This is one of the most well made and pristine Star Sapphire rings I have ever had. It is a diminutive ring as it is size 4. But it packs quite a punch. It has a 8.75 mm by 6 x 6.5 mm violet translucent natural Star Sapphire of @ 2 CT. It weighs 6.5 grams in size 4 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 pinkie ring. But it could also be sized up 2 sizes, no more, without ruining the scale of the ring. 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.
