Greenish Blue Beryl, Also Known as Paraiba Beryl
Typically, greenish-blue or bluish-green beryl is classified as aquamarine. However, this specific “neon intense greenish blue” hue is incredibly rare and is often compared to the striking color of Paraiba tourmaline, making it a standout among other beryls.
Beryl: An Overview
Beryl is a mineral composed of beryllium aluminum cyclosilicate, with the chemical formula Be3Al2(SiO3)6.
Varieties of Beryl
Well-known varieties of beryl include:
Crystal Structure and Colors
In nature, beryl crystals can reach substantial sizes, sometimes growing up to several meters in length. While terminated crystals are relatively rare, pure beryl itself is colorless, with its various colors resulting from trace impurities within the mineral structure.
Possible Colors of Beryl
The possible colors include:
- Green
- Blue
- Yellow
- Red (the rarest)
- White
In addition to being a beautiful gemstone, beryl also serves as an ore source of beryllium, a valuable element.
Hexagonal Crystal System
Beryl belongs to the hexagonal crystal system, generally forming as hexagonal columns. It may also occur in massive forms.
Cyclosilicate Structure
As a cyclosilicate, beryl incorporates rings of silicate tetrahedra arranged in columns along the C-axis, forming parallel layers that are perpendicular to the C-axis. This unique structure results in channels that run along the C-axis of the crystal.
Color Variations
These channels can accommodate various ions, neutral atoms, and molecules, disrupting the crystal’s overall charge and allowing further substitution at aluminum, silicon, and beryllium sites. Such changes in its internal structure contribute to the distinct color variations seen in different types of beryl.
The alkali content within the silicate ring channels also affects the refractive indices and birefringence, adding further diversity to beryl’s optical properties.
The Paraíba Color
The color of greenish blue beryl ranges from greenish blue to bluish green, green, blue, and even violet hues. Among these shades, the most coveted by collectors and gemstone enthusiasts are greenish blue and greenish violet, as they possess an intense vibrancy that draws immediate attention.
The striking resemblance of this unique color to the vivid tones of Paraiba tourmaline is a significant factor that contributes to its allure.
