Sterling Silver Cocktail Ring Brutalist Red Stone Wire Wrap English Hallmark Vtg

Stunning cocktail ring in a sort of brutalist style with red material inside a round setting and covered by thin strips of silver. I dont know what the red material is. Marked SLD and also has some English hallmarks that under a loupe look like a crown (Sheffield), lion and a T or a D. I could not ID the maker. Size 6, will be slightly adjustable because the band has a small gap. 6.37 grams.
