Hi Ruth
Few people would know the difference. Those who had Nason / Murano in their collection might look suspiciously and some experienced general collectors may smell something amis but many would people would think Murano so don't beat yourself up.
I have seen a number of interesting and rather attractive pieces with adventurine, usually on turquoise and I am now wondering if they are from the same source. I have found a few of pics I kept for reference :
Adventurine on Turquoise swirl Bottle Vase Adventurine on blue Bulbouse Vase 8.5" Adventurine on bright PINK cased clear vase The first time I saw one I was very tempted. If it had been in UK I think I would have bid on it. Since then I have seen many many more and started to get suspicious as they were appearing all over the world, at very varied prices and too frequently for comfort. The pink one I had no difficulty in resisting ....This color alone makes me wary.
These do not look particularly thin though .....hmmm
Also I am guessing that our esteemed guest took the inverted base "nipple", which Tiger rightly highlighted, as a key indicator of his attribution. I do not have base pics for these.
Dalian light Industries is not a name even known to 99.99% of glass collectors. It takes a researcher of some dedication to to know of such makers let alone confidently attribute to them . Thank you guest.
PS Ruth Adventurine is not copper ...it just looks like it sometimes. To find out more about adventurine use search above as it has been covered before.
