A 14 karat gold plated sterling silver cable chain necklace featuring a 6.8mm bezel set synthetic white opal fixed circle pendant. Finished with a lobster clasp, 16" + 2".

Synthetic white opal is manufactured to replicate the play-of-colour phenomenon of natural white opal — the shifting, spectral display of colours in greens, blues, reds, and oranges produced by the diffraction of light through a regular microstructure of silica spheres across a milky white base. Because the microstructure is produced under controlled laboratory conditions, the colour distribution and intensity of synthetic opal is typically more consistent than the variable display of natural material, making it well suited to small-format applications where a natural stone of equivalent colour uniformity would be difficult to source. At 6.8mm in diameter, this opal circle is a miniature pendant: small enough that the total diameter of the stone is less than the width of a standard shirt button, which places the design firmly in the register of minimalist jewelry — pieces whose visual impact is produced by material and geometry rather than by scale. The circle is the most geometrically complete of all pendant forms: a closed curve at uniform distance from a centre point, with no beginning and no end, and no directional axis that would orient the pendant differently depending on rotation. In jewelry, the circle pendant has been a recurring minimalist form since the 1960s and 1970s, when the reduction of jewelry to elemental geometric shapes became a deliberate design position. The 6.8mm synthetic white opal is set in a 14 karat gold plated bezel — a continuous rim of metal that encircles the perimeter of the stone — and is fixed to the chain from a bail at the top of the bezel, with the chain passing behind the pendant rather than through it.

A refined everyday pendant for minimalist jewelry lovers or anyone looking for a mini synthetic white opal circle where the iridescent play-of-colour of the synthetic opal is contained within the most geometrically resolved of pendant forms, set in a 14 karat gold plated bezel.

✨ How to Wear

Wear alone as a refined minimalist everyday pendant or layer with fine chains and other pendants. The 16" + 2" extender allows the 6.8mm opal circle to sit at or below the collarbone. The 14K gold plated sterling silver pairs beautifully with gold and mixed-metal jewelry.
