This design is often called 'lovers' or 'entwined lovers'.
There are many makers in lots of colours and sizes. Ferro Lorenzo, Ragazzi, Badioli, Barbaro, Ballerin to name just a few.
I don't recognise the round base in association with any of the above names (usually its a column pedastel in white or black or an 'integrated' foot.)
It's like a more contemporary and chique version of the Murano Clown or baroque dancing couple and nowadays a popular purchase for visitors.
Quality and prices are very diverse. So if you ARE in Murano, look carefully and choose an example that has clear detail and no flaws.
