Large vintage or antique rock crystal (quartz) 'pools of light' style drilled bead chain strung bracelet & matching drop earrings (pierced)

Gorgeous rock crystal large round drilled beads strung on slim silver tone chain to make a beaded bracelet and matching drop earrings for pierced ears. I have struggled to date these beads - I assumed they were vintage or even antique, but natural stone carved jewellery is still being hand-carved across the world. The design certainly has a vintage/antique feel to it. The bracelet has an adjustable length between about 7 and 8.5 inches, using the spring ring clasp and extension chain. The earrings each have a length of about 2 1/4 inches from top to end. The pieces are all in very good vintage condition.
