I picked up some silicone mold rubber and resin to make molds of and cast some crystals. Cool thing is, I ordered same day shipping from Amazon and the package didn't arrive on time so they gave me a full refund and told me to keep the products
Never done this before and I'm not sure if I mixed the compounds thoroughly enough, so it may not turn out too well. I'll update later tonight when the silicone has hopefully fully cured.
I am going to try to add some coloring to the resin to get different ones. Possibly even cast one in a color, break it into pieces and then throw those pieces into a clear cast. In my mind that may create a pretty cool effect.
Here's what I'm using and a pic of the mold degassing/curing. Wish I got some pics of the crystal beforehand but I was too anxious to get started. I just hot glued it to the bottom of the cup.

The mold cured so that's a good thing. I put a cut off cup and s piece of tape around it the hold it in place. Then mixed up the resin and poured. I am a little worried about the resin as that has a ton of bubbles in it some are popping but I'm sure a lot will be left over. Now the waiting game. The resin takes 18-24 hours to cure :/

I would call the first attempt a success. I probably could have let it go the full 24hrs because it is still sticky, but I think it is stable enough to fully cure outside the mold. Picks up light very well and the bubbles turned out to be not so bad. This definitely seems like a viable option for rounding out your crystal stock pile.
If you want it ultra clear you have to pressure it when you mold it and when you cast it. Usually to about 80 psi. I've made dozens of clear castings and this is the best method. Also, warm the mold at 100 degrees for 10 minutes.

Now that you mention it, I heard about heating the mold and totally forgot about it. I'll have to give that a try. Thanks! I did use a heat gun prior to pour which seemed to work pretty well on the resin.

So here are the results from today. Not real crazy with the clear one with blue chunks. I have to play around with the idea more. Maybe smaller pieces and definitely need to work out some of the bubbles. Way too many in this instance.
Clear Resin : Blue Chunks : White Led
Red Resin : Red Led (appears much deeper red in person)
Red Resin : White Led (appears much more pink in person)

Those look great. I don't know if you knew it or not but you can shape quartz crystals to any shape and sixe you want them by using a dremel and a diamond dust cut off wheel. It works great. You can even split larger quarts into smaller ones and shape those too. Plus, it is super quick doing it that way. I am in no way saying that yours are not awesome at all, I just wanted to let people know there are other ways to make custom crystals.
