I purchased these rings as replacements after my wife developed an allergic reaction to her original gold band. Tungsten Carbide doesn't cause a reaction. This ring is comfortable, looks great, extremely scratch resistant (had them for a few weeks now), and has a near identical weight & color to my original 18K band. Her ring is obviously not dainty and delicate, but that's a preference you already know just by seeing the product photo on Amazon. Speaking of the product photo, on the real ring the gold part is slightly thinner and the silver beveled edges are slightly wider. Hardly enough to notice, not enough to ding them on it... 5 stars!

NOTE: the photo in this review is my ring two years after purchase. Worn daily, through tons of manual labor, ocean, washing, cleaning, etc. I NEVER take it off. Notice the lack of scratches. It's super durable! However, my wife's ring has had all the gold come off. Weird.
