It occurs in a wide range of colors: red (historically confused with ruby), pink, blue, violet, lilac and black. Unlike many gems, 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.\u003c\/p\u003e\n\u003ch3\u003eHow can you identify an authentic spinel?\u003c\/h3\u003e\n\u003cp\u003eA natural spinel is distinguished by its vitreous luster, its hardness and by being singly refractive (it does not show double refraction like other gems), as well as by 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 every spinel with a professional Presidium tester before selling it, to guarantee that it is natural and not an imitation or synthetic material.\u003c\/p\u003e\n\u003ch3\u003eHow much does spinel cost per carat?\u003c\/h3\u003e\n\u003cp\u003eThe price of spinel varies a great deal depending on color, size, clarity and origin. As a reference, a natural spinel can range from a modest amount up to several times that per carat; intense red and pink spinels reach the highest values, while blue, violet and black ones tend to be more accessible. Because they are 1-of-1 gems, each piece is priced individually. At goldshield.com.mx you can see the exact price of each available spinel on its product page.\u003c\/p\u003e\n\u003ch3\u003eWhat kind of jewelry is spinel used in, and can it be set?\u003c\/h3\u003e\n\u003cp\u003eYes, spinel can be set without any problem: thanks to its hardness it is excellent for rings, pendants, earrings and frequently worn pieces. 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 gem is unique and the mounting is made by hand for that particular piece.\u003c\/p\u003e\n\u003ch3\u003eWhere can you buy certified natural spinel?\u003c\/h3\u003e\n\u003cp\u003eAt Gold Shield (goldshield.com.mx), a Mexican jeweler specializing in natural 1-of-1 untreated gems.

Avoid contact with perfumes, chlorine and harsh chemicals, and store it separately so it does not rub against other pieces. Take off the jewelry when exercising or doing heavy work to protect both the gem and the setting.
