Crochet chain links necklace. By Laura DeZimm and for sale on Etsy.
SALE - Beautiful Glimmer Gray Dusty Pink Fashion Crochet Necklace Lariat Bib with Shell Ring Beads. $24.00, via Etsy.
No foundation chain. I've seen this on Pinterest but not a good tutorial before this one. Once you understand the pattern it goes so much faster than a foundation chain and double crochet with much looser tension.
