Blue Aventurine

Blue Aventurine is a captivating and relatively rare variety of aventurine, known for its soft, shimmering blue hue and subtle sparkle. Like its more common green counterpart, blue aventurine is a form of quartz, but its unique coloration comes from mineral inclusions—typically dumortierite or other blue-hued minerals.
