I currently have a set of OVAL Blue Topaz studs set in 22 Karat gold. The silver hollow form enhancer will need to be made. The enhancer is hinged for movement and can be removed so that the studs can also be worn alone. The price listed here includes the enhancers. If you would like to purchase just the studs, please contact me for the price and to place to order, as it will reduce the price.
