Amethyst characteristics

キャッツアイThe Japanese name for amethyst isamethyst crystalMany people probably imagine amethyst as a purple gemstone.
Its clear color and elegant, noble impression make it popular as a power stone. It is mainly produced in Brazil, but is also mined in various parts of the world, including Japan.
Originally, amethyst was as precious as rubies and sapphires, but mines were discovered in Brazil and it began to be produced in large quantities.
It is often thought of as being solid purple, but there are also clear green varieties, which are called green amethysts.
Yellow quartz is also known as citrine, and ametrine is also famous as it is a mixture of amethyst and citrine, creating a beautiful contrast.


The origin of amethyst

The name amethyst comes from the Greek word "Amethustos," which means "not getting drunk." There is an anecdote that says that even if you pour wine into an amethyst glass and drink it, you won't get drunk.


The effects of amethyst

The stone's word is "Sincerity, peace of mind, nobility".
Anti-drunken stoneAmethyst has been said to be a stone that brings good fortune in the home and in love, but in addition to its noble image of purple, it is also famous for its meaning of "staying calm without losing sight of yourself." It is used as a stone that helps you stay calm and improves your luck in family and love.
This gemstone is recommended for those seeking peace of mind.


Caring for Your Amethyst

Amethyst is relatively fragile and may fade if exposed to sunlight for a long time, so after use, wipe it with a soft cloth and store it separately in a jewelry box to avoid contact with other jewelry.
To clean, fill a cup with lukewarm water and add a small amount of mild detergent (dishwashing liquid). Then, dip a soft brush (such as a toothbrush with soft bristles) in the detergent and gently scrub the amethyst. Scrubbing can scratch the amethyst and loosen the prongs holding the stone in place, so it's important to scrub gently. Once you've finished scrubbing, rinse the amethyst with lukewarm water.
It is also recommended to use an ultrasonic cleaner to remove fine dirt, but if the amethyst has been dyed, it is best to avoid ultrasonic cleaning.

2.Chrysoberyl Cat's Eye

Characteristics of Chrysoberyl Cat's Eye

クリソベリル・キャッツアイChrysoberyl is the name of a mineral, and alexandrite, one of the three rarest stones, is one of these minerals. Chrysoberyl stones themselves are green, yellow, or brown, but when they are cut into a rounded cabochon, a ray of light shines through it, making it look like a cat's eye, and this is called a chrysoberyl cat's eye.Looks like a cat's eyeThis effect is called the cat's eye effect (chatoyancy), and stones that exhibit this effect are called cat's eye stones in Japanese. The true nature of this cat's eye effect is due to inclusions within the mineral.
The cat's eye effect can be seen in chrysoberyl, alexandrite, and tourmaline, but chrysoberyl cat's eye is traded at the highest price.
Honey yellow, a greenish yellow like honey, with a clear cat's eye effect is particularly popular.
It is produced in limited areas, with India, Sri Lanka and Brazil being the main producing areas.


The origin of chrysoberyl cat's eye

The name chrysoberyl is a combination of the Greek word "Chrysos," meaning gold, and the element "Beryllos," meaning beryl. As mentioned above, the name "cat's eye" comes from the cat's eye effect (chatoyancy), which causes a ray of light to appear like a cat's eye.
It is a mysterious gemstone that is naturally occurring and became popular after Queen Victoria's son, the Duke of Connaught, gave it as an engagement ring in 1879. After the war, chrysoberyl cat's eye was also purchased in large quantities in Japan, along with opals and jade.


The effects of Chrysoberyl Cat's Eye

The stone's word is "Astonishment, protection, compassion".
Eyes that see the truthThat's why it is well known as a talisman to ward off evil.
The light of the cat's eye is also said to attract good fortune and prosperity, bringing happiness to the owner while remaining natural.
This course is recommended for managers and those in an environment where leadership is required, as well as those who want to improve their interpersonal skills.


Caring for Your Cat's Eye Chrysoberyl

It is heat resistant and a hard gemstone, so it is relatively easy to handle, but because it is a rounded cabochon cut, there is a risk of scratches when hard stones rub against each other. For this reason, it is best to store it away from other jewelry.
To clean, fill a cup with lukewarm water and add a small amount of mild detergent (dishwashing detergent). Then, dip a soft brush (such as a toothbrush with soft bristles) in the detergent and gently tap the stone to clean it. If you scrub, the prongs holding the stone in place may come loose, so it's important to tap the stone. Once you've finished washing, rinse the garnet with lukewarm water.
We also recommend using an ultrasonic cleaner to remove any fine dirt.
