Gimme that loot! Those sweet, shining gems? That's luxury living!
When I was a kid I loved big, fake gems. I was a rock collector and had lots of fine specimens, mostly fossils and amethyst and pyrite, but I wanted the glitzy stuff. Rubies and emeralds and diamonds...
I specifically remember going to the mall with my mom and finding a cheesy plastic bracelet filled with massive fake gemstones. It was at some old lady store, and I spent 8 bucks of my own cash to buy it, so you know it was valuable.
I took it home and immediately pried out all them gems, put them in a steel box, and buried them. Pirate treasure, yo. Pirate treasure.
