What are some very beautiful gems?

There are plenty of beautiful gems, but based on valuation (a combination of perceived beauty and rarity) the top 3 might rank roughly like this:1 - Red Diamonds2- Blue Diamonds3 - Pink DiamondsYellow Diamonds would probably be next, and then large White Diamonds after that. However, many top emeralds (green) and sapphires and rubies have more value per carat than a typical white diamond. Alexandrite is another very prized gem, and this is not only due to its color but the fact it changes color in various lighting (from purple to green typically).Those are the major, high value and thus as voted by money, the most beautiful gems. The reason diamonds rate so highly is they have a very high 'light bending ability' (better termed as refractive index) and this is what lets them bounce back so much light making them have the sparkle and fire that people view as beautiful. The colored diamonds combine the best of the colored gems but with the fire inherent to diamond and that combined with their extreme scarcity makes them highly prized.Of interest, you may start to see a few more real blue diamonds around. Lab grown blue diamonds are slowly starting to become available and these are real diamonds, grown with boron just like mined blue diamonds. It will not affect the value of the mined blues, but it does offer a chance to own a real blue diamond for thousands per carat instead of hundreds of thousands per carat, something that was not possible before.A video of a lab blue diamond ring is on the link section below, and also a page for lab grown green emeralds that are grown in the same style as mined natural colombian emeralds. The colombian emeralds are prized for their slight blue hue to the green, which is caused by vanadium.
