I ordered the round glasses which are not displayed on the site, but I contacted G&O and they quickly obliged with photos. The glasses are heavy, but decent quality (no seams or undulations in the glass/rim, etc). The mass is in the base, not the thickness of the glass. Engravings are shallow, almost like an acid etch. Between the excellent customer service (from reply to contact to delivery time), price, and the caliber of the product, I am a happy customer. Salut!
