I bought this product on 2025
The gold color is changing to silver
Not happy for this
Paid over$100 to get a quality but very disappointed
I think the seller should send me a new one free

It is not wearable

The WORLD is your oyster, buy it sis.
Color: Ocean Blue, Color: Ocean Blue
I bought this as a back up and I am blown away! The packaging/gift bag is so cute! The color? Eats zown. Hard for me to describe the color but it's mesmerizing. Worth the money. The quality is very much VC-ish.
