These earrings feature small, lustrous freshwater pearls and a concave cut that resembles loose gemstones. The chain is also made of 10K gold. A pendant top in the same design, made of 18K gold, is also available. https://minne.com/items/42916459 Materials: Hook: K10 yellow gold, Wire: K14gf Size: Length: Approximately 44.5mm, Width: Approximately 10.6mm The K10 (10K gold) used contains at least 41.66% gold (Au). 10K gold is used for chains, jump rings, as well as earring and pendant findings, and bracelet clasps. The "K10" hallmark is stamped on the findings other than the chain and jump rings. After use, wipe with a glasses cleaner and store in a zip-lock bag or something that can block air to keep it in beautiful condition for a long time. Notes: Please refrain from using abrasive cleaning cloths. While there is no problem using it on 10K gold findings, the wire uses K14gf (gold plating), so there is a risk of the plating coming off. Also, please be careful as many natural stones, such as turquoise and coral, are sensitive to abrasives. Motif Material...Natural Stone, Pearl
