the best way too find out is either testing hardness or grams per cubic centimeter

Weight in the air devided by weight in the air - weight in the water = weight in the air devided by volume = grams per cubic centimeter

Although you do need some equipment for that

Wouldn't a kitchen scale and a measuring cup suffice?

Yes if you want to get estimates, but two very similar minerals can weigh similar as well, and then the differences between weighing would just be the inaccuracy of your measuring tools

HCl and a pocket knife is all you need.
