I was interested in both the santos de cartier necklace and bracelet in YG but found out they are semi-hollow. Both felt light on my hand compared to my solid gold pieces. The cartier love bracelet on the other hand is solid gold if you prefer something substantial.
I also looked at the tiffany hardwear link bracelet and necklace but unfortunately theyre also semi-hollow. You have to do research nowadays to see if you’re purchasing solid gold jewelry a lot of designer jewelry are using semi-hollow pieces.
