Unheated Ruby in Hong Kong

The ruby is one of the world’s three largest gems. The key to evaluating the investment value of rubies lies in their “colour” and “origin”. Therefore, after certification, a unheated ruby ​​with a strong colour is ten times more expensive than a heated ruby. The investment value of rubies continues to rise after the closure of ruby mines. In Hong Kong, rubies are undoubtedly a valuable investment, especially unheated ruby ​​rings, which are hard to find.

Most rubies available in the gem market have undergone heat treatment. Unheated ruby ​​refers to the pure natural ruby ​​that has not been heated, which is quite rare in Hong Kong. With the depletion of mineral resources, the rubies produced today are not as bright as they used to be. From a gemological point of view, natural or unheated rubies have an opacity that requires heat treatment processes to transform the color and clarity and be good enough to be faceted into gems. "Pigeon Blood" is the most popular heated ruby. The price of unheated rubies in Hong Kong is higher than the price of heated or treated rubies, with the emphasis on the rarity of the gems.

Statistics show that unheated rubies have soared by 300 to 500% in the past 5 years. In actual auctions, an 8.62ct unheated Graff ruby was sold at 25 million yuan in 2006. Eight years later, in 2014, its value went up to 60 million yuan at the auction. Unheated rubies definitely have investment value in Hong Kong. Special occasion jewellery such as wedding rings inlaid with a natural or unheated ruby on the band will bring a unique elegance and timelessness to your special day – a treasure that can be passed on for time to come.
