Dates from the 1990''s, i''m not sure how much this was used if at all, has the 14K gold marking, has a single diamond at the bottom of the heart (i''m not sure what it''s karat weight is but it''s really small), the 14K marking is on the bail and there''s another marking as well but I couldn''t make it out (the markings are super tiny and I had to use a loupe to be able to see it clearly), part of the top part of the heart is either silver or white gold (there''s no 925 marking plus with it''s higher quality i''m assuming it''s white gold but i''m not 100% sure), the chain is original with the pendant, and is in good condition.
