Why might it be important for a mineralogist to distingish between a ruby and a garnet?
They are two completely different stones to start with. While there are garnets that have a deep red color it has more of a brown cast to it and, owing to its chemical composition being mainly silicon and oxygen, is softer than ruby. While Garnet is used in jewelry it is a semi-precious stone.
Ruby's chemical structure is based on aluminum an oxygen and ranks 9 on Moh's Hardness scale, just under diamond. Ruby is classed as a precious stone and, depending on the quality, may cost as much as diamond.
Short answer is, if a mineralogist mistook garnet for ruby or ruby for garnet, and was verifying a sale, he could cause a loss of money on either side.

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.
Why are rubies red and sapphires blue?
Both rubies and sapphires are made of corundum (aluminum oxide) which is colorless on its own. Ruby is made red by trace impurities of chromium. Sapphire is made blue by titanium and iron. However, sapphire does not have to be blue. Any gem-quality corundum crystal that is not red is considered sapphire.
The price of rubies can vary widely based on factors such as size, color, clarity, and origin. As of recent market trends, high-quality rubies can range from a few hundred to several thousand dollars per carat. Exceptional specimens, especially those with deep red color and minimal inclusions, can fetch tens of thousands or even hundreds of thousands of dollars. It's best to check current market prices for the most accurate valuation.
