One of the coolest things I picked up yesterday at the gem show was a calibration weight. Perfectly tuned to 100 grams, this weight is used to calibrate your scales and make sure they're in sync.
At home and at work, I use gram scales all the time and the gem show is one of the few places where I can go, buy a gram scale and not have funny or "knowing" looks between me and the person selling me the scale. In America, it seems that the only people using gram scales are gem dealers and drug dealers. In a way, they're all scam artists selling highly addictive products.
Come to think of it, baristas, jewelers and drug dealers all seem to have this in common. Go figure.
And, as any dealer (drugs, gems or otherwise) will tell you: we live and die by the scale, so it has to be accurate and on the money. A couple of grams off and you're talking profit or loss. In the millions. So, a calibration weight is a handy tool.
Some of our scales have been in constant use for nearly two years now. They're dropped on the floor, plopped into drawers, tossed around, slammed around, weigh continuously and are subject to a wet environment. I was almost sure that one of them would be off but when I placed the weight on the scales, they all read "100" grams.
Even the new scales I picked up yesterday were on the money - though the one that weighs to the hundreth of a gram measured "100.12" grams. Hmmm, I'm starting to worry about that .12 gram.
I'm now on the lookout for a proper Bentley so I can join the ranks of dealers worldwide.
