I've had these vases knocking around the house (as glass does...lol) for ages. There's some good quality cutting on them and I particularly like the wide and deep flat cut about halfway down. Actually, some cutting on some tumblers that Bernard had at Cambridge reminded me of this pair of vases. Previously, I'd never thought anyone could identify them...but maybe Bernard can? Or someone else?
Measuring: 25.5cm tall, don't think they're crystal, but I could be wrong, flat polished base with no markings.
