Chrysoberyl is typically formed in metamorphic rocks under high pressure and moderate temperatures. It can also occur in pegmatites and alluvial deposits. The presence of beryllium-rich fluids interacting with aluminum and oxygen is key to its formation.
You can find beryl in pegmatite rocks and in granite deposits, while chrysoberyl is typically found in mica schists and in pegmatites associated with aluminum-rich rocks. Brazil, Colombia, Russia, and Madagascar are some of the countries known for their beryl and chrysoberyl deposits.

An alexandrite is a form of chrysoberyl which displays a colour change dependent on the light source, with strong pleochroism.

Alexandrite is a type of chrysoberyl mineral with a smooth, vitreous texture. It is typically transparent to translucent with a high level of clarity, giving it a reflective and lustrous appearance.

The mineral or gemstone chrysoberyl is an aluminate of berylliumwith the formula BeAl2O4. THe word comes from the Greek words for gold and beryl.
Ex.: emerald, mallachite, chrysoberyl
Alexandrite is the "scientific name" of the mineral.Alexandrite is a type of chrysoberyl (formula BeAl2O4), which may be what you were asking. Alexandrite is specifically chrysoberyl with some of the aluminium atoms replaced with chromium.
You can find beryl in pegmatite rocks and in granite deposits, while chrysoberyl is typically found in mica schists and in pegmatites associated with aluminum-rich rocks. Brazil, Colombia, Russia, and Madagascar are some of the countries known for their beryl and chrysoberyl deposits.
The correct spelling is chrysolite (the gem chrysoberyl, or the mineral olivine).
The most important minerals of beryllium are: bertrandite, beryl, chrysoberyl, phenakite.
