This stone was made 25 years ago and is brand new out of the box. The stone is one of the finest we have ever had in our family's 30 year history in the jewelery biz. A 4 ct ( 11 x 8 mm ) extremely well cut Emerald shape center stone. We sold right out of these rings when we had them on Ebay earlier. We just finished these rings and we are offering them at a fraction of their original price. If you want to know if our stones last, our family has been wearing our stones for 30 years and we still fool everyone that sees them. The stone is from our top 25 year old vintage inventory and the ring mounting is newly made. Designed to last a lifetime this solitaire ring made of sterling silver .925 with a rhodium finish so the silver will not tarnish and looks like white gold. This is the type of stone we used in the video to fool jewelers.
