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 one that forms the ruby. 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 one-of-a-kind (1-of-1) untreated stones. Traditionally it is associated with qualities of wisdom, calm and protection, though 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 the diamond), cool 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 review by a gemologist. At Gold Shield we verify every gemstone with a Presidium tester before selling it, and each piece is one-of-a-kind.

What is the price of a natural sapphire per carat?

The price depends on the color, saturation, clarity, size and origin. As a general reference, a commercial-quality natural sapphire can range from a few hundred to several thousand pesos per carat, and intense blue or fine pink sapphires reach much higher prices. Because they are natural one-of-a-kind (1-of-1) stones, each sapphire is quoted individually. Write to us for an exact quote on the stone you're interested in.

Can a sapphire be set in an engagement ring?

Yes. Sapphire is one of the most popular gems for engagement rings because of its hardness (9 on Mohs), which makes it very resistant to daily wear, and for its beauty. Blue sapphire is the classic, but pink sapphire is also trending. At Gold Shield we set your natural sapphire to measure 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?

Because of its great hardness, sapphire is one of the easiest gems 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 doesn't scratch other softer pieces. Take it off when using harsh chemicals or doing heavy work. With basic care, a natural sapphire keeps its brilliance for generations.
