Blue topaz

Naturally occurring blue topaz is rare, and when it does occur the color is generally pale. The blue topaz that is on the market today has been treated with radiation to deepen and set the blue tones. The process used gives very predictable results, making it possible to perfectly match the hue every time.

Until recently, blue topaz was considered the least valuable of all topaz colors, but the advent of the irradiation treatment has changed that. The stunningly clear blues that are achieved has made blue topaz one of the most popular gemstones on the market.

Blue topaz buying guide

Blue topaz comes in a range of colors. The most desired is a pure, clear robin's egg blue. When buying blue topaz, be sure to examine the stone under both natural and incandescent light. Because the stone is so light in color, inclusions show easily, but eye clean stones are not uncommon.

Be wary of unscrupulous dealers trying to pass the less expensive quartz off as blue topaz. If possible, have the stone appraised by an independent gemologist.

Blue topaz care

Like diamonds, topaz have perfect cleavage - meaning that a sharp blow from the right direction will cause the stone to split perfectly along the cleavage line. For this reason, it's important to protect blue topaz from situations where it may receive a sharp blow.

Everyday cautions

Remove blue topaz jewelry when doing house or yard work, and before applying makeup and hair spray.

Cleaning blue topaz

Clean blue topaz jewelry with a soft cloth or brush and a solution of mild dishwashing liquid and water. Soak the piece of jewelry in the solution for ten to twenty minutes, then carefully scrub with a soft toothbrush. Do not use ultrasonic or mechanical cleaners and avoid harsh chemical cleaning solutions.
