I wear this ring while working so to not damage my much softer 18k yellow gold wedding band.Pros: Ring is true to size, as I have several 12mm rings in the same size. Surface polish is excellent considering the amount of machining that had to be done on this piece. Sparkles and shines like crazy. From a distance the individual pyramids give the illusion that they are diamonds.Cons: The ring is specified as having a comfort fit design, although this is not evident. This consequently makes the ring feel tighter although it is the same size. For example, this ring requires soap and water to take off compared to my other comfort fit rings which do not require this as they are more aggressively cut on the inside. On both sides of the ring there appears to be a seam between the inner and outer parts of the ring. This is detectable visually and with a fingernail. It almost looks like they were milled separately and then fused together somehow. To me it is kind of a sloppy finishing job, whatever they did. Although this can't be seen when wearing and have to look closely. You can see this slightly in the stock photo and in the second photo I posted where it is zoomed in. Is there anything structurally wrong with this? Appears not since everything is solid. Would buy again.
