Just an FYI. They just posted a catalogue for the next sale.

If you look under the bid price you'll see a price spread eg."120-200", this is the estimated sale value. Might give you a rough idea if your crystal is similar. Keep in mind you have to pay them a commission, no idea what that is these days, probably 30%ish?
