sorry, I'm none the wiser as to origin etc., but yes, your picture is much better.
I think the word is 'aventurine' - which apparently is a form of quartz with mineral inclusions which give that glistening and sparkle effect in the light.
this effect has been simulated, in glass, for a long time, using materials like gold and silver foil, real gold leaf, copper flakes etc. - much use of this made I think in glass from Murano, but am fairly sure never used by Nazeing, although not sure about Monart/Strathearn. Famous last words, but am sure not a Nazeing shape, although appreciate the reasoning behind the suggestion of this factory.
Have to say I forgot to remind you to also include some idea of size/dimension - this won't generally provide provenance, but may well be helpful in some obscure form
Could be wrong, but I'd suggest the stopper in this piece isn't sufficiently effective for a scent/perfume container - so often these stoppers simply aren't a good seal against evaporation etc. - although perhaps could be for cologne/toilet water.
Glass designs/shapes/colour are beyond measure, and without a backstamp/label etc., I suspect you are sadly onto a loser with this one, which appreciate always disappoints, but regret that's the world of glass for you.
Head on block, I'd make a guess and suggest eastern Europe - possibly Czechoslovakian - mid C20, although date might depend to some extent on wear, which is always worth mentioning.
Of course if there is aventurine in this piece, then do shout and put me right pronto
