Fortunately Intergem doesn't seem to be travelling to Europe any time soon. I've been to a couple of jewellery fairs and walked out a lot poorer than I walked in. But much happier too.
		
		
	 
 I know that experience 
intimately.
First show I went to, I set a $500 budget.  Spent $1000.
The next show I set a $1000 budget.  Spent $1800.
Yada yada yada…
I’m much better at keeping to my budget these days, but it took going to a show a decade or so ago and spending WAAAAAY too much to knock some sense back into me.  Essentially, I had a commitment out of town, and could only attend the first day of the (3 day) show, and was having problems deciding what to buy.  So I 
didn’t decide- I bought 
everything I liked.
Well, 
almost everything.  On my way out of the show, I passed on one newly discovered stone that was exceedingly rare.  The cutter, Bill Vance, had 20+ carats of faceted material for sale, approximately 75% of the world’s supply.  He offered to sell me one of the largest for $3000.  I could have bought it, but the reality of what I had already spent was starting to sink in.  I passed on it.
He sold it about 6 months later for $20k.  
If I had bought it, selling it it would have put me back in the black with plenty of room to spare.  Thing is, I’m not sure I would/could have sold it then. 
To this day, I’ve never sold a piece of my jewelry and only 2 stones I’ve purchased.  What little has left my Draconic hoard were gifts to friends and family.
I‘ve only a couple weeks ago cherry-picked some of my best stuff to sell in order to raise funds.  I photographed them all (badly) and catalogued them for appraisal & sale with the purpose of replacing the decrepit wooden fence & motorized gate of my parents’ house with a metal one so they don’t have to take out a loan to do the work.m Depending on the job bids and what I can get for my stones, we might even add a solar power & storage setup.
But I can already feel myself second-guessing 
my own plan because of how cool some are.
