Ans: Lab-grown emerald has the same chemistry, scratch resistance, and color as natural emerald, but grown in a lab instead of the earth. Not to be confused with emerald simulants, which are things meant to look like an emerald.
Ques: Is a Lab-Grown Emerald a Real Emerald?
Ans: A lab-grown emerald is a real emerald but not a natural emerald. The methods used to create them in labs require expensive equipment. The process is slow and energy intensive, and the yield of facetable material is low.
Ques: Why are there inclusions (resembling hairline cracks) on the Emerald?
Ans: Unlike diamonds, where clarity plays a significant role in valuing a stone, inclusions are to be expected in emeralds. Indeed, they can be found in 99% of natural emeralds so if you find a stone without, chances are it’s synthetic. The inclusions are formed of gases, other minerals and crystals, and liquids that emeralds take on during the crystallisation process and are often viewed as desirable features. Known as ‘jardin’ (French for garden) in the trade, they can create attractive patterns, making no two stones the same, which actually increases the value of the gem. Emerald clarity refers to what the stone looks like on the inside and is usually assessed with the naked eye, rather than under magnification. Due to their inherent inclusions, emeralds are often treated with oils or resins to enhance their clarity and improve their quality and grade.
