14K Gold Diamond Nugget Pendant

Solid 14K gold nugget pendant is signed MC and features two Diamonds for a total carat weight of about .10ct.  I do not see a 14K mark but it has been tested by a jeweler.  It measures about 7/8 inch, including the bail, by about 3/8 inch wide.  It weighs 2.5 grams and it is in great vintage condition.
