Black Onyx and Sterling Silver Earring,Bracelet, and Necklace Set

Unsure if this is black onyx or obsidian. All I know is that it is very well made, sterling silver, stamped, along with the makers mark and also the countries. I know Thailand and Italy, which as anyone knows the Italian silver is the best. The bracelet is a cuff that closes with the hook shown. The stone is almost 1.25 inches long and an inch wide. The necklace is slightly bigger. The chain for the necklace is oxidized silver. You can see the difference between highly polished and oxidized very clearly. You can also see the makers mark. This is from the 1980s. It's not been worn as it should have been. The bracelet us a standard size width, 2.5 inches across at the widest point so that converts to a 7 to 7.25 inch bracelet. If you want the healing properties, the stones do touch the skin. The chain is total with pendant 20 inches long. The earrings are faceted, and secure in the setting, as with the other stones. Will break up the set if you ask. Feel free to submit an offer. TYIA. :)
