Vintage blue zircon stud earrings. These are fabulous bright blue round cut gemstones set in rex or crown style 9 carat white gold. The gemstones are a greenish-teal blue, exactly as you'd expect from blue zircons. The simple setting shows them off to their best. These studs are a good size and as such we've added large 9 carat white gold backs for an easier grip. Circa 1960s - 1970s blue zircons and setting, we've added new backs.

Stamped 375 on the scroll backs, professionally tested and assessed as 9 carat white gold throughout.

Measure approx 7.7 mm wide.

Weigh 2.1 grams together, approx 1 - 1.1 gram each.
