Beautiful 18k gold and very clean sparkly diamonds. I do not know the weight of the diamonds. It’s been sitting in my jewelry box and I have not used it. The pink tourmaline is over 23 carats. Note the pink tourmaline has a small chip and is included. Your jeweler would have to put a larger bale on this pendant if you want to put a necklace through it. 💫note it was very hard to take pictures of this gorgeous pendant because the diamonds sparkle so much.
