J'ai contacté la bijouterie Bonnot car je souhaitais un saphir Padparadscha, qui est assez rare. Toute la transaction a été faite à distance et s'est très bien passée. Ils sont très professionnels, à l'écoute et très sympathiques. J'ai reçu ma bague et elle correspond tout à fait à ma demande. Merci beaucoup 😋

FAQ - BLUE SAPPHIRE ENGAGEMENT RINGS

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

But beyond its symbolism, the blue sapphire captivates with its unique brilliance.
Its colour, both deep and luminous, has no equivalent among other precious stones.
It is a gemstone of character, giving every ring a strong and instantly recognisable style.

The blue sapphire offers an exceptional palette of shades, ranging from pastel blue to the most intense blue.
Each colour tells a story of emotion, temperament and style.

  • Pastel blue: delicate and luminous, for a ring full of softness.
  • Ceylon blue: vivid brilliance, slightly light, emblematic of Sri Lanka.
  • Cornflower blue: velvety blue, elegant and refined.
  • Royal Blue: deep, intense, a symbol of jewellery-making tradition.
  • Peacock blue: subtle green reflections, for a more distinctive creation.
  • Kashmir blue: a legendary, rare and sought-after hue, with incomparable velvety softness.

Shade directly influences a sapphire’s value: the most saturated, luminous and balanced shades are the most coveted.

The teal sapphire is a superb alternative to the traditional blue sapphire. Its blue-green hue, both subtle and distinctive, makes it a truly unique stone.

The padparadscha sapphire, meanwhile, is one of the rarest and most coveted. Its delicate hue, blending pink and orange, evokes the colour of a sunset or a lotus flower — from which it takes its name. An exceptional gemstone, it appeals to connoisseurs seeking originality and refinement.

Blue sapphire shades

The finest blue sapphires come from renowned deposits:

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

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

At Bonnot Paris, blue sapphire is a longstanding speciality.
Thanks to our selection office in Beruwala, Sri Lanka, we are the only fine jewellery house in the world with direct access to stones as soon as they are cut, before they are brought to market.

This privileged position enables us to choose the finest blue sapphires available, according to exceptionally exacting criteria:

  • Eye-clean stones, with no inclusions visible to the naked eye.
  • No colour zoning.
  • No or very few “windows”, ensuring even light distribution.
  • Balanced shades, neither too dark nor too light.

This exacting standard makes every blue sapphire engagement ring a unique piece, both rare and perfectly proportioned.

The majority of blue sapphires on the market are heated, a traditional treatment that enhances the stone’s colour and clarity.
But unheated sapphires — left in their natural state — are far rarer and more sought-after.

The difference in value can be highly significant:

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

Above 2 carats, rarity increases exponentially, with prices following a similar progression.

Creating a blue sapphire engagement ring at Bonnot Paris means benefiting from bespoke guidance and direct selection at the source.

An exceptional process

  1. Sapphire selection: choosing the colour, origin and carat weight according to your preferences.
  2. Design development: sketch, 3D rendering, selection of accent diamonds.
  3. Artisanal craftsmanship: created in 750 gold or platinum, in keeping with high jewellery standards.

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

Blue sapphire pairs beautifully with all precious metals:

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

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

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

  • the stone’s size,
  • its shade,
  • its origin,
  • and its condition (heated or unheated).

As a guide:

  • Heated pastel blue sapphire (approx. 1.5 ct): approximately €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 accent diamonds have a lesser influence on the final price.

Thanks to its hardness of 9 on the Mohs scale, blue sapphire is perfectly suited to daily wear.
Simple cleaning with lukewarm water and mild soap is enough to preserve its brilliance.
An occasional visit to a jeweller for an ultrasonic cleaning will restore its sparkle.

Bonnot Paris offers the expertise of its gemmologists to guide you through the creation of a blue sapphire engagement ring that reflects you.
Each stone is hand-selected directly in Sri Lanka to guarantee quality, traceability and absolute beauty.
