She brought in her ring of yellow sapphire. 
Her dad was a stone cutter and the sapphire was cut by him.  Also the ring was designed and made by her when she was very young.
Rectangle shaped pretty yellow stone....!   We thought about our unique and beautiful design "Candy Wrapper", and showed the 3D model which we happened to have to her.
She loved it and now she is enjoying her dad's stone in the new design.
