[pc.cumGem]

[Fenoxo]

A variant of [pc.cumColor] proposed by Zeikfried, only instead of color, reports a gemstone color.

Obviously cum would be pearl - "She gratefully allows you to craft a pearl necklace upon her collarbones."
Honey could be amber, etc.

Feel free to toss suggestions for the colors of the rainbow and I'll check back in when I get to this!

Oh man this is a great idea.

Uh, uh. What colors do we even have in the game? White and yellow?

• Green = Emerald / Jade
• Yellow/Honey = Amber / Citrine
• Black = Obsidian / Onyx
• Red = Ruby (Because who doesn't want to shoot red fluids out of their dick?)
• Blue = Aquamarine / Sapphire

Seems like a good idea, I'd probably use it. Not sure if you want additional, 'mineral-ish' adjectives here, so I'll throw in a few extras.

• White: Pearl, Moonstone 
• Yellow: Citrine, Zircon
• Orange: Amber
• Green: Emerald, Jade, Peridot, Tourmaline
• Blue: Sapphire, Aquamarine, Turquoise
• Red: Ruby, Garnet (Whoever heard of red cum? So guro.)
• Purple: Amethyst
• Pink: Rose quartz, Rubelite (Best I got)
• Silver: Silver?
• Black: Onyx, Obsidian 

... Drat. Savin just beat me to it!

I'll just list a couple for each of the existing fluid types. Of course not all of them have to be defined, but just to cover all the existing bases:

• Milk: white alabaster, white opal, white sapphire, white jade
• Honey: amber, golden topaz
• Cum: pearl, white opal
• Oil: black diamond, onyx, lodestone
• Milksap: jasmine, jonquil, ivory gold
• Girlcum: crystal, morganite
• Cumsap: pearl-marbled amber, yellow tourmaline
• Chocolate Milk: smoky quartz, chocolate opal
• Strawberry Milk: rose quartz, pink sapphire, umbalite
• Sydian Cum: silver, gray tourmaline
• Vanae Maiden Milk: pink topaz, pink pearl
• Vanae Huntress Milk: amethyst, violet opal
• Nectar: citrine, topaz
• Leithan Milk: white diamond, milk quartz
• Vanilla: white moonstone, pale sunstone

As for a generic rainbow of gemstone colors: garnet, ruby, carnelian, topaz, citrine, chrysolite, peridot, emerald, jade, turquoise, aquamarine, sapphire, amethyst, alexandrite, pearl, opal, moonstone, diamond, lodestone, bloodestone.

Some are pretty specific and some gems have multiple possible colors. These can be combined/interchanged. Normal colors tend to overlap gem color names too. Hope this helps though.

Two more I thought of. (I know Turquoise is already used for blue, but still.) 

• Teal: Turquoise
• Rainbow: Opal (this one's just for shits and giggles)

 

[Spikes]

Green: Malachite

Blue: Lapis, Kyanite

I've found this website that has a huge amount of lists of gems, one of them by color. (I'll definitely save it for later.)

From there I picked the best examples for generic colours:

Clear - Diamond, Clear Quartz
White - Pearl, Milk Quartz
Pink - Rhodonite, Rose Quartz
Red - Ruby, Garnet
Orange - Amber, Citrine, Carnelian
Yellow - Topaz, Gold, Amber, Pyrite
Green - Emerald, Jade, Peridot, Malachite
Blue - Sapphire, Opal, Aquamarine, Lapis Lazuli, Turquoise
Purple - Amethyst, Sugilite
Black - Onyx, Jet, Obsidian

I used the same list to compile this one, collecting the various fluid colors from the code and trying to associate gems with them:

Milk/Cum/Vanilla: White/Alabaster/Ivory
    Pearl, Milk Quartz
Honey/Nectar: Amber/Yellow/Gold/Tawny
    Amber, Gold, Topaz, Pyrite
Oil: Semi-transparent/Translucent Brown/Lucent
    Citrine, Brown diamond
Milksap: Whitish-Yellow/Ivory Gold/Off-White
    Gold Pearl, Yellow Diamon
Girl Cum: Translucent/Clear/Semi-transparent
    Diamond, Clear Quartz
Cumsap: Off white/Pearl-Marbled Amber/Ivory-Amber
    Pearl, Milk Quartz
Chocolate Milk: Chocolate/Creamy Brown, Chocolate/Dark, Chocolate
    Citrine, Brown diamond
Strawberry Milk: Pink/Creamy Pink/Light, Pink
    Rhodonite, Rose Quartz
Sydian Cum: Silvery/Metallic Silver/Silver
    Silver, Platinum
Vanae Maiden Milk: Pink/Milky-Pink/Pink-marbled Cream
    Rhodonite, Rose Quartz
Vanae Huntress Milk: Violet/Milky VioletViolet-marbled Cream
    Amethyst, Sugilite
Leithan Milk: Alabaster/Semi-Transparent/Off-white
    Pearl

And a few not yet in game that might come in the future:

Goblin Cum: Green - Emerald, Peridot, Malachite
Fanfir Cum: Orange - Citrine, Carnellian, Amber
