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 away from other jewelry.
When cleaning, fill a cup with lukewarm water and add a small amount of neutral 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 stone, it can scratch the amethyst or cause the prongs holding the stone to come loose, so it's important to wash it by tapping it. Once you've finished washing, 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 and a ray of light shines through them, making them look like a cat's eye, they become chrysoberyl cat's eye.Looks like a catThis 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.
In particular, honey yellow with a greenish yellow hue and a clear cat's eye effect are popular.
It is produced in a limited area, with India, Sri Lanka and Brazil being the main producing areas.


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 streak of light to appear like a cat's eye.
It is a mysterious gemstone that is produced naturally, 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 purchased in large quantities in Japan, along with opals and jade.

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, it may be scratched if two hard stones rub against each other. Therefore, it is best to store it away from other jewelry.

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 stone, the prongs that hold the stone in place may come loose, so it is important to wash the stone by tapping it. Once you have finished washing, rinse the garnet with lukewarm water.
