Description from the seller
Beautiful untreated specimen from swat available
Weight. 106 grams
Untreated piece
Origin swat Pakistan
* Color: Rich green to bluish-green. The deeper, more vivid green the color, the more valuable the emerald is.
* Hardness: 7.5–8 on the Mohs hardness scale, making it suitable for jewelry, though it can still chip because of internal fractures.
* Luster: Vitreous (glass-like) shine when polished.
* Clarity: Most natural emeralds contain visible inclusions (called “jardin,” French for “garden”). These inclusions are considered a natural feature rather than a flaw.
* Transparency: Transparent to translucent.
* Crystal System: Hexagonal.
* Chemical Composition: Be₃Al₂(Si₆O₁₈) (beryl colored green mainly by chromium and/or vanadium).
* Specific Gravity: Approximately 2.67–2.78.
* Refractive Index: About 1.57–1.58.
Quick identification
Green to bluish-green color
Usually contains natural inclusions (“jardin”)
Glass-like luster
Hardness of 7.5–8
Hexagonal crystal structure
These characteristics help distinguish natural emeralds from many green gemstones, though laboratory testing is often needed to separate them from synthetic emeralds or look-alikes.
