Vintage opal & diamond cluster ring


A superb 1960s opal and diamond cluster ring. This particular ring is a large show-off piece with a significant proportioned head. The opal is the star of the show which we have calculated as being approximately just over 4ct. However it looks far larger thanks to being a fairly thin piece of opal. Surprisingly despite its thickness the opal has a wonderful depth of colour with good flashes of reds, blues and greens evenly spread out across the stone. This is a highly desirable property of opals.

18ct gold and platinum settings.
Unmarked. Tests indicate 18ct gold with the upper part of the pierced gallery being platinum. Being pre 1975 this would have been omitted from hallmarking legislation thanks to mixed metals being present.

Different environments give a totally different looking stone. This is the magic of opals. Twenty brilliant-cut diamonds each approximately 0.04ct giving a total carat weight of 0.80ct. Colour G/H. Clarity VS.
The head of the ring measures 23mm x 17.8mm wide and stands 11.6mm proud of the finger. The shank measures 2.5mm wide.
