Clarity and Transparency

Gemstone Clarity and TransparencyLet’s clarify the terminology used to describe various levels of clarity and transparency. Clarity of colored gemstones ranges from transparent, semi- transparent to translucent, semi-translucent to opaque. On the other hand, transparency flaws can be described as crystal, milky, cloudy, and sleepy. These terms are mostly used to describe the basic natures and properties of a gemstone. While some stones are naturally opaque like opal, others are highly transparent and reflective like diamonds.
In addition, not all inclusions are considered to be negative; some of them may even enhance the beauty of the natural gemstone. For example corundum's usually come included with mineral crystals and silks. While crystals degrade eye appeal, silk like fibers of rutile enhance their overall beauty. When considering gemstones, make sure to keep their hardness composition in mind. False surfaces and fractures are inclusions that are a risk to its durability.
The beauty of a colored gemstone is that even after being cursed with blemished facets, the gemstone remains beautiful with deep colors. Inclusions are considered flaws effecting price and clarity, but they also tell us that a gemstone is natural. Inclusions are internal flaws that are natural blemishes consisting of external marks or abrasions. One cannot apply the factors mentioned to all gemstones equally because each gemstone’s family has their own characteristics. For example, rubies have more inclusions than sapphires even though they belong to same family of mineral (corundum). Some inclusions are seen with the naked eye, while others are more noticeable through microscopic tools.
External flaws of a gemstone include scratches, pits, abrasions and nicks. These are usually found on either facet or the griddle of a gemstone. External flaws are outside defects that are mainly caused due mishandling of stones. Some stones (I.e. Emerald and tanzanite) are fragile in nature, and therefore, should be handled with care.
