance for years.
