The rings are sturdy, and are believable in stone size. Stones are clear and do sparkle. I really like the overall design and presentation. The metal is darker than silver or white gold and I believe they have gotten a little darker in the short amount of time I have had the rings. I have ordered this set twice..the first set had a stone that did not set properly in the channel, which left a small sharp point sticking out.  The second set is great.
