Ag & Cu crystals

Does anyone know a place one can buy silver and copper crystals? I know the process to grow them but don't have the inclination or time. And it probably takes a lot of practice to get nice large ones.

As far as copper, I have two pieces I grew through electrolysis. The 2nd one I let grow for three weeks in a near neutral solution. Are you wanting faceted crystals or dendritic?

*Edited with attached pictures.

These probably aren't even close fo what you are looking for. The thicker one was grown for close to a month on very low current. I was trying to recover as much copper from solution as possible and having high purity, so there isn't anything super exciting about it.

The thinner and darker one was grown for over a week or up to two if I remember. It cleans up nice in hot vinegar.

If you want to drool over beautiful crystals, definitely check out Onyxmet.com
I know of no other like them.

I've got some copper sulfide I recently created. There are some microscopic faceted crystals of either a synthetic covellite or chalcocite structure and composition. It's a nice indigo blue which makes me side with a majority of covellite.
