Blue Topaz Gives Bright Outlook

Blue Topaz comes in several hues of blue. Whatever it's color, Blue Topaz is a popular gemstone and not only makes beautiful jewelry, but also has a variety of interesting legends.

Being a quartz crystal, Blue Topaz is usually colorless before being transformed through irradiation into its blue color. The clear quartz crystals are irradiated to draw out the blue hues, then heat treated to seal in the color. The hue of blue depends on the type of radiation exposed to the quartz crystals.

Bombarding topazes with neutrons in a nuclear accelerator changes the color to the deep green-blue or gray-blue known as London Blue Topaz. Exposing the topaz crystals to electrons in a linear accelerator produces the most common color of Blue Topaz - Sky Blue Topaz. To produce Swiss Blue or Electric Blue Topaz, the quartz is bathed in a combination of both kinds of radiation. After almost a year of "rest," the radiation levels are cool enough so that they can be worn by consumers.

Since most quartz crystals have low value, there's really no incentive to create synthetic stones. Mystic Blue Topaz is created by vapor coating quartz crystals with titanium particals to produce a rainbow coloration of red, green, and teal hues. Since this effect is produced by a thin coating of titanium, Mystic Blue Topaz is extremely fragile and must be handeled with the greatest of care.

Even though Blue Topaz has a very unusual production technique, it performs wonderfully as a gemstone because it polishes up beatifully and has a very high refractive index. Having a Moh's Scale of 8 makes Blue Topaz one of the hardest gemstones and also makes it very durable and ideal for jewelry.

Blue Topaz is said to aid in the regulation of the heart, promotes glandular health, reduces fever and inflammations such as arthritis. On the other hand, the color of Blue Topaz is said to aid in meditation, discernment, and forgiveness. The calming effect of its blue color is believed to help its wearers let go of their anger and fosters forgiveness and reconciliation that leads a calmer and more fulfilling life.
