Newly discovered ruby deposits at Vatomandry and Andilamena are found in which country?

The correct answer is Madagascar because this island nation is known for its rich variety of gemstones, including rubies. The recent findings of new ruby deposits at Vatomandry and Andilamena indicate that Madagascar remains an important source for these coveted gems. The geological conditions on the island create an environment conducive to the formation of high-quality ruby deposits. This discovery contributes to Madagascar's reputation as one of the leading producers of rubies in the world, alongside other notable gemstones.

While other regions in Africa, such as Kenya and South Africa, do have their own gemstone deposits, they are not known for the specific ruby discoveries at Vatomandry and Andilamena, making Madagascar the definitive location for this particular question.
