Not very comfortable
Color: Black, Size: 42D
Just okay. Provides support but doesn’t particularly minimize and isn’t very comfortable.

Gorgeous!
Color: 01.Heart Cut, Style: 04. April (Diamond)
I love this necklace! I wanted something that represented my birthstone, but did not cost a fortune and could be easily replaced if it’s ever lost. I have very sensitive skin. Seriously, I’m even allergic to gold unless it’s pure. This necklace is perfect. The chain hasn’t bothered the skin on my neck since I put it on. The size is perfect for me. It sits exactly where I want it to. The pendant is a true Goldilocks - not too big, not too small, but just right! I love the way it looks in the sun! Sparkles, sparkles, sparkles! This is definitely going to be my go to, everyday piece. I highly recommend this to anyone who is even a little bit interested in buying it. You won’t be disappointed. It makes a wonderful gift for ladies and girls of all ages, or simply as a treat to yourself! Choose your birthstone or your favorite color! In fact, I’m considering which color to purchase next. Can’t say enough how much I am in love with this amazing piece!

Sparkling ✨️ Pretty
Color: 02.Round Cut, Style: 04. April (Diamond)
The chain is very nice, can adjust it to 16 to 18inches. Appears to be 925 sterling sliver. The diamond charm is about a diime in size. It's sparkling and pretty. I can't decide if the charm is to big or not for me. All in all 40. Spent on it was ok but no more.
