"Helsinki" engagement ring, lab grown diamonds, ethical designer jewellery, STEPHANIE VAN ZWAM, made Switzerland

The Helsinki ring reflects the Finnish twilight, called “the blue moment”. This takes place shortly after sunset, when the landscape is tinted in an ethereal blue. It is more intense in winter when the blue light rises out of the snow, and because of the reflections from the snow, everything turns blue. The Finns call this phenomenon “sininen hetki”, it can also mean moments of peace and tranquility, particularly those that might occur in this magical space of time. Who will you share your “blue moments” with?
