Topaz Colors - Red, Blue, Pink, Violet, Green and More!

Topaz is a stunning and versatile gemstone known for its wide range of vibrant hues. When people ask, "What color is topaz?" the answer can vary, as this gemstone is found in shades from golden yellows to blues, pinks, and even colorless forms. The topaz color can greatly influence its appearance and value. Topaz can be found in many colors including yellow, orange, brown, red, blue, pink, violet and green. We stock almost every variety of topaz gemstones in our online store.

Colorless topaz is fairly common and is sometimes given a brilliant cut and sold as a substitute for diamond. Indeed, one of the most famous topaz gemstones in the world is a colorless topaz that was originally thought to be a diamond. It is a 1,680 carat stone known as the Braganza Diamond, owned by the royal family of Portugal. The gem apparently disappeared after the death of King John VI in 1826.

The most frequently seen colors of natural topaz include pale yellow, brown, and gray, with occasional pastel tones of light green, violet, and pink. To enhance their vibrancy, these colors are often treated. Blue topaz stands out as the most favored hue, consistently ranking as the top-selling jewelry stone in the USA. Its exceptional brilliance, luster, and clarity, all at an appealing price point, make it a fantastic value.

However, blue topaz occurs very rarely in nature, and then only in a very pale blue. The striking shades of blue topaz you'll find for sale are the result of widely-used enhancement techniques, usually involving irradiation followed by heating. These techniques are well-regulated, permanent and stable. Irradiation results in a deep blue with a slight green tone, known as London blue; a highly saturated medium blue known as Swiss blue; and a bright light-blue known as sky blue.

The most valuable topaz color is an orange to pink color known as imperial topaz. The exact color for imperial topaz is not well-defined, so a wide range of golden orange, peach and pink colored topaz is sold under this name. Some light-pink topaz gems are the result of heat treatment.

Bright pink topaz is the result of another enhancement technique - a high-tech process known as thin-film deposition. The technology involves depositing an extremely thin metallic layer only a few microns thick. This layer changes the optical properties of the material.

The thin metallic film is applied to the pavilion (bottom half of the gem), so that the interesting color effects are reflected through the crown. The film is molecularly bonded to the stone, effectively becoming part of the topaz. The range of colors is almost limitless, and include bright pink, electric blue and prismatic mystic topaz. Mystic topaz is popular for its unusual, striking colors.
