I bought mine from my Brother -
Troy Vinson Jewelers - Fort Worth 817-377-8555 Granbury 817-573-7881
They do custom work that is amazing. They built mine, my son's and my nephew's. All custom. You can even take your own metal in and they will use it to build your ring. I took in three that were just laying in the drawer and that greatly redcued the cost.
It is owned by a MM (Troy), his sons are MM's; the deisgners are MM's and the sales guy in Ft Worth (George) is also a MM. Two of them are PM's as well. There are York, Scottish, Shrine and other bodies they belong to and understand what you are talking about.
Their pricing is "adjusted" for "family", they can create most anything you want.
Great people, fellow Masons.
