- Categories : Jewelry News Rss feed , Know your jewelry Rss feed

There are jewels that go beyond tradition. The ruby solitaire is one of them. With its deep, vibrant red, symbolizing passion, it stands out as a bold and colorful alternative to the classic engagement ring. Paired with sparkling natural diamonds, it becomes a truly unique fine jewelry piece. At Celinni, a diamond expert for six generations, the ruby and diamond solitaire embodies Parisian elegance at its finest.

Pourquoi choisir un solitaire rubis pour ses fiançailles ?

Why Choose a Ruby Solitaire for Your Engagement?

For decades, the white diamond has dominated the world of engagement rings. However, a new generation of couples is looking to break away from tradition—without compromising on the nobility of precious materials. The ruby solitaire perfectly answers this desire.

Ruby: The Gemstone of Love and Passion

Ruby belongs to the family of the four precious gemstones, alongside diamond, sapphire, and emerald. Its intense red hue, caused by traces of chromium, gives it an immediate visual impact. Since ancient times, it has been associated with passion, vitality, and deep love. Offering a ruby solitaire is a powerful way to express a love that is intense, alive, and enduring.

Ruby is also the birthstone for July, making it a highly symbolic gift for those born in this month. With a hardness of 9 on the Mohs scale—just below diamond—it is a durable gemstone, perfectly suited for everyday wear as an engagement ring.

A Rare Jewel That Stands Out Instantly

Unlike the traditional diamond solitaire, which remains widely popular, the ruby and diamond solitaire is a truly distinctive piece. It naturally draws attention. The contrast between the deep red of the ruby and the brilliance of white diamonds creates a luminous and sophisticated effect, characteristic of fine French jewelry. Wearing such a ring reflects a strong sense of style and a unique personality.

Iconic Ruby Solitaire Designs by Celinni

At Celinni, the precious gemstone solitaire collection showcases several iconic ruby designs. Each piece is handcrafted in the Maison’s workshops, following the highest standards of Parisian fine jewelry.

The Promise Ruby Solitaire

Timeless and classic, the Promise Solitaire features a natural round brilliant ruby, held by four elegant prongs. Its clean design focuses all attention on the central stone, whose deep red symbolizes an everlasting promise of love. It represents the pure essence of a ruby solitaire: simple, powerful, and unforgettable. Available in 18K yellow gold, white gold, rose gold, or platinum 950.

The Ma Vie Ruby Solitaire — Halo Version

For those seeking a more striking effect, the Ma Vie Ruby Solitaire showcases a central ruby enhanced by a halo of natural diamonds. This circular setting creates an illusion of greater volume, amplifying the presence of the stone. The result radiates warmth and brilliance. This engagement ring is a true statement piece of Parisian jewelry, perfect for both everyday wear and special occasions.

The Eternal Ruby Solitaire

The Eternal Solitaire takes a bold, modern approach with an airy setting that allows the ruby to appear as if it is floating above the band. This design highlights the gemstone from every angle, enhancing its brilliance and light. It symbolizes eternal love—endless and continuous—just like the ring that carries it.

The Destinée Ruby Solitaire — Parisian Halo Style

The Destinée Solitaire combines a delicate 18K gold or platinum band with a halo of diamonds surrounding the central ruby. This refined and classic design is a staple of Parisian jewelry. The halo enhances the depth of the ruby’s red color while increasing the perceived size of the stone. A timeless piece that will remain elegant for generations.

Ruby and Diamond Solitaire: How to Choose the Right Ring

Choosing an engagement ring is an emotional decision, but a few key criteria can help you find the perfect ruby solitaire.

Natural Ruby Quality: What to Look For

All rubies offered by Celinni are 100% natural, with no synthetic treatments or substitutes. A high jewelry-quality ruby is defined by three essential factors:

  • Color: The highly sought-after “pigeon blood” red—deep, vivid, and slightly purplish—represents the highest quality. The richer and more even the color, the more valuable the ruby.
  • Clarity: As with diamonds, the fewer visible inclusions, the higher the value. Perfectly clear rubies are extremely rare.
  • Origin: Burmese rubies (Myanmar) are historically the most prized for their exceptional color. Rubies from Thailand and Mozambique are also highly appreciated.

Choosing the Metal: Gold or Platinum?

Ruby pairs beautifully with several precious metals, each offering a distinct aesthetic:

  • 18K Yellow Gold: Creates a warm and luxurious harmony with the ruby’s red tones. This is the most traditional and luminous setting.
  • 18K White Gold: Provides a striking contrast that enhances the ruby’s color with a modern, elegant touch.
  • 18K Rose Gold: Adds a soft, romantic, and feminine feel—very on-trend.
  • Platinum 950: The most noble and durable metal. It highlights the brilliance of the surrounding diamonds with refined simplicity.

Ruby Cut and Setting

The round brilliant cut is the most popular choice for ruby solitaires, as it maximizes the gemstone’s brilliance. Cushion, oval, or pear cuts are also excellent options for a more distinctive look.

Prong settings remain the most classic, allowing light to pass through the stone and enhance its sparkle. Halo settings, surrounded by diamonds, are ideal for those who want a more visually striking ring.

Ruby and Diamond: A High Jewelry Duo

One of the greatest strengths of the ruby and diamond solitaire lies in the natural harmony between these two gemstones. The bright white brilliance of diamonds enhances the deep red of the ruby through a powerful contrast. This combination creates a luminous and dynamic effect that makes the ring instantly recognizable.

At Celinni, all diamonds paired with rubies are certified natural stones, carefully selected from over 100,000 options available on international diamond exchanges. Each diamond is chosen based on its cut, color, clarity, and brilliance to perfectly enhance the central gemstone.

This commitment to excellence defines the signature of Celinni, reflected in both its diamond solitaires and its entire engagement ring collection.

Caring for a Ruby Solitaire: Practical Tips

A ruby solitaire is designed to last a lifetime—provided it receives proper care.

How to Clean Your Ruby Ring

Regular cleaning helps maintain the brilliance of both the ruby and the diamonds. Simply soak the ring in warm water with mild soap, gently brush it with a soft toothbrush, and rinse thoroughly.

Avoid ultrasonic cleaning for rubies that have been treated with resin or cedar oil.

Everyday Precautions

Although ruby is a very hard gemstone, it is not indestructible. Avoid wearing your ring during activities that may cause impact, such as sports, DIY work, or gardening. Store it separately from other jewelry to prevent scratches.

FAQ — Ruby Solitaire: Your Questions Answered

What is the difference between a ruby solitaire and a diamond solitaire?

A ruby solitaire features a natural ruby as its center stone, while a diamond solitaire is set with a white diamond. The ruby brings a vibrant color and symbolizes passion and love, whereas the diamond represents purity and eternity. The two can also be combined: a ruby and diamond solitaire blends the ruby’s rich color with the brilliance of surrounding diamonds.

How much does a natural ruby solitaire cost at Celinni?

The price of a ruby solitaire at Celinni depends on several factors: the ruby’s carat weight, quality (color, clarity, origin), the chosen metal (18K gold or platinum), and the design. Thanks to direct sourcing from international diamond exchanges, prices are typically up to 70% lower than those of major jewelry houses, for equivalent quality. You can contact an expert for a personalized quote.

How can you tell a natural ruby from a synthetic one?

A natural ruby contains microscopic inclusions that can be observed under a gemologist’s loupe. It is also certified by an independent laboratory confirming its natural origin. A synthetic ruby, created in a lab, has the same chemical structure but not the same rarity or value. At Celinni, all rubies are 100% natural and delivered with a certificate of authenticity.

Is a ruby solitaire suitable for everyday wear as an engagement ring?

Yes, absolutely. Ruby has a hardness of 9 on the Mohs scale, making it highly resistant to scratches and perfectly suited for daily wear. Combined with an 18K gold or platinum setting—both very durable metals—a ruby solitaire is designed to last for years without losing its brilliance.

Can I order a custom ruby solitaire from Celinni?

Yes. Celinni offers a bespoke design service for all gemstone solitaires. You can choose your ruby (carat weight, color, origin, cut), the setting (18K yellow, white, or rose gold, or platinum), the style (prong, halo, bezel), and the accompanying diamonds. Book an appointment in one of the boutiques in Paris, Nice, Lille, or Lyon to be guided by a jewelry expert.

What is the most sought-after ruby color in fine jewelry?

The most desirable color in high jewelry is known as “pigeon blood” red—a deep, vivid red with slight purplish undertones and exceptional richness. This rare hue is most commonly associated with rubies from Myanmar (Burma). The more intense and evenly saturated the color, the more valuable and sought-after the ruby is among collectors and jewelry lovers alike.
