Blue Topaz Guide

There is perhaps no gemstone more worthy of our times than blue topaz. Blue topaz celebrates the intellect, alleviates anger and sadness and provides light in places of darkness. It’s the gemstone of abundance and good health, and it looks just as good with a ball gown as it does business attire.

What is a blue topaz?

Blue topaz is a coloured variety of the gemstone topaz. It’s mined in the USA, China and Russia, with the largest specimens found in Brazil. Topaz comes in a diverse range of colours, from charming pinks to rich browns. Each shade is dazzling in its own right, but the coveted blue topaz has proven to shine brighter than the rest and is a precious favourite of gemstone lovers. It’s important to note that topaz is rarely blue in its natural form, and most blue topaz on the market has been enhanced to bring out the brilliant blue. Blue topaz is December’s birthstone, and it’s traditionally given on 16th wedding anniversaries.

What to Look for in Blue Topaz

Vibrancy of colour plays the biggest role in the value of blue topaz. Clarity and a masterful cut should also be taken into consideration. This birthstone is easy to find in large sizes, so judging blue topaz by carat size (weight) alone won’t necessarily mean it’s of better quality.

COLOUR
Gemstone colour is perhaps the most important aspect of a gemstone. Deeply saturated blue topaz fetches a higher price tag than lighter shades. Popular colour variations of blue topaz include:
London topaz:
Top-shelf London topaz is a spectral dark grayish-blue, evoking images of Big Ben cloaked in morning fog
Swiss topaz:
Swiss topaz is a stunning bright blue with a gorgeous lustre that sets it apart from other shades of blue topaz
Sky blue topaz:
This pale blue topaz captures the glow of the heavens and will delight anyone who enjoys delicate colours and cloudless skies.

CUT
Part of the beauty of these treated gemstones is their uniformity of colour. Because of their consistent saturation and remarkable clarity, blue topaz gems make a stellar choice for any shape and gemstone cut, including artistic fantasy cuts. Topaz crystals form in an elongated shape and work especially well in oval, pear and emerald shapes.

CLARITY
Topaz is a Type 1 gemstone, which means the gems for sale — including the topaz we offer — are almost completely free of inclusions, or flaws, that can be seen with the naked eye. This level of gemstone clarity makes blue topaz an “eye-clean” gemstone.
Learn About Clarity
SIZE (CARAT)
Unlike diamonds, which are measured by carat weight, a more accurate way to assess the size of gemstones, including blue topaz, is by its diameter in millimeters. This gives you a greater picture of what the gem will look like in its setting.
Learn About Size
ENHANCEMENT
Naturally blue topaz with vivid saturation is an anomaly. Most topaz is found colourless or in diluted shades of yellow, pink, blue or grey. The jewels undergo a treatment of irradiation and heat to produce the beautiful colours that blue topaz is known for. These gemstone enhancements are permanent and won’t fade over time.

Hardness & Wearability

Blue topaz has a Mohs hardness rating of 8, meaning it isn’t as indestructible as a diamond and may be prone to chipping or scratching. But if you wear blue topaz with care, it can withstand everyday wear and tear.

Choosing the Right Blue Topaz Jewellery

Blue topaz is a reasonably priced gemstone that rivals even the most expensive sapphires and aquamarines with its scintillating shades of blue. It looks striking whether it’s a subtle Sky Blue gem set in a gold ring or a lustrous London Blue necklace decorating your décolletage.
