Brilliant Earth antique sapphire and diamond ring

1930’s stunning ring purchased from brilliant earth. I have all the original documents and boxes. I didn’t wear the ring and it is in excellent condition. 18k yellow gold and platinum 3.5mm sapphire I’m the middle and for 2 mm natural sapphire accents. Four 2 mm diamond accents H/I color SI1/SI2 clarity I can’t express how beautiful it is!
