Looks gen. They're solid 18k and the facets tend smooth out over time. This one's been worn down pretty good. Also, the gens have a little circle on the underside that should have a tiny crown. The circle is there, though the tiny crown is not visible from these pics. You should ask for the weight. The 16200 version is higher for the sapphire crystal and heavier (more gold) than the older 16000 versions for the acrylic crystal models. If a 16200 version, should weigh at least 4 grams. If it's the older style, should be around 3 grams. the 16200 versions should cost more because more gold. The price seems insane. There are a ton of these out there and should be much lower, especially given the amount of wear.
