The most valuable ruby in the world is often considered to be the Sunrise Ruby. This exceptional gemstone is a rare pigeon's blood red Burmese ruby weighing 25.59 carats. It displays a rich, saturated color with excellent clarity and is known for its exceptional beauty and rarity.
The Sunrise Ruby set a new world record for the highest price ever paid for a ruby at an auction in May 2015. It was sold at a Sotheby's auction in Geneva for over $30 million, surpassing the previous record held by the Graff Ruby.
It's worth noting that the value of rubies, like any gemstone, can vary depending on various factors such as color, clarity, size, origin, and overall quality. Pigeon's blood red rubies from Burma (Myanmar) are highly sought after and generally command higher prices due to their exceptional color and historical significance.
