New Unheated Blue Sapphire Loose 0.231ct Rare Stone from Yogo Valley, Montana, USA [Escole]
Product description This 0.231 ct natural blue sapphire comes from Yogo Valley in Montana and has a special background among sapphires. An analysis report from the Japan-German Gem Research Institute has confirmed that the sapphire is from Yogo Valley, Montana, and that it is an unheated sapphire with no traces of heating.

In recent years, the amount of common Montana sapphire in circulation has increased due to an increase in new supply, and prices have also tended to be lower than before. On the other hand, Yogo sapphire continues to maintain a stable rarity even today because its production areas are extremely limited and new supply is limited. Even within the broad category of ``Made in Montana'', sapphires from Yogo Valley are attracting attention from collectors as they have value and a story to their origin.

Another thing to note about this stone is its beautiful color. Yogo sapphires often come in blues with purple or violet undertones, but this one has a neat straight blue tone that doesn't give off a strong purple tinge. A bright blue light rises from the deep blue, giving you a fun look with rich shades depending on the angle.

Weight is 0.231ct, size is 5.01 x 3.01 x 1.90mm. Finished with an oval modified brilliant cut. Although it is small, it is a rare stone that combines the charms of being "produced in Yogo Valley," "unheated," and "straight blue." It is a highly collectable natural blue sapphire that can be safely recommended to those who are looking for Yogo sapphire with an emphasis on its provenance, as it comes with an analysis report from the Japan-German Gem Research Institute.
