This is a set of antique crystal stemware. Each glass was hand blown, hand cut, deeply engraved with Rococo Revival style decoration that was then gold encrusted. These glasses can be attributed to the French firm known as St. Louis and would date to about 1890 - 1900. Although the gold is real, there is no longer a precious metal meltdown value as the cost to extract the gold would exceed the value of the amount extracted.
The estimate is for the set of 8 glasses altogether and is based on actual recent past recorded auction sales of comparables.
