Beautiful colored gemstones capture the attention of all who see them. That bewitching sparkle is an indispensable element of Imayo's jewelry. In the 1960s, fifth generation Nobuhiro Imanishi scaled up imports of precious stones such as emeralds, rubies, and sapphires. By bringing these rare stones to Japan, Imayo introduced Japanese women to the wonder of real gemstones.
Separating good stones from bad calls for a particularly discerning eye. Over the years, Imayo has cultivated strong relationships in countries where gemstones are found, giving us access to the highest quality stones through our own private routes. The stones are then placed in the capable hands of our expert jewelers to be imaginatively transformed, adding color and sparkle to modern women's lives.
As if burning with passion, a ruby shimmers like a glowing red flame. Found only in certain regions of the world such as Myanmar, Thailand, Sri Lanka and Mozambique, we specially select our rubies from regions known for producing the most beautiful stones, which are considered rare and highly valuable. Stones of the richest, deepest red are known as "pigeon's blood rubies" and are the most prized.
Said to be endowed with divine power, sapphires have been cherished since ancient times. Formed from corundum, the same mineral as a ruby, a sapphire is blue corundum while red corundum is a ruby. Any other color comes under the umbrella term "fancy sapphire." These gems can be found in an infinite number of colors. The most precious colors are clear blue, purplish cornflower blue, and deep royal blue.
Said to be the favorite stone of Queen Cleopatra, emeralds symbolize immortality, trust, and purity of heart. Clear gems with a rich green pigment are the most valuable. Colombian emeralds are prized for their deep, dark green color. Emeralds with such deep, dark green pigmentation and without impurities are exceedingly rare.
Only rarely do rubies, sapphires and other gems formed of corundum feature a shimmering six-rayed star at their center. This effect is known as asterism. Gems displaying asterism are extremely valuable.
Gems exhibiting the cat's-eye effect, or chatoyancy, contain luminous streaks that give them an uncanny resemblance to a cat's eyes, hence the name. While the term "cat's-eye" usually refers to chrysoberyl, several other variations exist. "Honey and milk" cat's-eyes, which feature a milky white streak in a rich honey-colored stone, are the most valuable.
Alexandrite is popular due to its mysterious color-changing properties. The stone appears to absorb sunlight and fluorescent light, taking on a blue-green hue, while in candlelight it changes to an enchanting purplish red. The stones that undergo the most dramatic changes in color are the most valuable.
