Blue is scarce - but rarest of all is the white set. A familiar pattern known in marigold and amethyst punch sets. Probably less than 20 known altogether. Red punch cups are known and we understand a red punch bowl and base are reported. Marigold and helios are the most available colors.
Purple ones are spectacular and rare.
Amber, blue and smoke are all exceptionally rare - but are reported. A most difficult set to find. The punch cups are very difficult to find - and are exquisite. They have a single leaf in the center, with no grapes. The inside of the cups matches the bowl interior.
