My FI and I are both geologists, most of our friends are too. We thought it would be cool to give out little chunks of amethyst as favors. I come from a little Canadian town right next to a big amethyst mine and you can buy it at less than a dollar for a small low grade rock at the little shop not a mile from my parents’ house. Quartz is sort of our underlying theme and I'm giving his family a clock what is made from a polished slice of quartz, I haven't decided what variety yet. We are also making centerpieces with really mature sand (therefore quartz rich) and rocks from all the places we have worked so it won't be something random.Would our non-geologist friends and family think this tacky, cheap or just plain un-cool? We were going to have them at each place setting so people would know they are for them. So far everyone we've asked (we want everything secret from most) have said "whatever you want" which is making us worried they think it's a little too geology-nerdy and won't appreciate it.

Re: Geology favors?
I do not put this in the tacky column at all, but I do think the majority of your guests have no need for a piece of amythyst.
[QUOTE]In all honesty, I'd rather have the chocolate. It is a cute idea but your favors should be something your guests will want to take home rather than only something that reflects what you do for a living. I dont' want to sound harsh or anything, but I think you will have a lot of amythyst (which I think is pretty) left on tables. All it would do in my house is collect dust and it serves no purpose.

I think that is a good risk. I would probably take the amethyst and H's and think that I could make some jewelry with it. Then it would sit on my dresser for about a year... and then I wouldn't know what to do with it.
Have you considered chocolate rocks? <a href="http://chocolaterocks.com/" rel="nofollow">http://chocolaterocks.com/</a>
Or rock candy?
That would still fit in your theme.
