There are many man-made crystals, some of them imitating natural crystals. In some cases only a specialist can tell the difference between a natural crystal and a synthetic one, like in the case of gems for example. But is it possible to create a perfect replica of a natural crystal?
Nowadays we have 3D printers and they are getting better and better at constructing intricate objects layer by layer and dot by dot, following a computer generated model. The material of choice is usually some sort of resin hardening by exposure to UV light. What if in the near future 3D printers will also work with materials natural crystals are made of and become more accurate and cheaper to use? Accurate enough to make a perfect replica of your favorite one of a kind mineral specimen. Or maybe to make a surreal crystal combination out of this Earth?
What do you think? Could that be? What impact might that have on mineral collecting?

Hi David!
The issue is: what do you mean by replica? if you mean a synthesis, as well as in case of gemstones, there is a long history of research, thus keeping present a synthetic emerald IS an emerald from a pure mineralogical point of view. If you mean an imitation ( like glass for instance), then you can do everything you wish and call it replica! But a mineral collector usually wants TRUE specimen and not "replicas". A fossil collector may be satisfied of a replica if well done, expecially if the original specimen belongs to a famous museum. A gemmologist may be interested to synthesis and imitations, even because he/she wants to study and analyze them. Take it just as an opoinion.

That does raise an interesting question. Could we print copies of our favorite specimens, or of ones we love in another collection? I am sure we could get the shape correct (using scanning technology?) but how on earth (pardon the pun) would we get the color and transparency right? Since we would not print in the right material it could never be perfect.

A copy of a good crystallised specimen can be helpful for study and educational purpose.
As a collector I will never put copies in my collection. I'm collecting minerals, no copies.

One of most fascinating characteristics of mineral specimens is its imperfection compared to ideal geometric pattern. Gloss, striation, texture, inclusions, etching, crystal defects, ... a lot of small details that can not be faked easily. To manufacture a imitation enough convincing to mislead an expert would be very very more expensive than the true specimen itself.
