Faceted Prehnite and 'Dark Rainbow Metallic' Beaded Necklace with Magnetic Clasp

This necklace is an 18-inch long, single-strand piece weighing 26.5 grams, featuring a casual yet elegant design. It is primarily composed of numerous light green, translucent beads that appear to be faceted prehnite, which are approximately square to rectangular in shape. These 'greenish clear' beads possess a smooth surface despite their faceting, suggesting a polished finish. Interspersed at irregular, asymmetrical intervals are smaller, dark, often iridescent beads, described as 'dark rainbow metallic stones'. These smaller accent beads appear to be smooth and possibly round or barrel-shaped, creating a unique visual rhythm along the strand. The necklace is secured by a distinctive silver-toned magnetic clasp, which is visible in the provided image and appears to be heavily textured or adorned with small details, contributing to the overall aesthetic. The asymmetrical arrangement of the metallic beads suggests a deliberately modern or 'organic' design approach rather than strict symmetry. The craftsmanship appears to be of good quality, with attention paid to the selection and stringing of the various beads. There are no discernible major condition issues such as chips or cracks visible on the beads, nor any obvious damage to the clasp, although a closer inspection would be needed to confirm the absence of minor wear. The 'dark rainbow metallic' beads add a subtle contrast and contemporary flair to the soothing green tones of the primary beads. This piece likely dates from the late 20th century to early 21st century given its materials and magnetic clasp. It could be considered a modern artisan or contemporary jewelry piece.
