These beautiful toppers are cast to order from a gorgeous selection of antique toppers we have sourced from around the globe. They are available in gold, silver and rose gold toned base metals. They tarnish beautifully over time, and are easily polished back to new if desired. Our current style includes the option to insert a semi precious gem or crystal - you may like your birth stone, or a stone to replicate that -(I dread to think what a diamond of that size would cost!) or a crystal representing calmness or strength or to help ease anxiety in the ring.
