A rhodium plated sterling silver necklace featuring a 9mm x 15mm blue synthetic opal semicircle pendant. Finished with a lobster clasp on a 16" + 2" chain.

The semicircle pendant is cut entirely from synthetic opal — the semicircle form is the opal itself, not a stone set within a metal frame. The full face of the pendant is opal from edge to edge: the flat base and the curved top are both opal, and the play-of-color — the shifting spectral blues, greens, and purples that move across the surface as the viewing angle changes — covers the entire surface without interruption. The semicircle is the most reduced geometric form in this series: a flat base and a single arc, defined entirely by a straight line and one curve, with no additional elements and no symbolic associations drawn from nature or astronomy. At 9mm x 15mm, the semicircle is wider than it is tall, giving it a horizontal, landscape-oriented proportion that sits differently on the chest than the more vertical forms in the series. The wider surface area means the play-of-color is visible across a larger canvas than in the more compact star or crescent shapes. The pendant connects to the rhodium plated chain via a small bail.

A refined gift for geometric jewelry lovers, opal enthusiasts, or anyone looking for a pendant where a purely architectural form is cut entirely from colour-shifting synthetic opal.

✨ How to Wear

Wear alone as a refined everyday geometric pendant, or layer with the crescent moon and star from this series. The 16" + 2" extender allows the semicircle to sit at or below the collarbone. The rhodium plated sterling silver pairs beautifully with silver and white gold jewelry.
