Georgian Garnet, Turquoise & Pearl Quatrefoil Brooch Roman mounted in foil backed "pie

mounted in foil backed "pie crust" settings - the foil and the silver both used to increase brilliance/brightness and accentuate their colour

and the design is impeccable: simple yet striking

it's very possible it was referencing the same (seemingly very generous) John McKean Esqr

It's crafted in 9 karat gold with clasp hidden behind one of the hessonites

the unusually specific design
