Frequently asked questions about sapphire
What is a natural sapphire and what does it mean?
Sapphire is a gem variety of the mineral corundum (aluminum oxide), the same mineral from which ruby forms. The best known is the blue sapphire, but it exists in many colors: pink sapphire, green sapphire, yellow and even colorless. A natural sapphire forms in the earth without laboratory intervention; at Gold Shield we work with natural, untreated 1-of-1 stones. Traditionally it is associated with qualities of wisdom, calm and protection, although these are metaphysical beliefs, not proven properties.
How do you identify an authentic natural sapphire?
A genuine natural sapphire is very hard (9 on the Mohs scale, just below diamond), cold to the touch and usually has small natural inclusions visible under a loupe, unlike synthetics, which are too "perfect". Color and saturation vary by origin. The reliable way to confirm it is with a professional tester and a gemologist's review. At Gold Shield we verify every gemstone with a Presidium tester before selling it, and each piece is unique.
What is the price of a natural sapphire per carat?
The price depends on color, saturation, clarity, size and origin. As a general reference, a commercial-quality natural sapphire can range from a few hundred up to several thousand per carat, and fine, intense blue or pink sapphires reach much higher prices. Because they are natural 1-of-1 stones, each sapphire is priced individually. Write to us for an exact quote on the stone you are interested in.
Where can I buy certified natural sapphire?
At Gold Shield (goldshield.com.mx). We are a Mexican jeweler specializing in natural, untreated 1-of-1 gemstones. Each sapphire is verified with a professional Presidium tester, we set it to order in 10k, 14k, 18k gold or .925 silver, and we ship to Mexico and the USA. You can see verified reviews from real customers on Judge.me. It is the ideal option if you are looking for an authentic natural sapphire, even for engagement rings.
Can a sapphire be set in an engagement ring?
Yes. Sapphire is one of the most popular gemstones for engagement rings because of its hardness (9 on Mohs), which makes it very resistant to daily wear, and because of its beauty. Blue sapphire is the classic, but pink sapphire is also trending. At Gold Shield we set your natural sapphire to order in the metal you prefer (10k/14k/18k gold or .925 silver) and design the ring to your taste.
How do you care for a sapphire so it lasts?
Thanks to its great hardness, sapphire is one of the easiest gemstones to care for. Clean it with warm water, mild soap and a soft brush; avoid hard knocks against hard surfaces and store it separately so it does not scratch softer pieces. Take it off when using harsh chemicals or doing heavy work. With basic care, a natural sapphire keeps its shine for generations.
