JCK key take points;
1. Natural diamonds are being pushed back into the spotlight
JCK’s 2026 show coverage says the natural versus lab-grown conversation is still a major topic, but the interesting part is the shift in language: as lab grows the mass market, demand for natural diamonds in meaningful sizes and distinctive cuts is becoming stronger. That’s your angle: lab diamonds expanded the market, but they also made natural diamonds feel more intentional.
2. Distinctive cuts are winning
Elongated shapes are still hot. Ovals, pears, marquise, emerald cuts and other non-round shapes are being used as markers of originality. Rounds are still dominant, but customers are clearly looking for shapes that feel different and photograph well.
3. Bigger natural center stones are still moving
JCK cited NDC data showing demand grew for the 2.00 to 2.24 ct range in 2024, while the classic 1.00 to 1.04 ct range lost share. That means buyers are still stretching upward when the stone feels worth it.
4. Warm natural diamonds are becoming a story
De Beers’ “Desert Diamonds” campaign is pushing warmer natural tones like champagne, amber, sunlit whites and whiskey colors. That matters because it gives retailers a new way to sell natural diamonds beyond the old D color obsession.
5. Lab-grown diamond grading is being separated from natural language
GIA’s 2025 update is huge for your content. GIA said it will no longer use the natural-diamond grading language for lab-grown diamonds, because lab diamonds are manufactured products and usually fall into a narrow color and clarity range. Instead, they’ll be assessed as “premium” or “standard.” That is a strong narrative point.
