My client bought an 18 x 14 faceted peridot in Pakistan and wanted a pendant setting for a young lady. On a stone of that size, the pavilion is significant and requires a domed setting to keep the culet within the mount.
The mount is press formed to get the domed oval shape. It was then textured and there are six claws to retain the stone securely. The mount is about 30mm top to bottom. Weight of the sterling silver in the setting is below the UK regulatory limit for compulsory hallmarking and so, as it was needed quickly, it is not hallmarked.
