Artisan Sterling Silver Sea Blue Quartz Necklace Citrine? Jerome Arizona

Artisan Sterling Silver Sea Blue Quartz Necklace Citrine? See original receipt. Purchased at artist co-op in Jerome, Arizona 2006. Not sure what the large stone is (perhaps orange citrine?). Blue-green beads are sea blue quartz. Small beads in between are faceted and iridescent crystals. Length is adjustable from 14" to 15.5". The bale, clasp, and setting for the large stone are marked 925 Sterling Silver. Excellent, clean condition. From smoke-free home.
