The diamond buying guide
Buying a diamond need not be daunting. Learn the four qualities that define every stone, decide which matter most to you, and you can choose by preference rather than by guess. This is the short path through everything in our journal.
Begin with the four Cs
Cut
How well the stone is faceted — the C that most affects sparkle. Start here.
Read →Colour
From colourless D down the scale — or, in a fancy, the colour itself.
Read →Clarity
The tiny inclusions formed as the crystal grew, graded at 10×.
Read →Carat
Weight, not size — and why price climbs steeply as it rises.
Read →New to all four? Read the 4Cs overview first.
Then narrow it down
Ready when you are — every VHENY stone is certified, conflict-free and wholesale-priced.

Common questions
- How do I start buying a diamond?
- Begin with the four Cs — cut, colour, clarity and carat — and decide which matters most to you. Set a budget, then compare independently certified stones side by side before choosing.
- Which of the 4Cs matters most?
- For most buyers, cut — it drives the sparkle. Once the cut is strong, balance colour, clarity and carat to your taste and budget.
- Is it cheaper to buy a diamond in Antwerp?
- Generally yes. Buying at the source — the Antwerp diamond district — means wholesale pricing, without the retail mark-ups a stone collects on the way to a high-street window.
