LOST: engagement ring with two snakes

I'm heartbroken to write that yesterday evening  (Thursday, 16th November 2022) on Stroud Green Road near the Old Dairy I may have somehow lost my engagement ring, which is 15ct gold with two smiling snake heads inset with moonstones, really distinctive, with a hallmark inside.  It was dark and raining, and I walked and cycled on Albert Road, Stroud Green Road, Regina Road, and down Upper Tollington to Hornsey Road.

The ring looks quite like https://www.vintagejewellerycompany.co.uk/products/9k-gold-entwinde... but with blue moonstones.

I'm cursing myself for not knowing where it is, and I'm really praying that I somehow misplaced it at home, but if anyone finds a ring, please contact me!
