GERMSTONES AMYTHYST TRADE
The writeup connotes how rough Amethyst Gemstone will be trading from African mines on CIF or FOB to international trading system, depending on what both parties agree. The Mineral is usually used by jewelers after being refined.
When it comes to raw amethyst from African mines, determining the "absolute best" quality becomes even more subjective due to the lack of cutting and polishing that reveals the final gemstone's characteristics. However, here's what's generally considered high-quality rough amethyst from Africa:
Color:
•Deep reddish-purple to vibrant purple: This is the most sought-after color, with strong saturation and minimal color zoning (variations in color within the stone).
•Eye-clean: Ideally, the amethyst should be free of visible inclusions (flaws) to the naked eye.

Origin:
While amethyst deposits exist in various African countries, some regions are known for their exceptional quality:
Nigeria:
Color: Primarily known for deeper reddish-purple hues compared to amethysts from other African regions. This is due to a higher iron content.
Clarity: Generally, moderately included with visible fractures and imperfections. Finding eye-clean (flawless to the naked eye) amethyst from Nigeria is uncommon.
Crystal Formation: Crystals can range from well-formed to relatively blocky and can be smaller in size compared to amethysts from other African sources.
Zambia: Renowned for deep, vibrant purple amethysts with excellent clarity.
Namibia: Produces amethysts with a strong reddish hue and good transparency.
Madagascar: Offers a range of amethyst colors, including lavender and even rare green amethyst.
For deep, reddish-purple hues: Nigerian amethyst is preferable
Cutting and Clarity:
Expertly cut: The amethyst is cut to maximize its brilliance and fire (play of light within the gemstone)
High clarity: Ideally, the amethyst has minimal internal flaws that might affect its transparency and beauty.
