Does anyone know of any random gemstone generation tables (along with their half carat value) for Rifts? I want to be able to roll up random gems for the games I'm GMing at the moment, to help the mechanic of the group.

For Rifts, no.

The Hackmaster GMs Guide had the best one I ever saw, if you can get a hold of a copy.

The best way I have found to do this is I simply made a list of the prices of gems, from smallest to largest.
I then roll up the value of the horde, and look on the list to see what gems fall in that range, and either pick or roll to see what that is

So if I roll up that the party finds 30,000 in gems and that its 10 cts I need something that is going to be around 2-3,000 per ct (I can fudge the number a bit because a single large gem is going to be much more valuable than multiple small ones)
I look at the list and Clear Zircon, Malachite and Black Garnet are all 2,500 per ct.
Presto I decide that they find a flawless 10ct deep black garnet and that it has a 'market value' of 30,000

I have done slightly different as well.
For example, the group finds a huge cache of diamonds in ruined vault. I decide that it is worth 5,000,000 cr but that it is going to be in .25 ct stones.
rounding that is 1334 tiny little diamonds to keep track of. But if they don't loose any of them they are going to have a nice payday once they find someone to off load them onto with out crashing the market.

Thanks for the suggestions, folks.

i played a game once where the players got paid in a bag of gems, without giving them any information, i had each player roll a D4, the color of the die the player choose to roll represented the gem and the number on the die determined the worth of the gem in the bag, this was fun because most players have several dice to choose from, so what every random color they choose was the gem,

I like this. I like this a lot. Consider it borrowed.

Diamonds and emeralds can also be used to store P.P.E. energy. The gem must be at least one carat and can hold as much as 25 P.P.E. points. To charge the gem with energy, the mage must meditate at a ley line nexus or stone pyramid and channel some of its energy into the gem. The entire process takes about 10 minutes. Gems used as P.P.E. storage batteries can be used only as a battery (cannot be drawn upon for magic powers). The energy can be drawn on at any time by the stone master as long as it is in his possession. The gem can be charged up to six times before crumbling.

Note about precious gems: Precious gem stones tend to cost much more in the world of Rifts than in our modern Earth, because they are far less accessible. Gems are typically found only in certain places in the world and may be very difficult to acquire. Rubies and sapphires of all kinds are especially rare in North and South America and Europe. The are found primarily in Burma, Thailand and Sri Lanka (they are typically 40% less expensive at those geographic locations). Emeralds are found mainly in Colombia (South America), Egypt, and South Africa, Aquamarine is found in Brazil, Colombia, Siberia, and the Urals (Russia). Diamonds are most abundant in South Africa. Brazil, Venezuela, and found to a lesser degree in all of Africa and parts of Colombia, Mongolia, Siberia and the Urals (Russia). Synthetic diamonds and synthetic zircon (man-made) do not work for magic.


Your problem to make a random table or whatever.

No, that's not it. The original Hackmaster v.3.25 had rolling tables to determine the gem type, size, clarity, imperfections, etc. You could roll anything from a tiny, badly flawed bloodstone, to huge, perfect diamond. It even allowed you to calculate the base value of the gems based on those rolls.

not gonna find the old version. unless maybe someone on ebay is selling it for eight hundred dollars.

I lied. It took about 20 minutes of digging.
