Designer Nikos Koulis introduced his 77 collection in Paris in July 2026, blending precious diamonds with sustainable cellulose acetate. Interested buyers have since joined a waiting list to secure pieces from the debut range.
Why it matters
Koulis created this collection to evoke the spirit of the seventies while transforming common materials into fine jewelry. The move signals a broader luxury trend of elevating unconventional, plant-based substances through intricate craftsmanship.
The collection features cellulose acetate sourced from Germany, which is carved in Athens and finished in Italy. Koulis utilizes a proprietary concealed mechanism to set diamonds directly into the tortoiseshell-patterned material.

Culture Shift
The use of cellulose acetate in fine jewelry reflects a growing cultural movement where luxury designers prioritize sustainable materials alongside traditional gemstones. This trend challenges legacy beauty standards by elevating everyday synthetic components to the status of high-end accessories.
Prospective buyers should anticipate limited initial availability as the brand manages a growing waiting list for the new designs. The manual nature of the European production process ensures high quality but may influence the wait time for individual orders.
The takeaway
This collection demonstrates how designers can successfully blend retro influences with modern, sustainable manufacturing techniques. Readers interested in similar luxury trends should note that the value of such pieces often stems from the unique fusion of high-end stones and alternative base materials.
