Product details
Topaz is a very popular gemstone. Gem quality topaz most commonly occurs in nature as a colourless crystal. When cut as a gemstone these colourless specimens generally have the lowest value. A significant amount of natural topaz also occurs in a colour range spanning from yellow to brown. Small amounts of natural blue and pink topaz are found but most have been treated.

GIA CLARITY SCALE FOR COLOURED GEMS IS USED
All gems sold by top drawer are listed as described by our suppliers, however as the majority of gem stones have undergone some form of enhancement, one should always assume treatments. For some varieties there is little difference between the values of enhanced, treated and natural gems. Exceptions such as ruby, sapphire and emerald,command high prices when untreated and are extremely rare. ( Be sceptical of claims that any of the above are untreated, especially on the internet. )
Buyers should also be aware that most of the quartz family of gems on auction such as amethyst, citrine and ametrine are probably hydrothermal and/or have been subjected to heat or irradiation. This applies to topaz as well, which in addition is sometimes coated. In this, the lower end of the market, these treatments and processes do not markedly affect the value, look or durability of the gem, therefore the high cost of lab certification can not be warranted. However, if you are purchasing high end gems for investment purposes, you should have your gem lab certified. Certificates provided by the seller are generally not worth the paper they are written on and should be regarded with suspicion.
