About Us

Neptunium is a family-run business specializing in exquisite fossil and fine mineral specimens, proudly based in Jakarta, Indonesia. Our journey began in mid-2021 as a collection shop, founded by our owner, Ryan, who was only 11 years old at the time. What started as a passionate hobby gradually evolved into a more focused and professional endeavor, driven by a burning passion.
