Answer:
Beryllium, aluminum, silicon and oxygen come together to create the mineral Beryl. The right temperature and pressure conditions can be the start of forming emerald. Beryl is typically found in metamorphic rocks and in volcanic deposits or in fractures and cracks in large areas of granite rock.
