An elegant petite cushion presenting as near-colorless with just the faintest pale lavender-pink body color in natural daylight - pristine, diamond-bright, and almost invisible as a colored stone at first glance. Its true character emerges under UV light: under 365nm longwave UV this small gem blazes a brilliant, intense red-orange, a strong and vivid fluorescence response that transforms it from a quiet near-colorless stone into a glowing ember. The contrast between its subtle daylight appearance and its fiery UV response is genuinely remarkable for a stone of this size.

From Mae Sai, Thailand, completely untreated, the strong red fluorescence is caused by trace chromium and is a completely natural, unenhanced optical property of this spinel variety. This makes the stone a standout piece for UV gem collectors, gemology enthusiasts, and anyone building a UV-reactive gemstone collection. It is also, of course, a tiny and beautiful gem for minimalist jewelry where the UV surprise remains a private delight.
