Bagues de fiançailles

At Deloison Paris, every engagement ring is designed, crafted and set by our own jewellers in our Paris workshop. This in-house expertise, rare for a jewellery house of our size, allows us to oversee each piece from the initial model to the final polish. Born from a family passion, the Maison combines the exacting standards of high jewellery with a contemporary, refined aesthetic.

Made to order, with no ready-made stock, our creations are offered at a fair price throughout the year, with no discounts or seasonal sales.

Finding a women’s engagement ring that reflects her personality

The right piece reflects the person who will wear it. For a classic style, a solitaire engagement ring with clean lines remains timeless. A romantic spirit will be drawn to a halo of brilliant-cut diamonds, as featured in our halo engagement rings. A trilogy ring or an asymmetric setting expresses a bolder personality. Take inspiration from her jewellery, too: someone who loves the warm tones of gold will appreciate a yellow gold engagement ring.

What determines a gemstone’s quality?

Four criteria, known as the 4Cs, are used to assess a diamond: carat weight, colour, clarity and cut, which determines its brilliance. The diamonds in our diamond engagement rings are certified by recognised gemmological laboratories. The setting is equally important: the claws, the height of the setting and the width of the band determine comfort and how well the ring will sit alongside a future wedding band.

Bespoke jewellery: from an idea to a unique piece

Because we craft our jewellery in our own workshop, every detail can be tailored: the gold colour, the shape of the centre stone and the setting. Green sapphire rings, blue sapphire rings and emerald rings bring a touch of colour, while engraving inside the band is complimentary. Do you have a specific idea for your proposal? Our gemmologists will transform it into a unique piece.

18-carat gold and symbolism: jewellery made to last

We work exclusively with 18-carat gold, with a fineness of 750, combining lustre and durability. Cleaning with warm water and mild soap is sufficient for routine care, while having the claws checked in our workshop helps keep the stone secure. Inherited from ancient Rome, tradition places the ring on the left ring finger, once believed to be connected to the heart. The diamond symbolises an unbreakable love, the sapphire fidelity and the emerald hope.

An engagement ring is given at the proposal and showcases a centre stone. A wedding band, generally more understated, is exchanged on the wedding day. Both can be worn together on the left ring finger, with the wedding band closest to the heart.

A solitaire showcases a single centre stone. A halo ring surrounds it with brilliant-cut diamonds; a pavé solitaire features small gemstones set into the band; and a solitaire with side stones adds gemstones on either side of the centre stone.

Borrow a ring she wears on her ring finger and bring it to the boutique to have it measured. Resizing is possible after the proposal.

As our creations are made to order, we do not accept returns or exchanges unless agreed in writing beforehand. We therefore recommend trying on our designs in the boutique before placing your order. For more information, please visit our Delivery and Returns page.
