Make a resin geode that separates into four quarters with this reusable geode design silicone coaster mold.  Your resin will cast with a scalloped edge, making it easy to create a geode look.  Add rocks or glass bits, then paint the edge to help accentuate the scalloping.

Each slice measures 4 inches on the straight sides and 1/4 inch deep.

Great for making matched resin coaster sets to gift or sell!

How do you use this four-part geode mold to make a geode coaster set?

Step 1:  Mix and pour a casting resin.

Step 2:  Make it special by using colored resin and clear resin in the same space.  Add chunky glass and pebbles to create the look of a geode.

Step 3:  After curing, twist the mold while grabbing the hardened edge to remove from the coaster mold.

Resin geode coasters shown were made with clear casting resinResin Obsession transparent blue and transparent green pigment, micro glitter, pebbles, and shaved ice.

Protect your investment!  To prolong mold life, apply a light layer of resin mold release thirty minutes or longer before use.

I just started my business with Resin art and crafts. After so much research, I came across this website that offered a lot of things I needed. The shipping is super fast which all of the things I ordered came in time for my launching. The coasters are so easy to use. I will always use Resin Obsession for my products needs in the future. ❤️

Oh gosh Quinyona, thank you so much!


Great product. Easy to clean, perfect size and easy to demold

These are beautiful Charlene. Thanks for sharing!

Geode mold

I just finished my 1st pour using this mold. I can't wait to demold it tomorrow! The attached picture was taken about 30 minutes after I finished pouring. Love it already.

Very good quality

This was my first geode style mold so I was not sure what to expect. Turns out the mold is quite thick and sturdy. I did a pour and removal was easy. I like the depth as well.
