This pendant is Classic David Yurman and is always in style. This Acorn Pendant has an 18k yellow gold bail and has a classic Sterling Silver rope border with pave diamonds. I am unsure of diamond carat weight. There are no missing diamonds. The back is stamped 925, DY, and 750. This piece is about 5/8 inch long and 1/4 inch wide. This goes great on a classic Yurman Box Chain. If you always wanted this piece, now is your chance as this is a retired style. It will be your every day, wear with everything piece. This is in very good pre-owned condition, it could use a polish.
