Oxidized Nickel-Free Sterling Silver 4mm Round Byzantine Chain Necklace & Bracelet Set for Men and Women - Adjustable 7-30 Inch with Hook & Eye Clasp - Perfect for Gifts, Weddings, and Everyday Wear

Great quality. 4mm 30 inch byzantine is the perfect size. Some pendants might not fit but the chain itself is nice. 2.5mm is what id say is normal width. I wouldn't go under 26 inches though. Unless youre under 5 feet tall. It's a solid well made necklace. As far as silver goes, this is one of the nicest I've ever had.
