MAXINE (Beryl)
Maxixe Beryl: Deep Blue Color, Light Sensitivity & Identification
Maxixe beryl is a rare deep-blue to blue-violet variety of beryl historically associated with material from Brazil. Its color can be caused by radiation-related color centers and may fade with light or heat. The name is sometimes misspelled “Maxine” in older labels; verify specimen documentation before changing a label.

Origin and Formation
Maxixe beryl was described from a locality in Brazil and is unusual because its blue color may be unstable. Beryl itself forms in pegmatites and hydrothermal environments; the distinctive color relates to defects and color centers rather than simply the chromium or iron mechanisms found in other beryl varieties.
Appearance and Properties
Beryl has a hexagonal crystal system and Mohs hardness around 7.5–8. Maxixe-type material is known for intense blue or violet-blue color that can fade. The term should be used carefully because not all blue beryl has the same color mechanism or stability.
Identification and Collecting
A gem laboratory can distinguish beryl and investigate color origin and stability. Do not identify Maxixe beryl solely by blue color. Retain any old labels, purchase records, and lab reports, especially if the specimen is historically significant.
Care and Handling
Keep Maxixe-type beryl away from prolonged bright light, strong heat, and harsh chemicals. Store in a closed, dark container when not on display and ask a gemologist before cleaning or exposing it to intense light.
Frequently Asked Questions
Is this material a natural mineral?
Origin varies by material. Some are natural minerals or biological products, while most jewelry moissanite is laboratory-grown. Accurate labeling and documentation are important.
Can appearance alone establish authenticity?
No. Expert examination and reliable provenance may be needed, especially for rare materials and trade names.
