Small Pink Topaz Gemstone Huggie Earrings 1.4 cm Diameter

Measure 1.4 cm across The stones measure as topaz on my gem tester. Gem testers don’t differentiate between natural and lab created but from close examination I say natural topaz. I expect the earrings to be gold if they contain real gemstones although I can’t find any hallmarks but the backs are open work crowns which could have some significance. Crowns are a hallmark on jewelry of gold purity.
