RARE Pin Sapphire Citrine Olivine Navette Rhinestone Brooch Vintage USA BeadRage

All the glass stones are prong set. Being glass of course it is heavy. It weighs 45 grams. It measures 2 and 3/4 inches across and 2 3/4 inches tall - it's a big one. The stones are all secure and vibrant - no dead stones, cracks, chips or fleabites. There are tiny slim olivine navettes sandwiched between the pear shaped larger citrine / topaz. Really nice light sapphire marquis prong set stones along with jet black rounds. Larger emerald cut center is also black

So here's what I know about this piece. 30 years ago while scouring a basement in Old Providence on my usual quest for treasures - I came upon a stash of these beauties. I sold most over the years but still hung onto a couple - hoarder that I am. They were not new when I bought them so I really have no clue how old they actually are. My best guess is 50's or 60's. This piece is immaculate. The silver plating on the backside is gemmy. It's been tucked away and wrapped for years. Hoarder not wearer
