Art Deco 'Flippy' Ring in Bright Sapphires, Rubies and 'Old cut' Diamonds in Engraved Platinum

Ever popular , Art Deco 'Flippy' ring as I like to call them or 'Flip over' ring as they are better known. Ever so often one pops up in the condition I like; good, bright coloured, with good condition stones (slight wear only, never too rubbed), 'Old cut' diamonds, finely engraved sides (not too much wear to engraving) and of course, it has to be Ca1920/30's.
And then of course there's the other variable, it has to fit. And I don't have. much choice in that. If the ring is in a super condition, and meets all my requirements, whatever the size, I buy. This ring is for the larger hand and is a size 'P' (UK), 8 (U.S). It cannot be sized. 
The rubies are bright, a lovely pink/red colour, with fine wear only. The sapphires are bright and a 'Royal blue' colour, with fine wear only. The stones are all well matched and are all 'Channel set'. The diamonds are all bright, lively and sparkly and measure approximately 0.02/0.03 cts in size . The engraving is still very visible. The individual diamond half hoops are connected via hinges to the central ring which is made up half of sapphires and half of rubies. It can be worn either with sapphire centre or ruby centre. All that's required is a 'flip'! 
The ring is in lovely condition, with fine wear, commensurate with its age.
