Hi Cathy,
Aventurine does turn up in repro items, but I find it has a lighter, more golden tone than older aventurine, which tends to be a deep,intense, copper colour.
I have a collection of aventurine jewellery, which spans the period from Victorian thru to present day. Seeing the change in colour over the years of production is quite intriguing.
I also think that older aventurine tends to have a more concentrated & brilliant sparkle.
Murano had a monopoly on aventurine up to the 19th C. Since then it has been made, in varying quality, in various glassmaking countries.
Aventurine was/is also exported from Murano in cane form to be used in glassmaking elsewhere.
Sybille Jargsdorf's excellent book, "Glass in Jewellry" has a whole chapter on aventurine & it's use in both jewellery & glassware.
I have a few repro items (bought very cheaply,long ago) of aventurine spatter on black & red cased glass (in the style of Nason-there's a thread on this firm somewhere in the Murano forum).
One of these was marked "Made in China", & was purchased new in a bargain shop in 1999.
I am uncertain as to whether the Chinese manufacturers make their own aventurine, or buy it in from elsewhere.
But all that glitters is not aventurine! There are loads of Murano items that have gold foil/leaf inclusions that
aren't aventurine. True aventurine is made from copper & should have a deep copper or red-brown tone.
I have a 50s Murano bowl that has the full range of metallic inclusions-silver foil,gold leaf, & aventurine.
As for this vase, it seems to be a recent Murano item. I have a small vase,
sans handles, with the same canes & an all-over dusting of gold-leaf.
It is card-carrying late 1990s Murano.
Hope this has been helpful!
