What is an unheated ruby? What are its types and how to choose them?

Ruby Basic Information

Ruby is the well-known red gemstone. Ruby, sapphire, and emerald are the three most famous gemstones in the gemstone world, and all of them are highly popular.

In Japan, the song "Ruby no Yubiwa" (Ruby Ring) sung by singer Akira Terao became a big hit, which further deepened the familiarity of rubies. If sapphire is the prince of the gemstone world, ruby can be said to be the queen of the gemstone world.

Two Types of Ruby: Heated and Unheated

What is heat treatment?

Rubies are broadly divided into two types : heat-treated rubies and non-heated rubies . If we were to compare this to a woman, heat-treated rubies would be like "wearing makeup" and non-heated rubies would be like "no makeup."

Approximately 90% of rubies on the market have been heat-treated, with unheated rubies accounting for only 10% of the total, making them highly valued due to their rarity.

Which is better, heated or unheated?

Heat treatment is carried out to bring out the inherent beauty of rubies. On the other hand, the appeal of unheated rubies is that you can enjoy their natural color and brilliance. However, since there are some unheated rubies whose color is ambiguous, it cannot be said that heated = bad and unheated = good .

Points to consider when choosing a ruby

When choosing a ruby, the following factors should be considered first:

1. Favorite Color : Find your favorite shade, such as bright red or deep red.
2. Cut and shape : Choose a cut that has beautiful proportions and brilliance.
3. Heated or unheated : Find out which treatment your chosen ruby has undergone.

Ultimately, it's best to choose a ruby that you like based on appearance and intuition. It's important to find the ruby that is most attractive to you, without being too concerned about whether it is heated or not.
