Lemon Quartz Necklace Sterling Silver Vintage Delicate DazzleCity

I'm calling it lemon because I don't think it's jade or opaline. I've had them since the late 80's so I can't remember anymore. Not a rock expert just saying. From my vintage stash - the quartz measures 1 and 1/4" long point to bail. Nice sterling silver top.  The chain is an 18" silver plate with a spring ring clasp. Nice little statement.
