This exquisite teal spinel originates from the historic Bitterfeld production in Germany, a source that is no longer active. Renowned for its captivating green fluorescence under outdoor light, this material glows beautifully when illuminated by sunlight. A truly unique and cherished gemstone.

We acquired this lot through an Indian broker in Jaipur who came across an old collection of miscellaneous synthetic materials. Its distinctive color and boule formation allowed us to identify the material immediately.
