Sorry all. I was visualising Christine and thinking your name Sue, doh!!
Something I didn't detail earlier was that there were five items of Alexandrite in each of the Parkington sales, making a total of ten, but split into six lots (three in each sale). The largest (tallest) piece was a single drinking glass with a hollow stem, having a ribbed foot, but bowl and stem were plain it - this was the one that achieved the highest price. The ten pieces split into five plain and five with diamond moulding.
Noting the split of moulded and plain items it is therefore not a characteristic that should be used for identification of Webb's Alexandrite.
Blimely Sue, she doesn't let me hug her, so................
Cheers, Nigel
