Not sure if it is an issue with Silent Gems or LIT, but I ended up crashing. I am going to Gist it so it isn't so long on this page. I am not willing to pay for a Pro Subscription on Pastebin...

Essentially what happened is I had crafted the Supercharged Peridot Boots in an Improved Crafting Table (from LIT). Trying to retrieve my boots from the crafting table immediately kicks me out of the game (Exit Errorcode 1). Attempting to retrieve anything out of the table at all has resulted in a crashed game.

I can confirm that the crash also happens with the vanilla Crafting Table too. Trying to get the Supercharged Peridot Boots from the crafting table immediately crashes Minecraft and boots me out. Trying to retrieve my items out of the crafting table (gems, boot pattern, etc) also crashes Minecraft. The only way to get my armor back is to destroy the crafting table.

Never mind... being that I don't use Curse (I use MultiMC), I didn't realize that there was a newer version out that fixed that issue. No action needed.
