Founder and creative director Valérie Messika showcases the region’s defining landscapes with vivid green, blue, yellow and crimson centrepiece gemsMessika’s latest haute joaillerie collection marks a compelling evolution for a maison that built its reputation on the brilliance of diamonds. With Terres de Contrastes, founder and creative director Valérie Messika looks beyond the stone itself, embracing the rich palette of Botswana – a country where extraordinary diamonds emerge from landscapes defined by striking natural contrasts.Le Okavango Blue diamond from Botswana.

Vivid gemstones converse with diamonds in a collection inspired by Botswana’s three defining landscapes: the lush Okavango Delta, the fiery Kalahari Desert and the dreamlike Makgadikgadi salt pans.Le Okavango Blue diamond is the largest of its kind ever found in Botswana. Photo: HandoutThe collection’s undisputed show-stopper is Le Okavango Blue, centred around one of the most exceptional diamonds ever unearthed in Botswana. Discovered at the Orapa mine in 2018 as a 41.11-carat rough, the stone was polished into an extraordinary 20.46-carat fancy deep blue diamond – the largest of its kind ever found in the country. More than 500 smaller diamonds cascade around the neck in fluid lines that mirror the delta’s winding waterways, allowing the mesmerising blue diamond to command every glance. It is a jewel that speaks of geological rarity as well as artistic restraint.Le Okavango Blue was discovered in the Orapa mine.

Féroce captures the silent menace of the crocodile with sculptural gold, pavé diamonds and a hypnotic 16.98-carat Australian black opal whose flashes of electric blue and emerald green evoke water in perpetual motion. In Règne, the powerful silhouette of the Kalahari’s big cats is abstracted into sleek gold architecture punctuated by custom-cut onyx and anchored by a warm Fancy Deep Brownish Yellow diamond that echoes the desert’s sun-baked terrain.The Féroce necklace from Messika’s high jewellery collection, Terres de Contrastes.

Five serpentine rows of marquise-cut diamonds drape across the collarbone before revealing a vivid 13.54-carat rubellite, its saturated crimson-pink hue recalling the fleeting colours of sunset across the Makgadikgadi salt pans.
