VINTAGE ABSTRACT gen yellow/orange SAPPHIRE COBRA filigree 925ss ring! RARE!

Took me 2 hours to clean all of the stuff out of the scales! But look how amazing this turned out! Looks almost new! Estate find Size 6 A whopping 8.14 grams! Of solid sterling silver! Cobra scale filigree all around except on the inside, where your finger touches creating a comfortable fit Extremely high end/high quality! A genuine yellow-orange colored (almost bi colored) sapphire, pear cut, and MAGNIFICENTLY AND STRATEGICALLY cut in such a way that it appears to have EYES like a cobra! only further adding to the uniqueness of this piece! Stone measures approximately 15x10mm or 5.75CT I cannot be certain if this is a lab or genuine stone, it is so clear and gorgeous! I’ve looked high and low for one like it and can’t find one AT ALL! Marked PK (inside a circle) & 925 (Makers mark indicates it is a jeweler Peter Krause from 1879-1922) making this antique, if that is the case. I cannot find another makers mark that is the same as this or close to it. I am unsure of the designer 100%. So don’t quote me on this. Stone and ring appear to be in magnificent condition. Nobody will have one like it! Perfect for those who love a good conversation starter or something to break them apart from the rest! I ship daily in a ring box Offers welcomed! I have just recently been diagnosed with a rare, progressive brain disease called Erythromelalgia. I am unsure how long I will be able to work, so I have begun trying to establish a secondary income. Thank you for your support
