*** ### Natural vs Lab-Grown Diamonds While lab-grown diamonds have increased their market share (now representing roughly 20% of global diamond supply), they are predominantly small stones under 3 carats and are produced in high volumes. In contrast, **large natural rough diamonds** (especially 5+ carats) remain relatively scarce and highly sought after by collectors and investors. Natural diamonds offer unique geological history, rarity, and long-term value appreciation that lab-grown stones typically cannot match. KimberLite deliberately focuses on these natural gem-grade rough diamonds to provide investors with authentic, scarce assets that have historically demonstrated strong price growth over time.
