Diamonds rings

The diamond rings par excellence are the engagement rings. The famous solitaire, the timeless American wedding ring: the diamond is the stone of marriage. Even if today things are changing and you can also offer a colored stone to your bride, the diamond remains the symbol of love. Why is that? Because in the 50’s the biggest diamond company in the world, De Beers, invented a slogan that will remain in the annals: “A diamond is forever”. A diamond is forever. A diamond is like a marriage, forever. With these four words, De Beers met with incredible success and in 4 years it increased its diamond sales by 55%.

Today, diamond rings have entered many homes. Not only in the form of an engagement ring, but in every type of ring that can exist. Here is Maison Mohs selection.
