Blue Topaz

Blue Topaz is the most popular colour in today’s jewellery marketplace. It is sold in a broad range of blue colours, starting from a pale blue with a light tone and saturation, all the way to a deep blue with a moderate to dark tone and saturation.

Blue topaz is very attractive, inexpensive, and a favourite colour of the jewellery customer. These characteristics drive the popularity of blue topaz.

Before 1970 most of the topaz in low to moderate price jewellery was yellow to brown in colour. Natural topaz with an attractive blue colour was rare and very expensive. As a result it was seldom seen in jewellery. Today’s blue topaz is a product of gem treatment.

In the early 1970s, gem treatment experiments revealed that much of the abundant and inexpensive colourless topaz could be converted into blue topaz. The colourless topaz was first treated with high-energy electron or gamma radiation and then heated to a beautiful blue colour. Treaters learned to vary the treatment procedure to yield topaz in a wide range of blue colours.

The radiation used to treat topaz consists of a beam of subatomic particles. These tiny particles enter the topaz crystal at high velocity and have the ability to knock electrons out of their orbits or cause other damage to the crystal lattice. These defects change the way that light travels through the crystal and can change the wavelengths of light that are absorbed. The result can be a change in the colour of the topaz as perceived by the human eye.

Mainly Two varieties of treated blue topaz have come into popularity. These are known as “Swiss Blue” and “London Blue” topaz. Swiss Blue is a bright blue topaz lighter in tone and saturated moderately. London Blue is a dark blue topaz with a moderate to dark tone and saturation.

These two colours give jewellery buyers a choice of two blue colours. London Blue Topaz is the current market favourite. It is only slightly more expensive than Swiss Blue topaz.
