Find the Perfect Commitment Alliance

We offer you the option to choose between various types of engagement rings. You can opt for a beautiful half alliance with diamonds. A ring that is easy to combine with other styles and that stands out for being covered in its half by a row of diamonds subject to garnet or channel. You can also choose a half alliance with baguettes made in white gold or 18kt yellow gold. How would you like to surprise your partner with a diamond alliance? In Nicols we make your dreams come true. No matter the engagement ring you dreamed of. Our 3D jewelry design department is ready to customize your handmade alliance thanks to the latest technologies. This process allows us to show you the final result before even manufacturing your 100% custom ring in just one week.
