Stage 1 – Normal Light (Resting State)

In regular indoor or daylight conditions, the gemstone appears soft white grey

Stage 2 – UV (Activated State)

Extreme Florescence state

Stage 3 -When exposed to UV light or strong sunlight, the stone deepens into a richer violet-purple, sometimes with smoky undertones. This transformation happens within seconds.

Stage 4 – Fade-Back Phase (Reversion)

Once removed from UV light, when under extreme white light the color slowly fades back to its original grey white tone over minutes to hours — a reversible and repeatable natural phenomenon known as tenebrescence.

NOTE

Weight and size of gemstones may vary slightly due to difference in calibration of weighing and measuring scales.
