An elegant procession of oval, emerald, marquise and pear lab grown diamonds flows into a brilliant oval centerpiece, creating a Riviera necklace that feels graceful from every angle. The mixed fancy-cut layout adds texture and movement while keeping the design refined and balanced.
The oval center is framed by a delicate pavé halo that subtly amplifies its brilliance before leading into a slender articulated drop. Every transition between shapes is intentional, giving the necklace a fluid silhouette that sparkles differently with each movement.
Handcrafted to order in your chosen precious metal, this statement necklace is designed for weddings, anniversaries and milestone celebrations while remaining timeless enough to treasure for generations.
Design Highlights
The halo creates a soft frame around the oval center while the diamond drop introduces graceful movement, making this design captivating whether viewed from the front or in motion.
Oval diamonds combine brilliant faceting with an elongated outline that appears larger than many other shapes of the same weight. Paired with emerald, marquise and pear diamonds, they create a sophisticated balance of sparkle and elegant lines.
Every Signora diamond is lab grown—chemically, physically and optically identical to a mined diamond, graded using the same international standards, and responsibly created without mining.
Available in Sterling Silver, 9K, 14K and 18K Gold in yellow, white and rose, plus Platinum. Crafted at approximately 16 inches with custom sizing available upon request. Clean gently with warm water, mild soap and a soft brush, then store separately to preserve its brilliance.
What makes this necklace different from a traditional Riviera?
This design combines multiple fancy-cut diamonds instead of using a single shape throughout. The result is a more dimensional appearance with varied flashes of brilliance.
What is the center stone?
The centerpiece is a 9.40 × 6.40 mm oval lab grown diamond weighing approximately 1.55 carats, surrounded by a delicate halo of round diamonds.
Can I request a different necklace length?
Yes. Although this necklace is crafted at approximately 16 inches, custom lengths can be made to order.
Are lab grown diamonds real diamonds?
Yes. They have the same chemical composition, hardness and brilliance as mined diamonds and are graded using the same international standards.
Is the clasp secure?
Yes. The necklace is finished with a spring ring clasp that provides reliable everyday security while maintaining a refined appearance.
Is this suitable for bridal wear?
Absolutely. The elegant halo centerpiece, articulated drop and over 14 carats of lab grown diamonds make it a beautiful choice for weddings, receptions and formal occasions.
