Murano Mandruzzato multi faceted vintage vase. Cut faces, square diamond. 50s/60s/70s Mid century MCM. Red sommerso glass, retro Italian

A perfect example of a Murano sommerso multi faceted glass vase, attributed to and probably by Mandruzzato, Murano, Italy.
It's 20cm tall. It's a pure red colour with a slight floating submerged colour (sommerso), all cased in clear.
It's 1.3kg and pretty thick solid glass - a super chunk of vintage art glass.
Square (flat and polished) top and bottom with 12 cut off sides, diamond like, flaring out then in towards the base.
12 sides (4 x 3 if you study the photos).

Can't find any chips, nibbles, fleebites. As far as I can see this is perfect.
Vintage 50s/60s/70s Mid-century iconic design - unsure of exact vintage of this example.

No water staining or marks. Photos don't do this justice.
If you're after one of these vases for your collection, you can't get better than this example!
Perfect for a Mid-century mantelpiece - ideal gift for a collector.

I can post abroad but due to the weight it's a bit costly.
