Product Story

Deep London Blue Topaz meets crisp Art Deco geometry in this elegant 9ct white gold pendant.

At the centre sits a long octagonal London Blue Topaz, its rich blue colour framed by clean architectural lines and topped with two baguette-cut diamonds. The contrast between the saturated gemstone and sharp diamond accents gives the pendant a refined Deco character without making it feel overly formal.

The elongated proportions draw the eye beautifully down the neckline, while the cool white gold keeps the whole piece feeling crisp and contemporary.

Supplied with a 16–18 inch adjustable 9ct white gold chain and part of The House of Gemstones.

Why We Love It

We love the balance between colour and structure.

The long octagonal cut gives the London Blue Topaz a strong, graphic presence, while the baguette diamonds echo that geometry and add just enough brightness above the stone. Nothing feels overworked — the design is clean, elegant and very gemstone-led.

It’s exactly the kind of piece that feels distinctive on its own but still easy enough to wear regularly.

Why We Treasure Topaz

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.

Natural rough topaz crystal

Nature’s Artistry

Topaz commonly forms as well-defined prismatic crystals in pegmatites, high-temperature veins and cavities within igneous rocks.

Caring for Topaz

Clean topaz with lukewarm water, mild soap and a soft brush. Avoid sudden temperature changes, steam cleaning, ultrasonic cleaning and sharp knocks.

Although topaz has a Mohs hardness of 8, it has perfect basal cleavage and may split if struck sharply in the wrong direction.

The Rarest Topaz Colours

Imperial Topaz

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.

Origins and Character

Pakistan

Known for attractive pink, champagne and colourless crystals.

Understanding Treatment

How Blue Topaz Gets Its Colour

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.

Natural Colour

Topaz may naturally occur in colourless, yellow, orange, pink, brown and pale blue tones.

Irradiated & Heated

This accepted treatment is commonly used to produce Sky, Swiss and London Blue topaz.

Coated

Some topaz receives a surface coating to create unusual colours and must be disclosed.

Laboratory-Grown

Synthetic topaz exists but is much less common in jewellery than treated natural topaz.
