Untreated (Natural)Almost all purple spinels on the market are natural and untreated. Their natural brilliance and color require no enhancement. This rarity of being untreated increases their value and desirability.
Heat Treatment (Very Rare)Heat treatment is extremely rare for spinels as it does not reliably improve their color. In fact, heating can darken the color and reduce the stone's appeal. Must be disclosed if applied.
Certification RecommendedFor high-value purple spinels, a laboratory certificate (GIA, GRS, SSEF) confirming natural origin and absence of treatment is strongly recommended.
