One evening, my friend Hasan and I were sipping tea at a local Dhaka tea stall. He showed me a photo of a jaw-dropping diamond.
“Imagine owning a 100-carat diamond,” he said, eyes wide with wonder.
I smiled. “That’s huge! But do you know how much it’s worth?”
He leaned in closer. “Tell me!”
And that’s how our fascinating dive into 100-carat diamonds began.
Understanding Carats: What Does 100 Carats Mean?
Before we talk about price, let’s break it down:
- 1 carat = 200 milligrams (0.2 grams).
- 100 carats = 20 grams.
In short, a 100-carat diamond is enormous. It’s extremely rare, making it one of the most sought-after treasures in the world.
For context, smaller diamonds like a 1-carat diamond weigh less than a paperclip and still shine brilliantly. Curious about 1-carat prices? Check out our guide on how much a 1-carat diamond ring costs.
The 4 Cs: Factors That Determine Diamond Value
The price of a diamond depends on the 4 Cs:
1. Carat (Weight)
Larger diamonds are rare, so prices multiply, not add. A big diamond like 100 carats is worth millions.
2. Cut
The cut determines how well the diamond sparkles. A perfect cut enhances its brilliance, increasing the value.
3. Color
Colorless diamonds (graded D) are the most expensive. Slight yellow tints reduce their price.
4. Clarity
Fewer flaws (or inclusions) mean a higher price. Diamonds graded Flawless (FL) are extremely valuable.

- Per carat: $200,000 to $300,000 (or more).
