Wow! I can’t recommend steinhardt more. They communicate great and they deliver exactly what was expected!
It is made of great craftsmanship and so shiny you can see it reflect in the dark! The claws hold the diamond exquisitely and I have no fear of the diamond getting loose. Its made to absolute perfection and I am so glad I chose this style for my ring!
