Beautiful but hard to lock/closed
Color: Pearl White
It’s really nice. The only reason I put only 4 stars is because it’s hard to close/lock it by yourself. Takes a few seconds, but everntually you’ll get it. Love that it’s mother of pearl and 18k gold plated, you won’t worry that it will smell like a rust. Material and quality is good. I have a big wrist and the size is just perfect for me. This is less than 8 because 8 is too big for me and 7 is super right only, not much allowance.

Prettiest shade of blue MOP & beautiful bracelet!!!
Color: Ocean Blue
I instantly fell in love with this bracelet simply because of the blue Mother Of Pearl!! I love that it's 14 kt gold over stainless steel, because it won't turn or rub off so easily. It's absolutely gorgeous on the wrist & I can't stop wearing it! 10/10!!!

Great for use atop the bedside table!
Very nice! I bought this for my father for his birthday, and he really liked the gift! It's a nice little place for him to keep all of his essentials together on the bedside table. No more losing his watch, keys, wallet, etc. or knocking them off the table!
