What a fun find. These are matte finish, free form Phosphosiderite teardrop beads. We know that the matte finish is all the rage right now, and what a bonus to find them in this fun free form shape. Obviously, no two beads are exactly alike in shape or size. The average size is 12mm. Phosphosiderite is very hard to come by and these are limited, so don't delay. Phosphosiderite is known as the stone of healing and hope. Who can't use a little bit of that in their lives.
