Difference between Colombia and Zambia emerald

According to Unity, the May birthstone “Emerald” is one of the most delicate and valuable types of gemstones in the world. Among them, the top-quality Emeralds from Colombia and Zambia have some unique differences that we’d like to highlight:

✅ Color:

• Colombian Emeralds typically have a vibrant, rich green color with a slightly bluish tone that is truly captivating.

• Zambian Emeralds often show a deeper green hue with a stronger bluish overtone compared to Colombian ones.

✅ Clarity:

• Colombian Emeralds usually contain inclusions known as “jardin” (French for “garden”)—a hallmark of natural emeralds.

• Zambian Emeralds tend to have fewer inclusions than Colombian ones, and a notable type of inclusion called “2-phase” is commonly seen, serving as a signature feature.

✅ Origin:

• Colombian Emeralds come from three major mines in Colombia: Muzo, Chivor, and Coscuez.

• The main source of Zambian Emeralds is the Kagem Mine, which is one of the largest emerald mines in the world.

✅ Trace Elements:

• The green color in emeralds is primarily caused by chromium and vanadium.

• Compared to Zambian emeralds, Colombian emeralds generally contain less iron. This is why Zambian emeralds often appear to have a darker or deeper tone.

✅ Market Value:

• Due to their color quality and rarity, Colombian emeralds remain the most valuable in the market.

• However, for those looking for a more affordable option without compromising too much on beauty, Zambian emeralds are an excellent choice.
