A coloured stone tells a story that a diamond cannot. Each stone has its own distinctive hue and visual identity — your ring will be like no other. It is also a matter of meaning and individuality: choosing a sapphire, a tourmaline or a tsavorite means stepping beyond the expected and expressing a personal taste. It is the choice for those who want a ring that turns heads, yet could never be mistaken for anyone else's.

Each Color Blossom piece is built around a coloured centre stone, framed by a halo of diamonds. The collection draws from four stone families:

• Sapphires
• Tourmalines
• Spessartite garnets and Tsavorite
• Spinel

The collection ranges from €7,500 to €24,500, depending on three factors: the nature of the centre stone, its carat weight and the intensity of its colour. The price always includes the centre stone, the diamond halo, the 18-carat gold setting, the gemmological certificate, ring sizing and secure worldwide delivery.

Yes, without exception. Bonnot Paris is the only French jeweller to hold membership of the ICA (International Colored Gemstone Association). We do not sell synthetic stones. Every stone is sourced directly through our offices in Jaipur, Sri Lanka and Bangkok. All stones are delivered with a certificate issued by an independent gemmological laboratory (Bellerophon, ICA, GRS or LGL), attesting to their nature, origin and any treatments.

Two tried-and-tested methods. The simplest: discreetly borrow a ring she wears on her ring finger (or a similarly sized finger) and bring it to us. We take the exact measurement in a matter of minutes. The second: order a standard size (52–54 for France) or go slightly larger to ensure the proposal goes smoothly, then use our complimentary ring-sizing service afterwards. We are well accustomed to these discreet missions — do not hesitate to book an appointment to talk it through.

Each Color Blossom ring is handcrafted in workshops in France and Italy. Allow an average of 4 to 6 weeks: because the centre stone is generous in size, the setting requires more time than on the Mini Color Blossom. If you have a fixed date in mind — a proposal, a celebration, a trip — let us know from the very first exchange and we will adjust the schedule accordingly.

Yes, at several levels.

Standard: gold colour (yellow, white or rose), exact ring size, inner engraving (initials, a date, a short message).

Extended: change of centre stone, adjustment to the number of diamonds in the halo, modification of the setting — an expert will guide you through this by appointment.

Fully bespoke: we offer a dedicated service where the ring is designed entirely with you, around a rare stone selected for your project.

The design is identical — a floral silhouette, diamond halo and refined setting — but the centre stone differs in scale. The Color Blossom features a generous stone, while the Mini Color Blossom offers more delicate proportions. The choice comes down to your budget and the shape of the hand. Book an appointment to try both collections side by side.
