2. The 4 C’s of Diamond Quality — Always the Standard
Both natural and lab grown diamonds are graded by the 4 Cs: Cut, Color, Clarity, and Carat. Here's what really matters:
-
Cut = how it sparkles
→ We only use Excellent or Very Good. It’s the most important C, as it is not nature's given characteristic, but a polisher's expertise and craftsmanship.
-
Color = how white it looks
→ We love the D–G range for its crisp, bright white look. While D–E diamonds are often chosen for investment, F–G diamonds offer the best balance of beauty and value—yellow tones are virtually invisible unless directly compared to D–E, so there’s no need to worry. When the design calls for it, warmer tones can be stunning too—these are often referred to as champagne, cognac, or even brown diamonds, and they bring character and a distinctive richness to the piece.
-
Clarity = how clean it looks
→ We pick eye-clean diamonds. IF–VVS stand for no or almost no inclusions and are mostly chosen for investment; VS and SI1 are optimized for everyday wear. If you can’t see inclusions, they won’t matter.
-
Carat = size and weight
→ Bigger isn’t always better. Let’s find your perfect proportion.
3. Choosing Your Diamond, Made Simple
| Your Style |
Natural Diamond Tips |
Lab Grown Diamond Tips |
| Heirloom / Investment |
D–E color, IF–VVS clarity, Excellent cut, GIA or HRD cert |
D–F color, VS+ clarity, Excellent cut, GIA or IGI cert |
| Daily Wear / Modern Piece |
F–G color, VS2–SI1 clarity, Excellent/Very Good cut |
Choose what shines brightest to your eye—cut is key, clarity and color shifts cost less |
💡 Fun fact: With lab grown, a clarity upgrade (e.g. VS to VVS) may only cost 5% more. In naturals, that could be 20% or more!

6. Fast FAQs
Will a lab-grown diamond keep its value?
Buy for love, not resale. Tech evolves fast—brilliance, responsibility and ethics are the real return.
Are natural diamonds always ethical?
Only when documented. We rely on trusted sources like GIA, SCS 007, and the Kimberley Process.
What matters more—cut or carat?
Always cut. A well-cut diamond will sparkle more than a larger one with poor cut.
