Chrysoberyl found in the Ilakaka deposit include vivid yellow-green and of the cat's eye variety and small quantities of alexandrite with a very good color change. Occasional large alexandrite crystals of gem quality were recovered in Lake Alaotra.
In recent years, it has become more difficult to get information on the mine situation in Myanmar (formerly Burma), because the country has become so closed. There are many new small private mines, which appear northeast of Mandalayr. To the west of Mogok, near the Kabaing granite intrusions, many pegmatites and some hydrothermal veins occur, especially in the Sakangyi and Barnardmyo areas. From there occasional finds of yellow chrysoberyl and alexandrite have been reported in recent years.
