Designed and signed by Heng Ngai, these earrings feature a large dangling smoothed teardrop-shaped turquoise gemstone mounted in sterling silver. Each ear loop has a built-in non detachable backing. On one side of each earring base is hallmarked 925 while the other side has the combined “HN” maker’s mark for Heng Ngai. On the back of each turquoise facet is hallmarked “925 HN China”. Both gemstones are present and secure. The spring backings work perfectly and are not loose. The only flaw is some generalized oxidized tarnishing throughout which can be polished. Total length measures 1.75”. The turquoise stones measure 0.5” long and 3/8” across.
