First produced in France, in around 1845, fine glass paperweights are to this day widely produced, collected, and appreciated as works of art. The most sought after pieces are produced by sole artisans usually in limited editions. When determining a value of any given piece there are a number of factors to consider. These include: workmanship, design, rarity, and of course condition. While many can be picked up for as little as a few dollars, some of the more desirable ones can fetch extremely high prices; the record to date is $258,500 once paid for an antique French weight.
