Alexandrite in Chrysoprase Tourmaline Puntland custom bracelets with names

Diposting di oleh Kingjy

The discoloration effect of alexandrite is the result of its selective absorption of light waves. Its transparent crystal can pass red and green light. Karena itu, under different wavelength light sources, when the light source (such as incandescent lamp) contains more red components, itu akan tampak merah; when the light source (Such as fluorescent lamps or sunlight) the green component will appear green for a long time, so it is known as “emeralds in the day, rubies in the night”. A gem has the colors of two precious gems, showing its preciousness and magic. Alexandrite rarely has crystals larger than a few carats, and its value depends on its color and intensity of discoloration. The value of alexandrite is much lower than that of cat’s eye. There is also a variety that combines the color change effect and the cat’s eye effect, ditelepon “allexite opal”, which is very rare and precious.

Opals in chrysoberyl are generally cut into hemispherical cambered stones to show cat’s eye glitter; while alexandrites are mostly cut and processed into standard round diamond or emerald faceted stones. Because gold emerald has the characteristics of high hardness, ketangguhan yang baik, and strong impact resistance, the two cut gems, alexandrite and opal, are ideal materials for making men’s rings, and they are also used to make pendants and brooches.

Chrysoberyl is usually produced in granite pegmatites in ancient metamorphic rock areas and also in sandstone. There are not many countries in the world that produce golden emeralds. The main producing areas are Sri Lanka and Russia, followed by Brazil, Myanmar, Madagaskar, Tanzania, dan Amerika Serikat. Xinjiang and Sichuan also produce them. The world’s best cat’s eye is produced in Sri Lanka, which is also the only country that produces both cat’s eye and alexandrite. The best alexandrite is produced in the Ural region of Russia, ranking first in the world.
