The jewelry brand ‘Minas Alexis,’ operated by the Estelle Holdings Group Co., Ltd. (Headquarters: Chuo-ku, Tokyo), is launching new alexandrite jewelry.
Alexandrite, also known as the birthstone for June, is a mysterious and rare gem that changes color between day and night. It exhibits a ‘color change effect,’ appearing bluish-green in sunlight and reddish-purple under incandescent light at night. Due to its rarity, it is also called the ‘king of gems.’
The new collection being launched uses alexandrite from the Minas Gerais state in Brazil, which is considered the highest quality among alexandrites worldwide. Alexandrite from Minas Gerais is renowned for its vivid color change and beautiful coloration, captivating many gem enthusiasts.
‘Minas Alexis’ is an original collection by As-me Estelle, featuring alexandrite from the Minas Gerais state in Brazil. It maximizes the allure of alexandrite’s mysterious brilliance that changes expression between day and night, offering a wide range of designs from daily wear to luxury pieces. Despite being a rare gem, it is supported by many customers as jewelry that is easy to incorporate into everyday life.
A major feature of Minas Alexis is its system that consistently manages everything from rough stone purchasing to product creation. Rough stones mined in Minas Gerais, Brazil, are purchased directly. Skilled artisans at the company’s own polishing factory in Vietnam then sort, polish, and grade the stones. Afterward, the stones are transformed into products based on original designs by Japanese designers. This integrated production and sales system makes it possible to offer high-quality alexandrite jewelry at fair prices.
