Beautiful natural blue sapphire and diamond necklace 10k yellow gold Italy stamp on clasp 17" length 5 grams t.w. Unknown carat weight of stones. I purchased this from Zales in 2002 and don't have the exact carats and weight of each stone. Excellent condition. Only worn once, and it has been stored in the felt envelope from Zales ever since. Please look at the pictures provided and ask any questions prior to purchasing.
