Gemstone Clarity Explained: VVS, VS, SI & More
When shopping for a natural gemstone, you'll often come across terms like VVS, VS, SI, Eye Clean, and Included. Understanding these clarity grades is essential because clarity directly impacts a gemstone's beauty, rarity, and value.
In this comprehensive guide, we'll explain gemstone clarity grades in simple language, helping you choose the right gemstone whether you're buying a loose stone for investment or creating custom jewelry.
What Is Gemstone Clarity?
Gemstone clarity refers to the number, size, and visibility of natural imperfections inside or on the surface of a gemstone. These imperfections are known as inclusions and blemishes.
A gemstone with fewer visible inclusions usually appears brighter, more transparent, and more valuable.
Unlike diamonds, every gemstone species has different clarity expectations. For example, emeralds naturally contain more inclusions, while peridot and tourmaline often exhibit excellent transparency.
Why Gemstone Clarity Matters
Clarity affects several important factors:
- Overall beauty
- Light reflection
- Brilliance
- Durability
- Collector value
- Market price
The cleaner the gemstone, the rarer it generally becomes.
