Diamond Tennis Necklace

Every stone. Every inch. All diamond.

There is no piece of fine jewelry more universally coveted, or more instantly transformative, than the diamond tennis necklace. The AVRA Diamond Tennis Necklace is its finest modern expression: a continuous line of round brilliant lab-grown diamonds, each hand-selected for EF color and VS clarity, set in solid 14K gold prongs that lift every stone toward the light. From the first stone to the last there is no gap, no break, no interruption. Just an unbroken river of white light sitting exactly where you want to be looked at.

✦ Diamond Specifications

• Stone: Round brilliant lab-grown diamonds, individually matched across the line
• Clarity: VS+, eye-clean from every angle
• Color: EF+, near-colorless and bright white
• Cut: Excellent
• Carat weight: 4, 5, 7, 10, 15, 20 or 25 ctw
• Setting: Four-prong open baskets, so light enters from beneath the stone as well as above it

Carat weight here is spread across the entire length rather than concentrated in one stone. At 4ct the line reads fine and quiet along the collarbone. From 15ct upward it becomes the first thing anyone registers about you.

✦ Metal & Construction

• Solid 14k gold throughout, in yellow or white. Not plated, not filled, not vermeil.
• Available at 16", 18" and 20". Sixteen inches sits at the base of the throat, twenty falls just below the collarbone.
• Every setting is linked individually, so the necklace articulates and follows the curve of your neck instead of standing away from it.
• Closed with an underlock, a concealed box clasp with a safety catch. It tucks into the diamond line so there is no visible break at the back.

✦ How to Wear It

On bare skin, at 16", with a plain black dress and nothing else. That is the version of this necklace people remember. At 18" it sits beautifully over a fine knit or a crew neck, which is the easiest way to wear real diamonds on a Tuesday without feeling costumed.

Match it with the Lumière Tennis Bracelet if you want the full continuous-line look, or let the Monroe collar sit above it for a deliberate two-necklace stack. One rule worth keeping: nothing busy near it. A tennis necklace does not share a neckline well, and it does not need to.

✦ Why Lab-Grown Diamonds

• Chemically and optically identical to mined diamonds. Same carbon structure, same 10 on the Mohs scale, same fire.
• Graded on the same 4Cs by the same gemological standards, which is how we can promise EF/VS across every stone.
• Traceable origin. You know exactly where each diamond came from.
• Meaningfully better value, which is the entire reason a 20 or 25 carat tennis necklace can be something you own rather than something you look at online.

✦ Perfect For

• The promotion, the exit, the year the numbers finally worked. This is a piece women buy themselves to mark something.
• Black-tie, galas and the dinner where you want to arrive already finished.
• Your own wedding, worn against a bare neckline instead of a traditional pendant.
• Milestone birthdays and anniversaries, especially the ones you are celebrating on your own terms.
• Ordinary weekdays, if that is who you are. Plenty of women never take theirs off.

✦ Care & Longevity

• Solid 14k gold will not tarnish or fade. It simply needs cleaning.
• Wash with warm water, a drop of mild soap and a soft toothbrush. Work along the underside of the settings, where lotion and skin oils collect and dull the light.
• Put it on last, after perfume, hairspray and sunscreen. Take it off before swimming. Chlorine attacks the alloys in gold over time.
• Store it flat in your AVRA box rather than coiled, so the articulated line does not kink.
