Excellent
Gem Type: No Gemstone, Ring Size: 9
I don't usually leave reviews but this ring is gorgeous. It's weight is good. Design is beautiful. Some gold u buy can be really thin n flimsy but this ring is substantial enough. Im truly enjoying it. Will buy from them again.

Replaced wedding band after 43 years
Gem Type: No Gemstone, Ring Size: 10
I am thrilled with this ring. After 43 years, due to arthritis and aging my knuckles were too swollen for my original band. This is a very pretty, sturdy, detailed ring. I have received many compliments and I am well pleased with the quality. It was also on time, well packaged and a notice was sent of it's arrival. Very nice. Highly recommend.

Not a ring you want to do hard dirty work in. Worth taking care of
Gem Type: No Gemstone, Ring Size: 8
I had mixed feelings when I got it. It is very lite weight. Next to my other gold jewelry it looked like a different color. It is 18k tho and my others are 14k.$300. To me ain't cheap. I have wanted this ring for along time. I started to send it back. Hubby talked me into keeping it. I got a size 8 so I could wear it on my thumb or middle finger. I have arthritis in my hands so rings fitting is a challenge. Some days I can wear them, others I can't. This ring is beautiful and being lite weight is a plus when your fingers hurt. So glad I kept it.

Order one size up
Gem Type: No Gemstone, Ring Size: 8
This is a beautiful ring. I would suggest ordering one six up from your normal ring size because it is a wide band. I had bought the bracelet a year ago and wore it everyday never took it off and the links slowly started breaking and separating to the point I just traded it in for the Wright of the gold. I hope it does not happen with this ring. I think it’s made with hollow gold and it is soft. It is a very light but comfortable band. I don’t always like to wear my diamond ring because I don’t want to loose any stones. This is good for casual everyday wear.
