Besides for the extremerly rare Red Beryl, Morganite is the least common gem form of Beryl. Its color tone is usually light pink, deeper pink stones and those with an orange tinge are more valuable. Large clear crystals of Morganite have been found, which have enabled fairly large flawless crystals to be cut from them.
