The difference between precious and semi-precious stones

The classification of gemstones into precious and semi-precious categories is an age-old practice that dates back to ancient times. However, in modern times, this classification has been questioned and debated within the gem industry. Here are some key differences between precious and semi-precious stones:


1. Historical Perception:

Historically, gemstones like diamonds, rubies, emeralds, and sapphires were considered precious due to their rarity, historical significance, and high demand. All other gemstones were grouped under the semi-precious category. This classification was based on tradition and cultural perceptions.

2. Value and Rarity:

Precious gemstones are typically rarer and more valuable than semi-precious stones. They are often associated with luxury, wealth, and high societal status. However, the value of a gemstone is determined by factors like rarity, color, clarity, and size, rather than its classification as precious or semi-precious.

3. Gemstone Types:

Some examples of precious gemstones include diamonds, rubies, emeralds, and sapphires. Semi-precious gemstones encompass a wide range of stones, including amethyst, citrine, garnet, peridot, and turquoise, among others.

The distinction has been reevaluated in modern times, encouraging a focus on the beauty and desirability of each gemstone, regardless of its classification.
