Understanding Gemstones

What Are Gemstones?

Gemstones are precious or semi-precious stones that are valued for their beauty and rarity. They are typically cut and polished to be used in jewelry and ornaments. Gemstones are classified based on their physical properties, such as hardness, refractive index, color, and brilliance.

Types of Gemstones

Gemstones can be classified into two main categories:

• Precious Gemstones: These include diamonds, rubies, sapphires, and emeralds, known for their exceptional quality and value.
• Semi-Precious Gemstones: This category includes a variety of stones such as amethyst, garnet, opal, and topaz, which are more abundant and generally less expensive.

Gemstone Properties

Various properties determine the quality and desirability of gemstones, including:

• Color: The hue of a gemstone is one of its most important features, influenced by its chemical composition.
• Clarity: This refers to the presence of inclusions or imperfections in the stone. Higher clarity typically increases a gemstone's value.
• Cut: The way a gemstone is cut affects its brilliance and how it reflects light. Well-cut stones radiate more sparkle.
• Carat Weight: The weight of a gemstone affects its value; larger stones are usually rarer and more expensive.
• Hardness: Measured by the Mohs scale, this property indicates how resistant a gemstone is to scratching and wear.
