Topaz Buying Guide - What factors to look out for when shopping

Buy Topaz Gems

Color is king when buying any colored gemstone but what else should you consider? Size, shape, price, and clarity are just a few of the features to bear in mind.

Color

As with all colored gemstones, color is the most important factor in evaluating Topaz. Naturally, Topaz is usually colorless, light yellow or brown but can be found in many colors. The most popular and most common is blue - London Blue, Swiss Blue and Sky Blue - due to various treatments. The most expensive color for Topaz is the golden hue of Imperial Topaz. Clear Topaz can make a very affordable substitute for diamonds.

Clarity

Most faceted Topaz gemstones are at least eye-clean - that is no visible inclusions or blemishes within the stone. As it is readily available and quite affordable, there is no need to buy Topaz with poor clarity. Untreated Imperial Topaz may have some inclusions but remains valuable because of its rarity.

Carat

Generally, Topaz is one of the largest gemstones on the world market with examples of over 5 or 10 carats being quite common and found at very reasonable prices. Except for the very rare Imperial Topaz, the price per carat is quite similar no matter how big the carat size.

Cut / Shape

Topaz gemstones of all colors can be found in every type of standard gemstone shape from the common oval, round and pear outlines to the more fancy carvings. The availability of regular supplies and large carat sizes mean cutters are willing to sacrifice material to create the cut and shape they desire.
