**See the Reasonable offer Chart before you make an offer! I don’t play the counter offer game especially with my vintage jewelry! All indecent offers will be ignored!** **I use lots of essential oils in my house! U have a problem with fragrances, do not buy from me!** Here is a vintage from the 1980s/90s Black Onyx tumble stone key ring. I think this one is Black Onyx because onyx is typically a flat black color and is slightly lighter than Black Obsidian. It has never been used and is in very good condition for it's age. The stone is a large 1" by 7/8". It is unmarked. See pic.
