Halo Solitaire

Choosing an engagement ring is all about striking the right balance between style, stone, and metal. 18-karat gold rings set with diamonds or gemstones such as sapphires offer timeless elegance, perfect for a lasting commitment.

Every Deloison engagement ring is a unique creation, designed and crafted in Paris in our own workshop since 2020. We work exclusively with 18-karat white, yellow, or rose gold and select our diamonds and gemstones for their brilliance, character, and traceability. Unlike a traditional jewelry store, our Parisian workshop guides you through every step of the process: choosing the metal, the stone cut, the setting, and the engraving. The result is an 18-karat gold engagement ring that truly reflects your personality and will last a lifetime.

The diamond remains the quintessential stone for an engagement ring, prized for its brilliance and symbolic meaning. Whether it is a green sapphire with deep, earthy hues, a blue sapphire in its regal and timeless shade, or a teal sapphire with its two-tone shades of blue and green, it offers a refined and unique alternative to the diamond, perfect for an 18-karat gold piece of jewelry that expresses a distinct personality.

The solitaire showcases a single center stone in a sleek, timeless design. The halo solitaire highlights the stone with a ring of diamonds that enhances its brilliance. The pavé solitaire features a band set with diamonds, creating a continuous sparkle. Finally, the shoulder solitaire features diamonds on either side of the center stone, creating a balanced and luminous silhouette.

The diamond's shape—which jewelers refer to as the "cut"—is often the first decision to make, as it defines the character of the entire engagement ring. Here are the main ones:

The cut of the diamond round brilliant is the gold standard: 58 facets designed to maximize brilliance. It fits all settings and remains the most sought-after cut in Parisian jewelry.

The cut of the diamond elongated oval It visually accentuates the finger and offers a shine comparable to that of a round cut, with a more romantic and distinctive silhouette. 

The cut of the diamond emerald (rectangular with chamfered corners) highlights the stone’s purity rather than its shine—a bold and elegant architectural choice.

The cut of the diamond cushion (a square with rounded corners) is reminiscent of antique and vintage jewelry. Its luster is softer, warmer, and very flattering. 

The cut of the diamond pear combines roundness and slenderness. Worn with the tip pointing toward the fingernails, it is one of the most unique and flattering cuts for an engagement ring.

The cut of the diamond marquise is the most slimming of all; it creates a spectacular optical illusion on the hand.

At Delosion, we craft all these sizes in 18-karat gold, set in a style that enhances every facet of the gemstone.

The price of an 18-karat gold diamond engagement ring varies mainly based on the diamond’s weight and quality (color, clarity, cut), the type of setting, and the metal chosen. At DELOISON, our collection is designed for those seeking exceptional jewelry crafted in Paris, with pieces starting at just a few hundred euros for a sapphire engagement ring or several thousand for a high-quality diamond solitaire. We’ll help you find the perfect piece that fits your budget, without ever compromising on the highest standards of craftsmanship.

18-karat gold offers the perfect balance of purity, durability, and brilliance. It has become the standard in jewelry for pieces designed to be worn every day.

To celebrate a birth, a birthday, or a special occasion, an 18-karat gold ring set with diamonds or precious stones is a choice that is both symbolic and timeless. Solitaire rings, with their timeless elegance, are particularly cherished for marking a unique moment. Pavé or halo-set designs add extra sparkle, while rings set with sapphires offer a colorful alternative. Each creation thus becomes a meaningful piece of jewelry, designed to accompany life’s precious moments.
