Alexandrite Crystal from Hematita, Minas Gerais, Brazil, is a collector-grade oxides specimen prized for rare chrysoberyl crystal with the collector allure of natural alexandrite from a respected Brazilian source. The chrysoberyl with alexandrite association formed in pegmatitic and metamorphic environments where beryllium-rich chemistry and chromium traces combined under unusual geological conditions, giving the piece the geological credibility serious mineral buyers expect when they search for alexandrite crystal for sale or Brazil alexandrite specimen. Display appeal comes from a compact crystal form with strong body color, excellent rarity appeal, and the kind of gem-mineral crossover that attracts both specimen and gem collectors, while the measured dimensions of 2.8 x 2.1 x 1.8 cm and weight of 18 grams place it in an easy-to-present thumbnail format for shelves, cabinets, and focused mineral photography. Collectors value material from Hematita, Minas Gerais because Natural alexandrite is prized because supply is limited, provenance matters, and the species sits at the intersection of rarity, gemology, and mineral collecting. Brazilian alexandrite crystals are never commodity material; even small genuine examples are purchased for authenticity, locality, and long-term collector relevance. For buyers comparing authentic locality material online, this specimen combines provenance, aesthetics, and realistic pricing in the way strong mineral catalog pages should: with accurate data, natural-crystal context, and real collector appeal.
