From my personal collection, this is an Antique Clear Rock Quartz Ring with 2 Barrel Deep Green Color Tourmaline gemstones. Made from one piece of quartz and tourmaline, it is hand polished around the band, and left in it's natural state on the top - and full of unknown history. I purchased this about 25 years ago when I lived in San Diego and frequented many unique Antique stores in the area. All I can remember is this was some sort of "shield" or symbol of spiritual protection
Clear Rock Quartz is known as the Master Healer, and is a powerful amplifier of energy, clarity and intention. Green Tourmaline is highly regarded for it's ability to heal emotional wounds and foster a deep sense of inner peace. The combination of the both the workmanship and this natural specimen makes this a truly special ring!
The ring is a size 8 and measure 3/8 inch wide at the back of the band and 3/4 inch on the top - it rises (at it's highest level) to 1 inch
