Green fluorescent lavender spinel is a very rare and highly prized variety of spinel. The combination of a delicate lavender hue with green fluorescence under UV light is both visually striking and geologically fascinating. This specific phenomenon is caused by trace elements within the gemstone, typically chromium or iron, which influence both the color and the fluorescence. The green fluorescence against the lavender base color creates a dynamic visual effect, making the gem a collector’s item. It is rare for a spinel to exhibit both a soft pastel color and striking fluorescence, adding to its desirability.
