Large Vintage Sterling Silver Heart Locket Necklace

Sterling silver bright cut floral heart locket is marked 925 Thailand and is inscribed "Serena Kim '91" on the inside right.  The locket measures 1 1/2 inches, including the bail, by 1 1/4 inches wide.  It is on a sterling silver 24 inch box chain and the weight of the necklace is 12.4 grams.  The necklace is in great condition, but I will point out that there are no photo holders inside the locket.
