diamond & ruby ring

[Terence]

Hello, I hope I'm not posting my question on the wrong platform or the incorrect forum, if so, kindly nudge me away. If possible, please can someone help me. I have inherited a gold ring which I believe to be made circa 1900 (late Victorian) with "L.E.B&B" stamped in it, which I assume is the maker. I have searched high and low through England, Scotland & Ireland in some databases like Jackson’s Hallmarks for maker "L.E.B&B" with no success, maybe a lessor maker 100 years ago that didn't rise to prominence and therefore does not get listed in 'maker' databases. Hopefully someone out there knows! :-) PS : the box it came in had maker "The Goldsmiths & Silversmiths Company Ltd 112 Regent St London W" but I assume that the two don't marry up properly as L.E.B&B is the wrong letters and should be "G&SCo Ltd" or maybe "WC JL" for William Gibson and John Langman who are associated with the company. Please see attachments. Thank you in advance, Terence.
