Turquoise gemstone ring

How can I sell this Turquoise stone its so lovely. It has tiny facets cut into the face of the stone so that the light bounces off it and makes it shine. I have set it with a decorative wavy edging and set upon a wide 1 cm band

Turquoise is the birthstone of December.

Hallmarked by the London Assay office and y own JRJ hallmark.
