BLUE SAPPHIRE ENGAGEMENT RINGS

The blue of the sapphire is universally associated with nobility of feeling and strength of commitment.
It embodies trust, faithfulness and serenity — values that make it the ideal stone to symbolise a shared promise for life.

But beyond its symbolism, the blue sapphire captivates with its singular brilliance.
Its colour — at once deep and luminous — has no equal among other precious stones.
It is a stone of character, lending every ring a strong, instantly recognisable style.

The blue sapphire offers an exceptional range of hues, from the palest blue to the most intense.
Each shade tells its own story — an emotion, a temperament, a style.

• Pastel Blue: delicate and luminous, for a ring of quiet refinement.
• Ceylon Blue: vivid, slightly light, emblematic of Sri Lanka.
• Cornflower Blue: velvety and elegant, with understated sophistication.
• Royal Blue: deep and intense, the benchmark of fine jewellery tradition.
• Peacock Blue: subtle green undertones, for a more singular creation.
• Kashmir Blue: a mythical and extraordinarily rare hue, with an incomparable velvety quality.

Hue directly influences a sapphire's value: the most saturated, luminous and well-balanced shades are invariably the most sought after.

The teal sapphire is a superb alternative to the traditional blue sapphire. Its blue-green tone — at once subtle and distinctive — makes it a truly unique stone.

The padparadscha sapphire, meanwhile, is one of the rarest and most coveted of all. Its delicate hue, blending pink and orange, evokes the colour of a sunset or a lotus blossom — from which it takes its name. A stone of exception, it appeals to those in search of originality and refinement.

The finest blue sapphires come from a handful of storied sources:

• Sri Lanka (Ceylon): light to medium blues, exceptionally luminous.
• Madagascar: a wide range of tones, from pastel blue to Peacock blue.
• Burma (Mogok): dense, richly saturated blues.
• Kashmir: a historic deposit now exhausted, whose stones rank among the rarest in the world.

Each origin imparts its own chromatic identity to the stone.
Choosing a blue sapphire means choosing a story as much as a provenance.

Bonnot Paris has long made the blue sapphire its speciality.
Through our selection office in Beruwala, Sri Lanka, we are the only jewellery house in the world with direct access to stones immediately after cutting, before they reach the open market.

This privileged position allows us to select the finest blue sapphires available, according to exacting criteria:

• Stones that are eye clean, with no inclusions visible to the naked eye.
• No colour zoning, ensuring an even distribution of hue throughout.
• No or minimal windowing, guaranteeing homogeneous light diffusion.
• Well-balanced tones, neither too dark nor too light.

This standard of excellence makes every blue sapphire engagement ring a unique piece — at once rare and perfectly proportioned.

The majority of blue sapphires on the market are heat-treated, a traditional process that intensifies the colour and clarity of the stone.
However, unheated sapphires — left in their entirely natural state — are considerably rarer and more sought after.

The difference in value can be very significant:

• A heated Royal Blue sapphire of around 1.5 carats typically ranges between €2,500 and €3,500.
• The same stone in an unheated version can be worth more than three times as much, depending on colour and clarity.

Beyond 2 carats, rarity increases exponentially, and prices follow a similar progression.

Creating a blue sapphire engagement ring with Bonnot Paris means benefiting from a fully bespoke experience and direct, source-level stone selection.

An exceptional process

1. Sapphire selection: choice of colour, origin and carat weight according to your preferences.
2. Design conception: drawings, 3D rendering, selection of accompanying diamonds.
3. Artisanal crafting: executed in 18-carat gold or platinum, to the standards of haute joaillerie.

Our creations can be classic (solitaires, halos, three-stone) or entirely original, combining different sapphire hues or incorporating subtle colour accents.
Every ring is designed to reflect the personality of the person who will wear it.

Blue sapphire pairs beautifully with every precious metal:

• White gold and platinum to enhance the purity and cool freshness of the blue.
• Yellow gold for a warm and timeless contrast.
• Rose gold for a softer, more contemporary feel.

Each pairing creates a different balance between light and colour, brilliance and depth.

The price of a blue sapphire engagement ring depends principally on:

• the size of the stone,
• its hue,
• its origin,
• and its treatment status (heated or unheated).

As a guide:

• Heated pastel blue sapphire (approx. 1.5 ct): around €4,500.
• Heated Royal Blue sapphire: around €7,000.
• Unheated Royal Blue sapphire: between €10,000 and €12,000.

The larger the stone and the more saturated its colour, the more rapidly the price rises.
The setting (gold or platinum) and accompanying diamonds have a comparatively smaller influence on the final price.

With a hardness of 9 on the Mohs scale, the blue sapphire withstands daily wear with ease.
A simple clean with warm water and a mild soap is sufficient to preserve its brilliance.
An occasional ultrasonic bath with a jeweller will restore its full radiance.
