Sterling silver 925 necklace with pendant in natural untreated opal – 46 cm – 3.30 g Cabochon- 3.3 g - (2)

This sterling silver (925) necklace features a pendant made from natural untreated opal, set as a cabochon — a smooth, polished gem shape without facets, often used to highlight play-of-color or surface texture. Untreated opals are especially valued among collectors and jewelry aficionados because they retain their natural state without enhancements, offering an authentic connection to their geological origins.

At 46 cm, the chain length sits comfortably at an average necklace length, suitable for everyday wear or special occasions. Opals are composed of silica spheres, which diffract light to produce their signature iridescent effect. Because the stone is untreated, one can expect a genuine display of color and depth that is characteristic of quality opal.

Sterling silver provides a classic and durable setting for opals, which are softer than many other gemstones and require careful handling to preserve their beauty over time.
