💎 What Makes a Gem So Expensive?

You might be wondering: why do some gems sell for millions while others cost just a few hundred dollars? Great question.

Here are the key factors that influence a gem’s value:

🔍 1. Rarity

The rarer the gem, the higher the price. Some gemstones form under particular geological conditions and are found in only one location on Earth.

✨ 2. Color and Clarity

Especially for diamonds and colored stones, color saturation and the absence of visible inclusions play a significant role.

💎 3. Carat Weight

Size does matter—but only when combined with other quality factors.

🛠️ 4. Cut Quality

A masterfully cut gem maximizes brilliance, sparkle, and visual appeal.

🌍 5. Origin

Gems with known and prestigious origins (like Kashmir sapphires or Burmese rubies) often carry higher value.
