These strands came out of Brazil 100% natural. Funny to call rocks vintage isn't it? I purchased an entire load of different type strands back in the late 80's. This is not some fake dyed howlite rock - these are true rose quartz beads - chip form - they range 3mm to 6mm in size and make for lovely accents. The strand measures 35" long. It's strung on pink silk thread so the hole is not big.
