Yes, ruby is an excellent choice. With a hardness of 9 on the Mohs scale, it is the most durable gemstone after diamond, making it ideal for a ring worn every day. Its intense red colour also makes it a powerful symbol with which to mark a lifelong commitment.
Ruby embodies passion, ardent love and desire. Revered since antiquity as the stone of the deepest emotions, it symbolises a profound and enduring love — a particularly meaningful choice for a marriage proposal.
The price depends on several factors: the size of the stone (in carats), its colour, clarity, origin and the metal chosen for the setting. At Bonnot Paris, we work directly, without intermediaries, to ensure the fairest price. Request a personalised quote for an estimate tailored to your project.
A ruby's quality rests principally on its colour: the most sought-after stones display a vivid, intense red known as 'pigeon's blood'. Clarity (the absence of visible inclusions), cut and brilliance also play an important role. A certificate issued by an independent gemmological laboratory guarantees its authenticity and characteristics.
Yes. All our rubies are certified by independent gemmological laboratories, providing assurance of their authenticity and quality. We select our stones directly through our offices in Sri Lanka, Bangkok and Jaipur, as close to the source as possible.
Every metal flatters a ruby beautifully. White gold and platinum enhance the contrast with the stone's red, yellow gold brings a warm and classic touch, while rose gold creates a soft and romantic harmony. The choice comes down to your personal taste — our experts are here to help you find the perfect match.
Allow an average of four to six weeks for a bespoke creation, from stone selection through to delivery of your ring. Every project begins with a dedicated consultation with our experts, by appointment or via video call.
Clean your ring with warm soapy water and a soft brush, then dry it gently. Avoid harsh chemicals and knocks. For a thorough clean, we recommend entrusting your ring to a professional jeweller.
