Quality

Naturally occurring rich Blue Topaz is rarely found in the market. The colourless, pale yellow or blue variety of topaz is irradiated to produce deeper shades of Blue Topaz. It’s a well-known fact and is accepted wholeheartedly at the international level.

• Colour
  Blue Topaz colour is one of the major quality determining factors. It ranges from the lightest sky blue to darkest inky blue with a hint of green. Amongst the traders, Sky Blue Topaz, Swiss Blue Topaz and London Blue Topaz gemstones are most popular. The selection of colour tone depends on the personal preference, but purity and uniformity should be taken into consideration. Usually, the deeper shades are considered more valuable.
• Clarity
  Absolute clarity is the standard for Blue Topaz gemstone. Because the stone is light in colour, inclusions (liquid inclusions and minerals) can be easily spotted from naked Eyes. Therefore, the Eye clean Blue Topaz with good transparency and minimum visible flaws are considered best for purchase.
• Cut
  Natural Blue Topaz crystals are faceted to show off the clarity and brilliance. Considering the Blue Topaz hardness, good availability and affordable prices, Blue Topaz rough is often faceted into deep striking cuts and unusual shapes to form gems that shimmer well when held in the light.

Origin
Topaz mines are located throughout the world, though the finest grade Blue Topaz raw stones are mined in Brazil, Sri Lanka, Pakistan, USA, Burma (Myanmar), Russia, China and Nigeria etc. Currently, the Brazilian Blue Topaz gemstones are quite popular and easily available in the gemstone industry.

Blue Topaz Price

Due to its huge production, Blue topaz wholesale prices have decreased substantially in the past few decades, down to a few dollars. Blue Topaz value depends on its colour, clarity, cut and carat weight. Currently, Blue Topaz stone price in India ranges between Rs..150 per carat to Rs…1100 per carat and plus, depending upon the quality grade. Its prices in other countries such as the UK, US and UAE etc. may vary significantly because of the variation in demand and supply cycle.

• Colour
  As per the trade rule, the more intense, uniform and deeper is the colour, higher is the Blue Topaz gemstone price. This could be the reason why London Blue Topaz value remains the highest in the market.
• Clarity
  The Eye clean Blue Topaz crystals with excellent transparency and luster are considered most sought-after for astrological as well as jewellery purposes. Natural Blue Topaz stone value drops dramatically for highly included pieces with poor transparency.
• Cut
  Blue Topaz is quite a versatile gemstone which is found in a great variety of shapes including, oval, round, square, heart, trillion, pear, rectangular cushion and many more. Generally, Blue Topaz cost increases for gems in fancy shapes with deeper cuts as their cutting process involves more wastage of the rough. Round and oval Blue Topaz are relatively cheaper because they retain maximum weight.
• Carat weight
  Due to the sufficient availability of large size Blue Topaz, Blue topaz price per carat increases linearly with increase in carat weight. However, exceptions do exist. Some strongly coloured Blue Topaz in exclusively shapes and sizes may command a higher premium.
