The 8mm Lab-Grown Diamond Cuban Link is a fully iced-out white gold Cuban set with real, IGI-certified lab-grown diamonds. Slim, everyday, still hits. If you want genuine diamond shine in a chain you can actually wear on repeat, this is it.

What makes it

• Set link to link with VVS lab-grown diamonds—real diamonds, grown in a lab, with the same fire and hardness as mined stones.
• Every chain comes with an official IGI certificate, the recognized grading lab for diamonds.
• White gold plating over a 925 sterling silver base—a clean, icy tone at a wearable 8mm width.
• A secure box clasp keeps it locked while you move.

Lab-grown vs mined diamond

• Same diamond, different origin—lab-grown diamonds are chemically and optically identical to mined diamonds, with the same hardness (10 Mohs) and the same fire, grown in weeks instead of mined from the earth.
• Every stone is IGI-certified for documented VVS clarity.
• Because they're lab-grown, you get real diamond at a fraction of the mined-diamond cost.

Who it's for

8mm is the everyday sweet spot—real diamond shine without the bulk of a statement chain. 16–18" sits high like a choker, 20–22" is the classic length, and 24" gives a longer drape. With its IGI certificate and gift box, it also lands as a documented, ready-to-give gift. Explore more IGI-certified pieces in our lab-grown diamond necklaces collection.

Style & care

Wear it solo for a clean iced look, or layer it with a matching tennis chain for extra shine. To keep the white gold bright, store it dry, wipe it after wear, and take it off before showering or heavy sweat. Keep it away from chlorine, perfume, and harsh chemicals, which dull any plated finish faster—treated with care, it holds its bright white tone far longer.

FAQ

• Are these real diamonds? Yes—lab-grown diamonds are real diamonds, chemically identical to mined ones, and each chain is IGI-certified.
• What certificate does it come with? An official IGI certificate.
• Does the white gold plating wear off? Like all plated jewelry, the finish wears gradually with heavy use; kept dry and clean it holds its bright tone for a long time, and it can be re-plated later.
• How should I store it? Keep it in its box or a soft pouch, apart from other chains, so the plating and stones stay scratch-free.
• What lengths can I get? 16", 18", 20", 22", and 24".

Is your jewelry real?

Yes. Most of our jewelry is made with S925 sterling silver and set with VVS moissanite stones. Some selected styles may use high-quality brass with 18K gold plating. Please check each product description for the exact material.

Are the stones real diamonds?

Our stones are VVS moissanite, not natural diamonds. Moissanite has excellent fire and brilliance, giving a diamond-like shine at a more affordable price. See how the two compare in our moissanite vs diamond guide.

Does the jewelry come with a certificate?

Most moissanite pieces come with a GRA certificate. If the item includes a certificate, it will be shown in the product photos or description.

Will the jewelry fade?

To keep every piece looking its best, avoid swimming, showering, sweating, or exercising while wearing it, and store it in the jewelry pouch when not in use. Gold-plated styles are finished with multiple layers of plating for long-lasting shine, while sterling silver styles keep their natural finish.

How long do custom pieces take?

Custom pieces usually take around 15–30 business days to produce after your design is approved, depending on the design and details. We'll confirm the estimated timeline before you place your order. Ready to design your own? Start a custom piece.
