Engagement rings

For a long time the classic engagement ring has been the solitary diamond, alone on its setting, in the spotlight. Even though fashion changes, it remains an iconic piece of jewelry and a symbol of love. Why is this so? Because in the 1950s, the world’s largest diamond company, De Beers, invented a slogan that would become a milestone: “A diamond is forever”. A diamond is forever. Like a marriage. With these four words, De Beers met with incredible success and in 4 years increased its diamond sales by 55%.

But today nothing prevents the bride or groom from choosing a ring with a colored stone. Engagement rings can include rubies, sapphires, emeralds, aquamarines, amethysts or topaz. The settings can be in white gold, yellow gold, can include one or more stones. Let’s break free from the codes. Here is our selection of engagement rings from Maison Mohs
