Tiny Tuesday...Mineral

A massive thank you for all the generous comments, stars and hearts yesterday, for my 2190 blip anniversary, overwhelming, but all very much appreciated
Back down to earth today with a photo of one of my late mother's rings, a beautiful square ruby, surrounded by diamonds. No idea when it was gifted to her, possible on her ruby wedding anniversary...hope it fits for the challenge today of mineral.....thanks to Freespiral for hosting:)
Did anyone watch 'The Great British Photography Challenge' last night on BBC4? Six hopefuls, mentored by Rankin for the title. It was most enjoyable, lots of tips and feedback, four episodes I believe, and on iPlayer if you want to catchup.
