David Yurman Opal Cable Kids Bracelet purchased approx 2001. Perfect condition. Pretty sure it's opal. It's a pearly stone with irridescent greenish tint. Good size for petite adult woman with small wrist (that's how I used it and my wrist is 13.75cm or 5.4") but could work for a child/teen as well. I have some other DY jewelry so feel free to make a bundle. Similar to this current style diff stone. https://www.davidyurman.com/gifts/for-children/cable-kids-bracelet-in-sterling-silver-with-14k-yellow-gold-and-pearls-4mm-KB1046+S4BPE.html?dwvar_KB1046%20S4BPE_color=PE&dwvar_KB1046%20S4BPE_metal=S4&dwvar_KB1046%20S4BPE_size=S&quantity=1 Here is a past listing from Poshmark that sold https://www.therealreal.com/products/details/jewelry/bracelets/cuff/david-yurman-two-tone-opal-cable-kids-october-birthstone-bracelet-86jex
