Vintage 950 silver lapis lazuli brooch pin

This brooch pin is from an estate purchase, in good condition with exception to the lapis stone having a light crack in the middle that doesn’t seem to affect it’s stability but adds a rustic look to it.  Genuine lapis lazuli oval cut cabochon set in 950 silver. This has been acid tested for purity verification. Since the silver content is higher than sterling silver, it won’t tarnish as much as 925 silver. Possibly from the Middle East or UK. Total weight is 7.35 grams. Reasonable offers considered
