Beautiful ring, however colors start to fade after a while
Gem Type: Created Turquoise, Ring Size: 9
I love this ring so much. It is so beautiful in terms of design and colors and fit on fingers. I love it so much that I wear it all the time, and I get so many compliments as well.
The only problem is that the gold color and the stone colors start to fade after a while.
So I guess it's not the kind of ring that you can shower, play sports and do laundry with. Probably best to keep it for occasional use.
I would still highly recommend it and would probably purchase another one when this one goes stale

Amazing beauty and quality
Gem Type: Created Turquoise, Ring Size: 5
This ring is stunning and one of a kind! The first one I received had a defect, but I received a replacement in one day! The gold is authentic and polished- even after having my hands in water often. The turquoise is an amazing complement to the 18k gold. This ring is "go anywhere, anytime" and I'm looking for more Ross Simons jewelry, besides all the pieces I already have. Please give this ring a try- you will love it.

Pretty
Gem Type: Created Turquoise, Ring Size: 8
Pretty ring. Definitely size up due to width. Less substantial of a ring. More dainty than I had hoped but still very pretty.

Ring is gorgeous! It does look smaller in person than how it is pictured but still a nice ring.

The color gold is fading to cheap silver and the color is not very nice
Gem Type: Created Turquoise, Ring Size: 8
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
I can return the old one
It is not wearable
