Vintage Exotic POOL of light Japanese necklace

Genuine Japanese revered rock crystal was seen as the crystallized breath of the White Dragon (dragons represent powers of creation). The purity of the gem impressed them as unattainable, but desirable perfection.. This late 1800’s genuine pool of light is set in the most exotic leaf bale with beautiful detailing that wraps around this antique stone. I believe the just the wide fancy bale is sterling . The wide antique rollo chain has a scroll work barrel clasp on it. The length is 15 ½” with an additional 1 1/2” for the pendant. The way to tell a real pool of light is to hold it over print and when you look thru it, the print will be upside down. I tried to capture that but it was hard to get the right angle since there was such a large bale. This is OLD and absolutely full of good Karma!. From what I understand this came from Japan and was passed onto family members who eventually sold it off in their estate. What a wonderful old piece!!!!
