A 17 carat diamond ring lives in a world of its own — a world defined by rarity, luxury, artistry, and presence.
At this scale, a diamond is more than a gemstone.
It becomes an experience — a statement that captures attention, emotion, and the unmistakable allure of high-carat jewelry.
But how much does a 17 carat diamond ring actually cost? And what determines its value?
Let’s explore the real factors that shape the price of such a remarkable piece — and how Acredo transforms extraordinary diamonds into handcrafted, ethically sourced, one-of-a-kind designs.
Understanding the Value: What Does a 17 Carat Diamond Ring Cost?
The cost of a 17 carat diamond ring varies dramatically, depending on quality.
Here’s the quick answer:
A genuine, natural 17 carat diamond ring typically ranges from
$850,000 to well over $4,000,000+
Why the wide range?
Because at 17 carats, every detail of the diamond greatly influences price — color, clarity, cut quality, and origin.
For customers looking for a direct answer:
A 17 carat diamond ring usually costs between $850,000 and $4 million or more, depending on quality factors such as color, clarity, cut, and ethical sourcing standards.
What Makes a 17 Carat Diamond So Expensive?
A diamond this size is exceptionally rare.
To understand why, imagine searching through thousands of rough stones before finding a single piece large enough, clean enough, and strong enough to be cut into a 17 carat gem.
This scarcity is the starting point — but not the whole story.
Below are the factors that shape value, explained with clarity:
1. Color Quality (D–J Range Matters More Here)
At larger sizes, even subtle color becomes visible.
A D-color 17 carat diamond can be exponentially more expensive than an H-color one.
2. Clarity (Every Inclusion Matters)
The higher the clarity — especially IF or VVS — the higher the price climbs.
At 17 carats, clarity defines both beauty and structural integrity.
3. Cut Quality (Light Return Is Everything)
Even a diamond this size must sparkle.
A masterfully cut 17 carat diamond can appear larger, brighter, and more captivating.
4. Shape (Some Shapes Increase Value)
Emerald-cut, oval, and cushion diamonds in this size category are especially prized.
5. Ethical Sourcing & Certification
Acredo exclusively partners with Responsible Jewellery Council–certified suppliers, ensuring that every diamond — even rare high-carat stones — meets strict standards of responsible, traceable, and sustainable sourcing.

Why Custom Design Matters at This Level
A 17 carat diamond is extraordinary — which means the setting must rise to its level.
At Acredo, the design process ensures balance, security, and harmony, so the diamond is displayed with elegance and strength.

-
Sleek, modern solitaires
-
Art Deco–inspired geometric halos
-
Sculptural, handcrafted metalwork
-
Dual-band or custom split-shank silhouettes
-
Hand-engraved details unique to your story

Hand-polishing to achieve mirror-smooth surfaces
-
Secure structural planning for long-term wear

Bespoke engraving and finishing
These steps ensure both beauty and longevity — essential qualities for a ring carrying a stone of this size and significance.
