My husband & I are stained glass artisans and assure you that this is quality art glass. The nay-sayers evidently do not realize that cabochons (this lamp boasts 81) are round glass gems and that plastics cannot be copper foiled and soldered. Buy with confidence because this lamp is lovely, especially in full sunlight. This is an outstanding deal, by anyone's standards. Tip: Unpack outside or in a garage....the packing is substantial but extremely crumbly and messy.
