Victorian blue glass diamond cut fairy lamp with Clarke base

The fairy lamp section of my collection progresses slowly, mostly by putting together orphan parts.
I was lucky to find this small blue diamond cut dome to match up with a spare Clarke lamp cup I've had for many years (it was found alone in an op shop, among some glass salt cellars).
The dome was found on eBay AU, at a pleasingly low price.
A little something to make our current lockdown less of a misery. Here I am, fully vaccinated & can't go on any shopping excursions except to the supermarket...
