The most important factor when determining a ruby's value is it's color. Garnet-like, dark rubies and light colored, almost pink looking rubies, offer the most value. Large rubies of a high quality are extremely rare and the most prized. Clarity is also a very important factor, "crystal clear" is the ideal, meaning you should be able to see through the ruby without hindrance. A cut ruby should have good symmetry and shine. Look out for such words as "created" or "cultured", they mean synthetic, or man made. If a jeweler says the ruby is natural, get it in writing.
There are so many variables when pricing a ruby that your question does not have a simple answer. When it comes to gold all you need is the weight and the carat strength to get your price. And with gold your price will change on a daily basis because the price of gold changes daily. As for rubies color is the biggest determining factor for quality. A deep red color being best. Clarity or brilliance is important. Rubies can be much more expensive than diamonds. Nature makes every stone unique which is why you can't just put a price tag on precious stones. Where an ounce of gold is $1657 on 8/29/2012, the price of a 1 carat mediocre ruby could be about the same depending on the seller and what he/she paid for the stone. When pricing jewelry it is best to shop around.
Please be specific. There's no one answer for that. A low, .1 carat ruby of low quality, is essentially garbage. A high quality, good color ruby that's in excess of 10 carats in a single gem, can stack up into the hundreds and thousands per carat. It all depends on those important factors! There are some nice guides online, take some time to read them. Buy books. Educate yourself; Always worth it.
