Steven Universe OST - Gem Shards x Undertale - True Lab Theme Gem Lab is a Undertale x Steven Universe Alternate Universe remix. I really loved this episode. Who else here has created a gemsona? What gem did you pick, and why? Did you make any fusions with your friends? I picked Pink Fluorite because of my favorite manga character (nerd alert) and my favorite color. One of my friends is Opal, so we're Opalized... I'm working on a shield for a Rose Quartz cosplay. I decided to make a test cut of it on a little red 4x4 acrylic square I had, and it turned out really well! The final is gonna be 18x18, domed, paint... Some junk I made the other week. I miss her limb enhancers.
