Jewelry, Gems, & Minerals/Stamp on ring


I just purchased a diamond ring with the imprint  MW14K can you please tell me what this stands for?

Hi Tiffany,

It is most likely that MW is a code that the company uses, if not the initial of the makers of the ring (There is a jeweler from Dallas, Texas that uses the 'MW' trademark.) The 14k mark means that the metal of the ring is 14 karat (gold I am assuming.) I hope this helps.
