The brand’s logo in the center of each bottle is embedded with a single diamond. “As I come from Antwerp, the world’s diamond capital, I was inspired to integrate a certified diamond into the packaging design,” Mertens tells Luxe Packaging Insight. Each bottle comes with a certificate issued by HRD Antwerp to ensure the stone’s authenticity.

Cuvée Karma is a dosage zero Champagne – meaning it contains less than 3 grams of sugar per liter – and blends Chardonnay, Pinot Noir and Pinot Meunier. The bottle is topped with a cork stopper (Prioux) and a rose gold capsule (Vipalux).

It comes in a cardboard coffret (Full Pack) from the stock Luxe line, personalized with copper hot-stamping and a custom-made sleeve. A limited-edition, just 1,000 Karma bottles were produced, priced at €549. Also don’t forget to check our list of the most expensive bottles of wine in the world.
