I can relate to Lynn, I have a lot of larger specimens scattered throughout the house. I have probably over 30 pieces now, in just about every room. I actually went out and bought 3 accent tables made of mango wood, of staggered heights to display a set of 3 in my living room. One has a 30 lbs citrine, a 22 LBS calcite with pyrite, and a 15 lbs clear quartz chrysanthemum. It's becoming a bit of a sickness actually, but my wife still indulges me, what a sweetie !
Got black quartz and kyanite on my dresser, labradorite on my kitchen counter, a huge andradite garnet and red quartz on my dining room table, hell I even have specimens on my bathroom counter ( large rose quartz and green fluorite )
I think maybe I'm subconsciously trying to create some kind of museum.
My wife collects smaller but expensive quality tourmaline. She has them on a coffee table, but the table is covered with a mirror. This refracts the lights better of course and also makes the collection really stand out.
