Introduction to Gemstones
Gemstones, often referred to as gems, are precious or semi-precious stones that are cut and polished for use in jewelry and other decorative forms. Beyond their aesthetic appeal, gemstones hold significant cultural, historical, and economic value. Ranging from diamonds and rubies to more obscure stones like tanzanite and tourmaline, each gemstone has its unique characteristics and story.
What is a Gemstone?
To understand what defines a gemstone, it’s essential to consider several key factors:
- Beauty: The visual appeal, including color, cut, and clarity.

- Durability: Resistance to scratching, breaking, or fading.
- Market Demand: The demand in the jewelry market affects a gemstone’s worth.
The Four Cs of Gemstones
When evaluating gemstones, particularly diamonds, the Four Cs are crucial:
- Cut: This refers to how well a gemstone has been shaped and faceted. A well-cut stone reflects light beautifully.

- Clarity: This pertains to the presence of internal or external flaws, known as inclusions and blemishes.
