Quartz is a common, attractive natural crystal.

Quartz is a crystal that is found widely in nature. It is common and inexpensive. However, there are many reasons why you might want to make an object that looks like quartz. For instance, while small crystals are inexpensive and common, large crystals are very expensive. You might also want to add crystals to a craft project that can't handle the weight of a real crystal, or you might have children who would like crystals to play with. Resin is an adaptable material that can be used to make fake quartz crystals.


Step 1

Mix the silicone putty according to the instructions, blending the two parts of the putty together in your hands. Mix thoroughly and be sure that the color is consistent. You will only need a small amount of silicone putty.

Step 2

Wrap the putty around your quartz crystal, leaving a space at the top to remove the crystal, and wait for it to set. Setting time varies depending upon the brand.

Step 3

Remove the crystal carefully.

Step 4

Put on your gloves.

Step 5

Mix your casting resin in the plastic cup according to the instructions, adding the correct amount of catalyst. Again, you will only need a small amount of resin for one crystal. Mix thoroughly using the craft stick. If desired, add a few drops of transparent resin dye. Pure quartz is clear, but if you are making toys for children, they may enjoy brightly colored crystals.


Step 6

Pour your resin into your silicone putty mold carefully.

Step 7

Blow gently on the resin to remove any air bubbles.

Step 8

Wait for the resin to set. Resin can take a day or more to completely harden. To make the process go faster, keep the resin in a warm place.

Step 9

Remove the "crystal" from the mold.


Silicone putty is best for making small or shallow crystals. To make a large crystal, you may need to create a two-part mold from silicone. Protect your work surface with wax paper. Work in a well-ventilated area.
