Where can blue topaz be found?

Though some Natural Blue Topaz can be found, it is incredibly rare and extremely expensive. Currently, stores of naturally colored topaz can only be found in Ouro Prêto, Brazil. Brazil is the the largest producer of all topaz worldwide, but it is also mined in countries across the globe.

Many high-quality blue topaz gemstones are produced by treating colorless topaz with heat radiation, which takes 3-4 years to produce the most vibrant color. All of our London Blue Topaz at With Clarity are natural gems that have been color-treated, resulting in stones with saturated color, few inclusions, and therefore higher grades. The results of this treatment are 100% natural and permanent.

Quality Factors

When purchasing a Blue London Topaz, it is important to consider several key factors in order to make the best choice for your individual style and budget. Like many other gems, you should consider the 4 Cs when purchasing topaz: cut, color, carat, and clarity.


London Blue Topaz can be cut in a variety of ways. The most popular choices for blue topaz are round and emerald. These cuts result in stunning pieces for all kinds of jewelry. Cut plays a major role in how the gem will appear in its setting, so choosing the cut that is best suited for blue topaz is essential to achieving the most incredible results.


Round-cut gemstones are a classic cut that emphasizes the natural beauty of the stone. Round-cut gems are a member of the brilliant-cut family of stones. These cuts are designed to enhance the sparkle and brilliance of a stone. Round cut has 58 facets and is considered a timeless and elegant choice, especially for engagement or wedding rings.


Emerald-cut gemstones have long, rectangular bodies that contain step-like facets. These are the most popular kind of the larger family of step-cut stones. Emerald-cut gems showcase color better than many other more complicated cuts, making them an ideal choice to enhance the beauty of blue topaz. Emerald-cut topaz can also accommodate larger gems, making them suitable for show-stopping pieces of larger jewelry.


London Blue Topaz is known for its stunning color, meaning it is critical to choose London Blue Topaz with high-quality color when selecting a gem. The color of a blue topaz should be rich and saturated. It should also be uniform and free of any visible inclusions.


Like other colored gemstones, London Blue Topaz is graded on a scale that includes gems that are classified from the highest grade to the lowest as AAAA, AAA, AA, B.


This is the highest grade for blue color topaz, but these stones are very rare and not widely available. Only 1% of gemstones worldwide meet the criteria to receive this grade.


This grade represents a high-quality stone that offers amazing color and clarity. AAA graded stones represent the top 10% of the highest quality gemstones.


This is a more affordable choice, but imperfections can sometimes be seen in this grade of the stone. Blue topaz with this rating can still be used in quality jewelry.


This grade of stone tends to be less coveted and makes up 50% gemstones.
