This intricate ring from Dua Adorned conjures up Medieval poison rings … but you would probably want to keep something a little less lethal in this.
The site explains, “An intricately detailed locket ring designed with a double twisted wire ring band that splits into two holding up a hinged box. The locket box has a four petal Batik inspired flower. The edges of the box also feature a carving that mimics the twisted wire band. Designed to be a unique piece of jewelry to hold things that are special to you. We like to keep dried lavender petals inside the box because… well, lavender is amazing.”
This sells for RP 1.320.000 (Indonesian Rupiah).
