April 2021 Newsletter: Best Blue Gemstones

A pure saturated blue is one of the rarest and most treasured colors in the gemstone world.

The color blue has many rich cultural associations. Blue is the color of the sky and the sea. It is often associated with depth and stability. Blue has symbolized trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. True blue means unwavering loyalty and commitment.

A light blue color is associated with peace, health, healing, tranquility, understanding and softness. Dark blue represents knowledge, power, integrity, and seriousness.

There are a number of gem varieties found in blue. But really only Sapphire is found in a pure saturated blue. Tanzanite may occasionally come close, though even the finest blue Tanzanite always has a tinge of violet. 

Most blue gemstones occur in lighter shades of blue, such as the sea blue of Aquamarine. Deeper blues may be found in Zircon and Tourmaline, but the color is rarely pure, usually with a green secondary hue. Some blue gems, such as Blue Topaz, have been heavily treated to produce the blue color. Apatite, a softer gem (5 on the Mohs scale) can be found in an intense blue or greenish-blue hue.

In cabochons, the rare Gem Silica from the Inspiration Mine in Arizona has a vivid turquoise color with good translucency. Other blue gems include Benitoite, Kyanite and Iolite.

Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

Thanks for your article about Gem Silica, they are really beautiful gems. Could you explain the difference between these Gem Silica and the Chrysoprase? MT, Canada

Gem silica and Chrysoprase are both forms of chalcedony or microcrystalline quartz. They have the same basic chemical composition (silicon dioxide) and the same hardness (7 on the Mohs scale). Chrysoprase is typically apple-green and is colored by traces of nickel. Gem Silica, colored by traces of copper, tends to be a vivid greenish-blue or bluish-green. Gem Silica is more expensive because it is a much rarer gem. But you'll notice a wide price range in Gem Silica, with the highly translucent specimens costing more. Chrysoprase, by contrast is mined in large quantities in Australia and can be found in quite large sizes at very reasonable prices.
