Lab Grown Diamond Necklaces

The Diyona Diamond Necklace Buyer's Guide

A diamond necklace is the piece you reach for without thinking: one stone on a fine chain for every day, or a full line of diamonds for the moments that call for more. Every necklace here is set with certified lab grown diamonds, made to order in solid gold, typically 40 to 70% less than mined. This guide covers necklace style, carat weight, and metal.

Choosing Your Necklace Style

Solitaire Pendants

A single lab grown diamond, set simply on a matching gold chain so one stone does the talking. It reads clearly at conversational distance and goes with everything, which is why it is so often the first fine jewelry piece.

Tennis Necklaces

A continuous line of round brilliant lab grown diamonds, each in its own four-prong basket on a flexible, secure line that follows the curve of the neck. Wear it alone or layered with shorter chains.

Choosing Your Diamond Shape

Round

The classic. A round brilliant catches light from every angle and never goes out of style: a timeless everyday pendant with zero fuss.

Oval

Elongated, so it looks larger for its weight and sits gracefully against the neck, with a touch more shape than a round.

Pear

The teardrop points gently downward as it hangs for a soft, flattering line; the setting protects both the rounded end and the point.

Emerald

Long, step-cut facets give a calm, refined sparkle of broad flashes rather than busy glitter. Because an emerald cut shows its clarity so openly, the lab grown price advantage goes into a cleaner, brighter stone.

Choosing Your Carat Weight

Pendants are quoted by the single center stone. Choose a 1 carat round, pear, or emerald diamond, or a 2 carat round or oval diamond.

Tennis necklaces are quoted as total carat weight, the combined weight of every diamond along the line, not the size of any one stone. Choose 6 or 10 carats total weight in round brilliant diamonds.

Choosing Your Metal

Every Diyona necklace is made to order in solid gold, and each pendant arrives on a matching gold chain. Tennis necklaces come in 14k white or 14k yellow gold: white reads icy and seamless with the diamonds, yellow gives a warm contrast that frames each stone. 14k is 58.5% pure gold alloyed for hardness, built for daily wear.

Frequently Asked Questions

Are lab grown diamonds real diamonds?

Yes. Lab grown diamonds are chemically and optically identical to mined diamonds. They're graded on the same 4Cs and have the same hardness (10 on the Mohs scale).

How long is the chain?

Every pendant arrives on a matching fine gold chain, ready to wear. If you have a specific length in mind, email care@diyona.com with the piece you're considering and we'll confirm before you order.

Do Diyona necklaces come with diamond certification?

Yes. Every solitaire pendant is set with a certified center diamond, and the diamonds in our tennis necklaces are certified as well. Look for "certified" on each product page.

Can I wear my necklace every day?

Yes. Diamonds are the hardest material (10 on the Mohs scale), and every necklace here is solid gold. To keep it bright, take it off for pools and harsh cleaners and store it separately to avoid scratching.

How long does delivery take?

Every necklace here is made to order, and your estimated ship date is shown on each product page and at checkout. U.S. orders ship free via UPS 2 Day, fully insured, with a signature required on delivery.

What is your return and warranty policy?
