Diamonds remain the foundation of fine jewellery across markets, but what drives their success today goes beyond the traditional 4Cs.
1. What Matters Most Today
- Brilliance & visual appeal matter more than technical perfection
- Buyers are increasingly open to flexible quality ranges if the design is strong
- Shape and proportion influence sellability as much as grading
2. Natural vs Lab-Grown
- Natural diamonds → Emotional value, legacy, higher price positioning
- Lab-grown diamonds → Accessibility, larger sizes, strong retail movement
Most retailers today benefit from carrying both, depending on customer segments.
3. Shapes That Consistently Perform
- Round → Highest demand, safest seller
- Oval → Modern + elongating, strong retail pull
- Emerald → Clean, premium appeal
- Pear / Marquise → Differentiation with character
4. Commercial Takeaway
- Focus on balanced quality, not just high grades
- Build variety across shapes and price points
- Prioritise design + presentation over specs alone
