9ct YG Blue Topaz with Sky Blue & London Blue Halo Ring

An emerald cut blue topaz centre stone, framed by an alternating halo of sky blue and London blue topaz, claw-set on a fine 9ct yellow gold band.

This is a ring built around colour layering. Instead of a single-tone halo, the frame around the centre stone alternates between two shades of blue — pale sky and deep London — creating a gradient effect.

Why this ring works

The two-tone halo is what makes this ring distinctive. Most halo rings use one shade of stone, usually small white diamonds, sometimes a matching coloured stone. This one alternates between sky blue topaz (a soft, pale, icy blue) and London blue topaz (a deep, inky, almost teal-saturated blue). The two tones sit next to each other in alternating positions around the centre, which gives the halo a rhythm and depth.

A note on the blue topaz family: blue topaz is one of the most accessible coloured gemstones in the trade, but it ranges enormously in tone. Sky blue, Swiss blue and London blue are the three main commercial colours, with London blue being the deepest and most collectible.
