Stone Slab Appraisal

Banded Fluorite Slab

This item is a large, triangular slab of banded fluorite, often referred to as 'rainbow fluorite' due to its distinct coloration. It measures approximately 10 inches in width and 7 1/2 inches in height. The fluorite exhibits prominent concentric bands of various colors, including shades of deep purple, lavender, olive green, pale green, and hints of brown/gold, creating a striking visual effect reminiscent of topographic lines or ripples. The surface appears polished, giving it a smooth, semi-glossy finish that highlights the internal banding. The edges are irregular and natural, suggesting it was saw-cut from a larger crystal formation and then partially shaped and polished on its primary display faces. There are no obvious signs of significant damage such as large chips or cracks on the main polished surface. Some minor rough areas or natural inclusions are visible, particularly around the apex and base, consistent with a naturally occurring mineral specimen that has been prepared for display. It is presented on a clear, acrylic display stand, suggesting it is intended for decorative or collection purposes. The quality of the banding and the clarity of the colors indicate a good quality specimen. This piece likely dates from the late 20th or early 21st century, given its polished form and common availability as a decorative mineral piece.
