A classic oval diamond solitaire designed to keep the attention on one beautifully proportioned center stone. This necklace features an 8 × 6 mm oval lab-grown diamond weighing approximately 1 1/4 carats, selected to F+ color and VS clarity.

The elongated oval feels refined without a halo or accent stones. A polished four-prong claw-prong bezel-style setting keeps the diamond's outline visible.

Choose sterling silver, 14K yellow gold vermeil, solid 10K white or yellow gold, or solid 14K white or yellow gold. Every option features the same lab-grown diamond and an 18-inch cable chain in the selected metal.

Why the Solitaire Design Works

With no halo or secondary stones competing for attention, the oval diamond becomes the entire focal point. The design is clean enough for regular wear, polished enough for milestone gifting, and easy to layer without losing its identity when worn alone.

Why Lab-Grown Diamond?

Lab-grown diamond has the same optical and chemical properties as mined diamond, with a different origin. It offers meaningful diamond presence—approximately 1 1/4 carats with F+ color and VS clarity—at a more approachable price than a comparable mined-diamond necklace.

Also Meaningful for April

Diamond is the traditional April birthstone and is often associated with strength, clarity, endurance, and lasting love.

Please Note the Scale

Product photography is enlarged to show the diamond and setting details. The center diamond measures 8 × 6 mm. Including the setting, the finished pendant is approximately 9.1 mm from top to bottom—roughly the size of a fresh blueberry, but with a flatter, elongated oval profile—and about half the diameter of a U.S. dime.

Shipping & Availability

Many metal selections may arrive within approximately 3–5 business days. Availability varies and will be confirmed after your order is placed. If you need the necklace by a particular date, contact Matt before ordering so we can confirm the current timeline.

Choosing Your Metal

Sterling silver and 14K yellow gold vermeil offer the same design at a more approachable price. Solid 10K and 14K gold are available in white or yellow gold and have no plated sterling-silver base. The gemstone specifications remain the same across the metal options; choose according to your preferred color, metal composition, care, and budget.

Why It Earned a Place in Our Collection

A single oval diamond solitaire is one of the most versatile necklace designs: no halo, no trend-led detail, and no competing accent stones. The eye goes directly to the approximately 1 1/4 CT lab-grown diamond, selected to F+ color and VS clarity.

The 8 × 6 mm oval has a graceful, softly elongated shape, while the polished four-prong claw-prong bezel-style setting keeps the diamond visually open. An 18-inch cable chain makes it easy to wear on its own or layer with other necklaces.

14K yellow gold vermeil is gold over sterling silver, not solid gold. Solid 10K and 14K options have no sterling-silver base and are available in white or yellow gold. Gemstone specifications remain the same across the metal options.

Wear & Care

Remove the necklace before showering, swimming, exercising, or using household chemicals. Apply lotions and fragrances before putting it on, wipe gently after wear, and store separately. Vermeil requires extra care to preserve its appearance; sterling silver may be polished with a silver-safe cloth. Clean solid gold gently with a soft cloth and mild jewelry-safe solution when needed. White gold may have a rhodium-plated finish.
