In the introduction to emeralds, it’s important to note that emeralds are a specifically colored green variety of the mineral species beryl, with the chemical formula Be3Al2Si6O18. This species also includes many other varieties. The characteristic green color of emeralds is due to trace amounts of chromium or vanadium. There are several types of emeralds, each with unique features and origins.
Brazilian Emerald: These emeralds are generally yellowish-green and are known for their clarity. They show a less deep green compared to their Colombian counterparts but are renowned for their clarity due to their lighter tone, allowing more light into the stone.
Zambian Emerald: Emeralds from Zambia are typically bluish-green and cooler and darker in tone than Colombian and Brazilian emeralds. They may contain certain inclusions, like flakes of minerals, but are desired for their unique ‘moody’ appearance.
Colombian Emerald: Colombian emeralds are highly sought after and typically have a warm emerald hue, balancing between bluish and yellowish green. They are known for having fewer fractures and inclusions and are often considered the rarest and most valuable.
Cat’s Eye Emerald: This variety shows a unique optical effect called ‘chatoyancy’, which appears as a glowing line through the stone. It is caused by aligned inclusions and can be found in emeralds from various global deposits.
Lab-Grown Emerald: Created in laboratories, these emeralds are chemically and optically identical to natural emeralds. They are formulated to be equivalent in hue, saturation, and purity as Colombian emeralds but are more accessible in terms of price.
Natural emeralds are those that formed through geological processes in the earth, and most on the market are treated to enhance clarity, typically using oil or resin. These treatments are standard practice and widely accepted in the industry.
The value and appeal of different types of emeralds vary based on their origin, color, clarity, and other factors. Colombian emeralds, for instance, are often the most prized for their unique color and clarity, while Zambian and Brazilian emeralds have their distinct qualities that make them desirable in different ways
