This is one of the most well made and pristine Star Sapphire rings I have ever had. It has recently been sized to a 7. It has a 8.75 mm by 6 x 6.5 mm violet translucent natural Star Sapphire of @ 2 CT. It weighs 7.5 grams in size 7 and has two accent Diamonds which are well matched at 'G' SI2 and @0.18 CT TW.
I think that this would be an ideal ring. It cannot be made larger but could be sized down. I took a lot of pictures, but I am sure you will be very pleasantly surprised with how much finer the ring is in person.
