How do I replace this sort of glass?

[ramsamsam]

I inherited some lovely glasses from my mum but have now gone and smashed two of them. I don't even know what you call this sort of glass. It is 10cm tall and looks like in the picture.

Does anyone know what I should be looking for to get a replacement?

It's cut lead crystal. There may be a makers mark on the bottom.
You can have a look on eBay? Could be a port glass if quite small?

Id say liqueur / sherry/ port glass OP - just looked on ebay and theres loads
type in ‘vintage’ too

Often lots in charity shops around here.

Loads of slight variations but sure you'll find something similar

I looked at the bottom and there is a mark but it's illegible to me. Does it mean anything to anyone else?

It's been hand engraved rather than stamped. I don't recognise the name but it might be a smaller glass studio maker rather than a factory.

It looks like it says Briesley?

A quick Google leads to Royal Brierley?

Expensive though!!! But also a starting point for ebay searches to find a vintage style.

Might be this one. None in stock but gives you a starting point.
