Topaz

Topaz has been an important gem for thousands of years.  There are references to topaz in ancient texts from various cultures.One of the characteristics of topaz that makes it desirable as a gemstone is that it is relatively hard or resistant to scratches.  It is however, brittle and if not set properly can split  if  hit in a certain way..  Topaz comes in a variety of colors: blue, yellow, brown, pink and colorless, with blue being the most widely known and commonly used in jewelry.

6 Things You Should Know Before Buying a Topaz

1. Color: Topaz comes in a range of colors.  The color affects the value of the topaz stone, both in how rare the color is and how intense and attractive the color is. 
2. Cut: The value of a topaz gemstone is affected by how well it is cut.  A perfect cut means that the topaz gives the maximum amount of sparkle.  The quality of the cut can make a huge difference in the price of the topaz.  
3. Clarity: Most faceted topaz gemstones that are used in jewelry have pretty good clarity.  A topaz with poor clarity will look cloudy and will be worth considerably less. 
4. Size:  Topaz is often available in large sizes (over 10 carats).  Size does affect the value of a topaz gemstone, but not as much as the other quality indicators.  See how different topaz sizes compare and
5. Treatments and Fakes: A very large determiner of the value of a topaz is whether and how it has been treated.  There is increasing debate and controversy.  Topaz with certain treatments have even been banned by governments for being unsafe.  It is important to understand topaz treatments, as well as possible imitations before buying one.  
6. Meaning and Symbology: Citrine embodies powerful symbolism and healing energetic properties.
