Thank you for viewing. These are stud earrings set with approximately 3mm natural rubies, using K18WG (white gold) for the base metal. Both posts are stamped with "017 K18WG" indicating the stone and metal type. These are unused, as they have not been tried on. They come with double-lock fit catches, which combine K18WG metal fittings and silicone catches. These also have a K18WG stamp. The catches are also new and unused. Double-lock fit catches alone are sold for a considerable price. There are no other included accessories. Colors may appear different from the actual product due to the monitor and shooting environment. Please understand. Please contact us if you have any questions. As this item has been handled by a person, please refrain from purchasing if you are seeking perfection or are overly sensitive. To prevent product substitution, returns are not accepted after shipping. Color: Red, Pink Shape: Catch/Stud earrings Accessories: None #Ruby #K18 #K18WG #Earrings #StudEarrings
