Despite economic fluctuations in 2025, natural diamonds remained a dominant force in the luxury market, driven by a growing consumer preference for rarity and long-term value. This period saw a notable shift toward larger center stones and elongated fancy cuts, reflecting a broader trend of using jewelry as a medium for personal storytelling. Driven largely by younger generations, the market prioritized high-clarity stones and ethical transparency, ultimately reinforcing the natural diamond's status as a unique, authentic alternative to mass-produced options.
