Geological Formation and Sources
Aquamarine is a variety of beryl, a mineral composed of beryllium aluminum silicate with the chemical formula Be₃Al₂(SiO₃)₆. Its distinctive blue color results from trace amounts of iron impurities within the crystal lattice. This gemstone forms in pegmatites—coarse-grained igneous rocks—where conditions allow for the growth of large, well-formed crystals. The presence of iron during crystallization determines the intensity and shade of the blue hue, with deeper colors often indicating higher iron content and greater value.
The primary sources of high-quality aquamarine are concentrated in specific regions known for their pegmatite deposits. According to the provided sources, major mining locations include Pakistan, Mozambique, Brazil, Zambia, Nigeria, and Madagascar. These countries are renowned for producing aquamarine with exceptional color and clarity, catering to the global demand for fine jewelry. Brazil, in particular, has historically been a significant producer, yielding large, transparent crystals that are often faceted for gemstone markets. The geographic distribution of aquamarine sources highlights the global nature of its trade, with each region contributing unique characteristics to the gem’s overall availability and quality.
Gemological Properties
Aquamarine is prized for its durability and visual appeal, making it suitable for a wide range of jewelry applications. Its key gemological properties are as follows:
- Color: Ranges from light blue to deep blue, and sometimes blue-green. The most valued shades are a medium to deep blue, reminiscent of the ocean. The color is consistently attributed to iron impurities.
