Free for use at your gaming table, 46 gems big and small generated using All the Treasures of the World: GEMS from Faster Monkey Games. All these gems use the cinematically huge sizes from the Fantasy chart, because massive fist-sized shinies are just more heroic and fun.

Box of Gems
This collection of a dozen stones, perhaps just what caught someone’s eye over the years, includes a single outstanding but hard-to-spot gem, plus a handful of lesser stones, for a total value of 1,370 gp. The four smallest gems are among the most precious, being flawless; by deciding to use an unusual polished shape on the diamond instead of a faceted cut, we make the four look like a set of loose, spherical beads among the larger stones. (Generated with the full randomization rules.)

• A smooth, heavy egg of light green stone. [Huge chrysoprase (10 gpv)]
• A clear blue gem with cloudy streaks inside, cut into a faceted heart that fits in your palm. [Huge flawed aquamarine (10 gpv)]
• A metallic grey pearl like a cherry pit, covered with wart-like bumps. [Large silver pearl of very poor quality (25 gpv)]
• A smooth, fist-sized lump of translucent honey-colored material. [Huge piece of amber (25 gpv)]
• A polished, grape-sized, opaque green rock, in some lights barely showing a V or Y of paler color. [Large moss opal, with star, flawed (25 gpv)]
• A chestnut-sized greenish stone with rough patches on the surface and a line of faint sparkles through the most polished part. [Huge green tourmaline, with cat's eye, of very poor quality (25 gpv)]
• A translucent, apple-green dome two inches across with several cracks running through it, showing a faint white line inside. [Huge peridot, with cat's eye, of very poor quality (25 gpv)]
• A flat-backed half-egg shape the size of the end of your finger, translucent pink with a faint grey-white star of six points. [Common spinel, with star (50 gpv)]
• Four little bead-like spheres: A white one that reflects like a rainbow, a transparent one the color of ale, a glossy white one, and a red one like a blood drop with a tiny six-pointed white star in it. [Small flawless opal (25 gpv), small flawless brown diamond (50 gpv), small flawless white pearl (50 gpv), and small flawless star ruby (1,000 gpv).]

The Eye of the Arch-Mage
Twenty inches in diameter and weighing 360 lbs, this is the largest known crystal ball in the world. The sphere would command 500 gp as a gem, and possibly much more in a world where such things can be made magical.

The Prince’s Lost Marbles
Ten of these precious stones share the same size and shape: perfect half-inch spheres. Together with one larger taw or shooter of tremendous worth, they make a set intended for use in marbles games by a very wealthy child. They may be found in a bag of purple velvet or a protective case. Though each gem is of a different type, their precise matching in size and polish adds 20% to their value when sold together, for a total price of 9,750 gp. If the gems are actually associated with a known prince or other noble, the price may increase to 10,000 + (1d6 x 1000) gp, or the state may simply claim them as lost property. (Generated by randomizing 11 precious stone values, randomizing type, and increasing size and value of each until as big as a marble, or bigger for the taw. All have typical Good quality.)

• “Blackie”: Black opal, large (250 gpv)
• “Bluey”: Tourmaline, blue (25 gpv)
• “Creamy”: Lustrous pearl, large (250 gp)
• “Greenie”: Emerald, huge (1,000 gpv)

• “Lord Taw”: Gigantic fiery sapphire, 3/4″ diameter (5,000 gpv)

The Paragon
This famous stone belongs to the richest merchant house: A perfect white diamond, cut in faceted ovoid just over an inch in diameter. Value: 10,000 gp. (Generated to match the real-world paragon class by choosing a 100 carat flawless diamond and finding its size and value from the charts.)

The Dwarvenstone
According to legend, the dwarf kings owned this, the most valuable gem in the world, until driven from their halls by a dragon. The Dwarvenstone, if real, is a perfect white diamond larger than a big man’s two fists together. Its thousands of facets draw in every gleam of light and reflect them back as a pure glow from the heart of the stone. Its gem value is 100,000 gp, but should anyone else possess the Dwarvenstone, the dwarfs will stop at nothing to regain their fabled treasure. (Generated by taking literary inspiration, choosing the largest possible perfect diamond, and finding its value from the charts.)
