Learn why diamonds priced at “magic numbers” like 1.00 ct or 2.00 ct cost much more. Discover how buying just under these weights (like 0.95 ct) can save you thousands without any visible size difference.
Why Carat “Magic Numbers” Cost You More
Diamond prices jump at certain weights.
These are called “magic numbers.”
The big jumps happen at:
- 0.90 → 1.00 carat
- 1.90 → 2.00 carat
At these points, price per carat increases sharply.
But the diamond itself doesn’t look much bigger to the naked eye.
Example: 0.95 vs 1.00 Carat
A well-cut 0.95 ct diamond can look nearly identical in size to a 1.00 ct diamond.
But the price difference is huge.
- 1.00 ct may cost 15–25% more than 0.95 ct
- Yet the face-up size is almost the same
If you place them side by side, most people won’t notice a difference.
Why Buyers Overpay
You may feel drawn to “a full carat.”
It sounds complete and impressive.
But sellers know this psychology.
That’s why they price these magic numbers at a premium.
Ask yourself:
Do you want to pay thousands more for a number on paper, or do you want value for your money?
How to Shop Smart
- Look just below the jump points (0.95 ct, 1.80 ct, 2.90 ct)
- Focus on cut quality, not just carat weight
- Compare face-up size, not the report number
- Use your budget to upgrade color or clarity instead
The Takeaway
When buying diamonds, numbers can mislead you.
A 0.95 ct well-cut diamond may look as good as a 1.00 ct.
Yet it saves you a fortune.
Don’t let “magic numbers” drain your wallet.
Shop smart, not symbolic.
