What is more expensive type of ruby
When it comes to prices, ruby stones are only beaten by Diamonds. Rubies have much higher sale prices as well as achieve prices in comparison with Sapphire or Emerald. The reason behind it is the beauty of ruby as there is no other match of 'pigeon blood' like deep rich red colour found in the rubies. When it sold at auction, Sunrise Ruby broke the two world records. First, the most expensive coloured gemstone (apart from a diamond) and second, the most expensive price per carat of any Ruby.
Most expensive type of ruby: The sunrise ruby
When there is a discussion about the World’s Most Expensive Ruby, then the king is "The Sunrise Ruby". Before being beaten by the Crimson Flame, it held the title of the highest price per carat for just over six months.
Over 10 carats bigger than it’s rival, the Sunrise gemstone is an exceptional Ruby.
In 2015, when it was sold, sunrise stone smashed the previous record the Graff Ruby set in 2014. It will be very interesting to see the next gemstone which will dethrone it from the title of the world’s most expensive Ruby gemstone. According to the Gubelin gem report appendix about the Sunrise Ruby:
Gübelin Gem Lab Report mentioned that the 25.59 ct ruby possesses a combination of outstanding characteristics. This gemstone displays richly saturated and homogeneous ‘pigeon blood red’ colour which made it as the finest of other gemstones. Even everything in the gemstone contributes to the beauty of this gem such as the combination of depth of colour with high clarity and brilliance. The finely proportioned cut and shape of this gemstone provides vivid internal colour reflections. Moreover, this remarkable sunrise ruby gemstone has also been spared thermal treatment.’
