Beautiful necklace and charm! Heart shaped synthetic sapphire gem with three small diamonds above it. On the side of the charm, it says "10k" (silver color setting). The (silver color) chain is included and has NC 10k on the clasp. I believe that stands for Nickel Cobalt metals. Chain is approximately 10" long. Hard to notice if any, but it has been previously loved and may have some signs of wear. Not worn daily. See photos for more description. Great gift for birthdays, anniversaries, Valentine's Day, etc Check out my other items, I'm happy to combine shipping!: Visit my store! I try to describe the items to the best of my ability, and for that reason, items are sold 'as is.' I do not usually do refunds unless I have grossly misrepresented an item. Although I do my best to give an accurate description, I may have missed something, so if you have any questions please email prior to the item's end. In the event that I have overlooked a flaw in an item, please contact me before leaving feedback so I can have the chance to fix the problem. I try my hardest to take accurate colored pictures of my merchandise, but please be aware that different computer monitors and phone screens can make colors look darker, brighter, lighter, or just different than they appear when I list the items. I will not give partial credits due to an item being a different shade than pictured as I cannot control this. I accept PayPal and would appreciate payment within three days of item's end. I'll be glad to provide positive feedback and hope you will do the same. Thanks and happy shopping! Be sure to add me to your favorites list! Check out my other items!
