I’m coming up on a milestone anniversary and would love to have a special piece of jewelry to celebrate the occasion. I currently wear a 4 carat tennis bracelet everyday. I’m thinking of either getting an upgraded tennis bracelet (8 carat) or a dainty tennis necklace (5 carat). I don’t want either one to be too fancy, as I work in a pretty casual environment. Would love thoughts on which piece is more versatile. I see a lot of tennis bracelets worn daily but not tennis necklaces. Does anyone own both pieces and can offer their opinion? Thanks!
