Introduction
Every diamond is graded by the same four fundamentals: Cut, Colour, Clarity, and Carat — better known as the 4 Cs.
But what most buyers don’t realize is this:
Two diamonds with the same carat weight can look completely different, simply based on how the other three Cs are handled.
At Diamondboi, we don’t chase numbers — we chase presence, brilliance, and longevity.
Here’s how the 4 Cs actually work… and how we set our standard.
⸻
1. Cut — The Only C That Creates Sparkle
Cut is not the shape. It’s how well the diamond is proportioned and finished.
A perfectly cut diamond:
• Reflects light internally
• Returns maximum brilliance
• Appears larger and brighter than its carat weight
A poorly cut diamond, even if it’s colourless and high clarity, will look dull.
Our standard:
✔ Excellent Cut only
No shortcuts. No “Very Good.”
If it doesn’t sparkle under natural light, it doesn’t make the cut.
Cut is the difference between a diamond that looks expensive… and one that just weighs more.

2. Colour — Why We Stay in the D–E Range
Diamond colour is graded from D (colourless) down to Z (noticeable yellow or brown tones).
Most diamonds sold online fall into the G–J range, where warmth becomes visible — especially once set in white gold or platinum.
Our standard:
✔ D–E colour
Why?
• Icy white appearance
• Cleaner contrast with pavé and halos
• Better long-term satisfaction (and upgrade value)
Once a diamond is set, you can’t unsee warmth.

3. Clarity — Clean to the Eye Isn’t Always Clean Enough
Clarity measures internal inclusions and surface blemishes.
While many brands market “eye-clean” diamonds, that definition varies wildly.
✔ VVS2 or higher
This means:
• No visible inclusions
• No durability risks
• No clouds that affect brilliance
You’re not just buying how it looks today — you’re buying how it holds up over decades.

4. Carat — Size Is Only Impressive When Quality Is Right
Carat is weight, not visual size.
A poorly cut 3.00ct diamond can look smaller than a well-cut 2.50ct.
A warm stone can appear darker.
A cloudy stone can lose life.
At Diamondboi, we believe carat should enhance quality — not replace it.
That’s why we start with the first three Cs before talking size.

The Diamondboi Standard (In One Line)
D–E Colour · VVS2+ Clarity · Excellent Cut · Thoughtfully Balanced Carat
This is the baseline — not the upgrade.
It’s why our diamonds:
• Photograph brighter
• Perform better in all lighting
• Age beautifully
• Hold value within our lifetime upgrade program

Final Thought
Anyone can sell a diamond by weight.
Not everyone is willing to say no to inventory that doesn’t meet their standard.
After 20 years at the bench, this is ours.
If you’re choosing a diamond to last a lifetime,
the standard matters.
