Am told that this is crystal, but do not actually know myself, so is sold as is, but it does have a nice clear ring, and it is reasonably solid and heavy (just a bit under 1.4 kg) Measures approx, at its widest points, 265mm x 260mm x 30mm high. (has a raised edge on the sides) Could possibly be semi hand made perhaps because to me it looks a bit uneven, unless of course they were made just to look like that. Anyway, nice display piece or useful as a serving tray for nibbles or such. Thanks refN14814183A
