A deep flash of blue, framed by crisp white gold and a subtle line of diamond light.
This striking pendant centres on a 15 × 7mm long octagonal London Blue Topaz, held in a minimal four-claw setting that leaves the rich, saturated gemstone firmly in focus. Above it, a double row of pavé-set diamonds creates a refined transition into the bail, adding brightness without overwhelming the stone.
The elongated proportions and geometric cut give the pendant a distinctly Art Deco-inspired character, while the cool white gold keeps the overall look clean, contemporary and elegant.
Part of The House of Gemstones.
We love the sheer presence of the gemstone.
At 15 × 7mm, the London Blue Topaz has enough size to really show off its deep, inky colour, while the long octagonal cut gives the piece strong architectural character. The pavé-set diamond bail adds just enough sparkle at the top, creating contrast without distracting from the blue.
It feels substantial and special, but still beautifully restrained.
The House of Gemstones
Topaz is admired for its exceptional clarity, bright vitreous lustre and remarkable colour range. It can appear colourless, golden, pink, orange, red, green or blue.
Its natural brilliance and ability to form in impressive crystal sizes make it equally suited to refined everyday jewellery and dramatic statement pieces.
Nature’s Artistry
Topaz commonly forms as well-defined prismatic crystals in pegmatites, high-temperature veins and cavities within igneous rocks.Clean topaz with lukewarm water, mild soap and a soft brush. Avoid sudden temperature changes, steam cleaning, ultrasonic cleaning and sharp knocks.
Understanding Topaz Colour
The most prized range, typically orange, pinkish orange or warm reddish orange.
Warm yellow to golden brown, often displaying excellent brilliance.
Soft blush through vivid pink; fine natural material is rare.
A pale, fresh blue with a light and elegant appearance.
Bright, vivid blue with energetic saturation.
A deeper, inky blue with subtle greenish or greyish undertones.
Colourless topaz with clean transparency and understated brilliance.
The Rarest Topaz Colours
Imperial topaz describes the most desirable warm colours, including rich orange, pinkish orange and reddish orange. The finest stones combine saturation, brightness and excellent transparency.
Colour terminology can vary within the trade, so important stones benefit from careful assessment and, where appropriate, an independent gemmological report.

Understanding Treatment
Natural strongly coloured blue topaz is uncommon. Much of the blue topaz used in jewellery begins as colourless material that is irradiated and then heated to create stable blue colour.
Topaz may naturally occur in colourless, yellow, orange, pink, brown and pale blue tones.
This accepted treatment is commonly used to produce Sky, Swiss and London Blue topaz.
Some topaz receives a surface coating to create unusual colours and must be disclosed.
Synthetic topaz exists but is much less common in jewellery than treated natural topaz.
Marcus Tempus Gemstone Selection
We select topaz for colour, transparency, brilliance, cutting and overall presence. We also consider treatment disclosure and whether the gemstone is well suited to the intended jewellery design.
Marcus Tempus Bespoke
Topaz jewellery can be created around your preferred colour, gemstone shape and precious metal. Where the design allows, we can discuss Imperial, golden, pink, white or blue topaz and select a setting that offers appropriate protection.
Availability varies according to colour, treatment, shape, size and stone dimensions. Topaz has perfect cleavage, so some ring designs may require a protective setting or small design adjustments.
