More than forty years of craftsmanship have led us to our newest chapter,

tradition of jewellery, watch and clock expertise.
Deep blue topaz meets warm yellow gold in a sleek, contemporary half-hoop design.
Crafted in 9ct yellow gold, these earrings feature a sequence of elongated London Blue Topaz gemstones set into a gently curved profile. The emerald-style cuts give the stones a clean architectural look, while the rich blue colour creates a beautiful contrast against the polished gold. Gecko lists the design as Elongated Topaz Half Hoop Earrings in 9ct Gold.
They’re compact enough for everyday wear, but the depth of colour gives them far more presence than a plain gold hoop.

Why You’ll Love Them
We love how modern these feel.
The stepped arrangement of elongated topaz creates a strong geometric rhythm around the ear, while the half-hoop silhouette keeps the design neat and wearable. The deep London Blue Topaz looks especially striking against yellow gold, giving the earrings a rich but very polished finish.
They also pair perfectly with the matching elongated topaz pendant.

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.
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.
Understanding Topaz Colour
A Gemstone of Many Colours

Imperial Topaz
The most prized range, typically orange, pinkish orange or warm reddish orange.

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.

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.
Marcus Tempus Gemstone Selection
How We Select Our Topaz
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.
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.
