oh man! so close. I have something that may have worked, but not sure on the finger size- my current setting is not platinum but 18K palladium white gold- very strong with a great color. It's a twisted halo so not sure if it's your taste, but it is super low and a band fits flush on either side of it ( i wear it with super think pink diamond bands on either side). Custom made (a mix of CAD and hand forged) for 2.5K, i am planning on listing it for 1500.
It is a size 4.5 though...there is a space in the back with no diamonds to make bigger but not sure how it would impact the overall design.
Hi! I had it made in Southern California from Liberty Diamonds- they do amazzzzzzzing work, expensive but worth every penny.
Its not an eternity band- I kept the back without diamonds specifically so it could be potentially sized up/down later on. Center diamonds is 6.25MM, but i know it can fit smaller because I took my diamond out and tried it out with a 6MM sapphire ( I am selling my center stone but was going to keep my setting and see if I could make it a mothers ring) and it looked almost exactly the same.
You can message me through one of my many diamondbistro listings if you want to chat more.
Thank you so much! i actually love my ring, but i always wanted a big cushion diamond sooooo have to sell in order to upgrade if it goes to a good home it makes it a little bit better
