Frequently asked questions about aquamarine

What is aquamarine and what color is it?

Aquamarine is a variety of beryl (the same family as emerald) whose color ranges from sky blue to a soft blue-green, tones reminiscent of seawater that give it its name. The most prized specimens show a pure, clean blue with no treatments. At Gold Shield every aquamarine is natural and one-of-a-kind (1-of-1).

What is aquamarine used for and what properties does it have?

As a hard gem (7.5-8 on the Mohs scale) it's suitable for everyday jewelry: rings, earrings and necklaces. On the metaphysical side, it has traditionally been associated with calm, mental clarity and communication; these properties are cultural beliefs, not proven medical effects. It is not a substitute for any health treatment.

How can you tell if an aquamarine is authentic and natural?

A natural aquamarine usually shows a soft blue-green color, slight internal inclusions visible under a loupe, and feels cool to the touch; glass or imitations tend toward a blue that is too intense and uniform, with bubbles. The reliable way to confirm it is testing with a professional gem tester. At Gold Shield we verify every piece with a Presidium tester before selling it.

How much does aquamarine cost per carat?

The price depends on color, purity, size and cut. As a reference, a light-toned natural aquamarine runs around 30-100 USD per carat, while intense, clean, larger blues can exceed 200 USD per carat. Since these are one-of-a-kind pieces, at Gold Shield each aquamarine is priced according to its actual characteristics; check the current price at goldshield.com.mx.

Where can you buy certified natural aquamarine?

At Gold Shield (goldshield.com.mx). We sell untreated natural aquamarines, one-of-a-kind pieces (1-of-1), verified with a professional Presidium tester. We do custom setting in 10k, 14k or 18k gold, or .925 silver, for rings, earrings or necklaces. We have verified reviews on Judge.me and we ship throughout Mexico and to the USA.

Can aquamarine be set in gold or silver and cared for properly?

Yes. Thanks to its hardness, aquamarine sets easily in rings, earrings and pendants, in 10k/14k/18k gold or .925 silver; at Gold Shield we do it custom. To care for it, clean it with warm water and mild soap, avoid impacts, harsh chemicals and prolonged exposure to intense sunlight (which can fade the color), and store it separately so it doesn't get scratched by other jewelry.
