9Ct Gold Marquise Cut Opal & Sapphire necklace

A marquise shape carries a vintage-inspired confidence, and this late-1970s pendant wears it well. The opal is cut to that pointed oval — elegant, a touch theatrical — with a cluster of deep blue sapphires gathered beneath for contrast. It sits neatly whether your collar is open or high, and at just 1.4g it's genuinely light for regular wear. I find the marquise flatters most necklines; it draws a line rather than a dot, which lends a little length. Crafted in London in 1979 and hallmarked 375 for 9ct gold. A characterful piece with a defined, period profile.
