BLUE SAPPHIRE ENGAGEMENT RINGS

The blue of the sapphire is universally associated with nobility of feeling and strength of commitment.
It embodies trust, fidelity and serenity — qualities that make it the ideal stone to symbolise a lifelong promise.

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

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

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

The shade directly influences the value of the sapphire: the most saturated, luminous and balanced hues are the most sought after.

The teal sapphire is a magnificent alternative to the traditional blue sapphire. Its blue-green hue — subtle yet distinctive — makes it a truly unique stone.

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

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

• Sri Lanka (Ceylon): light to medium blues of exceptional luminosity.
• Madagascar: a wide diversity of tones, from pastel blue to Peacock blue.
• Burma (Mogok): dense blues with rich saturation.
• Kashmir: a historic deposit now exhausted, whose stones rank among the rarest in the world.

Each origin gives the stone its own chromatic identity.
Choosing a blue sapphire is also choosing a provenance — and a story.

Bonnot Paris has a longstanding speciality in blue sapphire.
Through our selection office in Beruwala, Sri Lanka, we are the only fine 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 choose 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 the stone.
• Minimal or no windowing, guaranteeing a homogeneous diffusion of light.
• Balanced tones — neither too dark nor too light.

This level of rigour makes every blue sapphire engagement ring a one-of-a-kind piece — 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.
Unheated sapphires — left in their 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, with prices rising in a similar progression.

Creating a blue sapphire engagement ring at Bonnot Paris means benefiting from a fully bespoke service and direct stone selection at source.

An exceptional process

1. Sapphire selection: choice of colour, origin and carat weight according to your preferences.
2. Design: sketches, 3D rendering, choice of accompanying diamonds.
3. Crafting: realised in 18-carat gold or platinum, to the standards of high jewellery.

Our creations can be classic (solitaires, halos, three-stone settings) or original, combining different sapphire shades or subtle colour accents.
Every ring is conceived to reflect the personality of the person who wears it.

Blue sapphire pairs beautifully with every precious metal:

• White gold and platinum to enhance the purity and freshness of the blue.
• Yellow gold for a warm, timeless contrast.
• Rose gold for a contemporary and softly romantic touch.

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

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

• the size of the stone,
• its hue,
• its origin,
• and whether it is 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 any accompanying diamonds influence the final price to a lesser degree.

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