The rings are beautiful! The Koa wood is rich and dark, the crushed opal is so interesting to look at as it sparkles aqua blue and green. The rings are comfort fit bands so they are also extremely comfortable. The rings fit perfectly, which indicates to me the sizing is consistent with industry standards. I feel like I got a good value for the price. Shipping was fast and just can't find a reason to complain. I would definitely purchase again.
