Can someone help me identify and date this please. Enamelled applied pattern design with engraved crossed etching around the top half. The crossed etching lines on close up inspection are not parallel and some of the lines do continue under the 'circled' enamel patterns lines, with some running straight through. The goblet/candle holder has a high pitched ring tone even when held firmly by the base. Would this indicate as having crystal content? The paintwork and engraved markings are all hand applied, as no specific pattern is identical. The gold guilt paintwork which also is around the rim opening, the single rib neck and upper base rim, does show signs of ware. The base, measuring 7.6 dia. Approximately 1.4cm from the base edge leading towards the centre is slightly concaved. If blown glass I would assume this will be the pontil? If it is the pontil area, it is mottled/textured. Ive not seen this colour before and not having much luck with my research. The Goblet/Candle Holder is approx. 11.4cm in height.
