Aquamarine Stone Quality
Aquamarine is valued and admired for its vibrant greenish-blue to blue hue, outstanding vitreous luster, brilliance, and elegance. Certain parameters determine the quality of this gemstone and based on these parameters, the Aquamarine value, quality, and authenticity can be evaluated. The parameters include:
Origin
: Aquamarine mines have been discovered in Brazil, Sri Lanka, Mozambique, Nigeria, Zambia, USA, Madagascar, India, and Burma. Brazil’s Santa Maria Aquamarine gemstone sourced from the popular Santa Maria de Itabira mine is considered the most sought-after variety with exceptional and loupe-clean clarity. The Aquamarine crystals resourced from the mines of Mozambique (called Santa Maria Africana Aquamarine) and Brazil (called Espirito Aquamarine) are other popular origin varieties found in the finest color and clarity. Sri Lankan Aquamarine holds a fair reputation in the gem industry because of its high transparency.
Color
: The trace amounts of ferrous iron in Aquamarine raw give the brilliant blue color to crystal. Aquamarine colour range can be blue to deep blue, very slightly to dark greenish-blue with very light to moderately strong color intensity and tone. The purer, intense, deep and bright blue Aquamarine is always more valuable than pale and dull ones. The presence of yellow, green, or brown tint degrades the quality of the gemstone and decreases the price as well.
Clarity
: Aquamarine, a Type I gemstone has splendid clarity standards and is a highly transparent blue-colored gemstone. It is known to have minor transparent inclusions. If inclusions are more, then it will hamper the transparency, luster and lower the quality of the gemstone. Some specimens of this gemstone contain ‘snow stars’ and display irregularly-shaped liquid droplets in a star formation.
Cut
: Cut and shape influence the overall value of Aquamarine gemstone. It is commonly found in oval shape but can be cut into a variety of fancy shapes including cushion cut, trillion cut, rectangular, and emerald cut. An excellent cut and perfect symmetry enhance the color and luster of this alluring gemstone. A highly faceted Aquamarine is more expensive than oval or round-shaped Aquamarine due to the stone wastage involved in the cutting process.
Carat Weight
: Unlike other factors, gem-quality and fine raw Aquamarine can easily come in sizes from very small to very large. The superior quality Aquamarine even in the small size demands a decent value. Aquamarine stone price per carat gradually decreases for gemstones above 25 carats as it is difficult to use them in jewelry.
