FAQ

What occasions is the 18K Lab Diamond 3ct marquise pendant best suited for?

This pendant shines for formal and celebratory events—weddings, anniversaries, black-tie dinners, cocktail parties, and milestone birthdays. It also works as a luxurious gift (engagement/anniversary) or a signature piece for important business presentations or red-carpet style events. Because it’s a substantial 3ct marquise, many buyers treat it as a statement/special occasion piece rather than everyday jewelry.

How can I style this marquise pendant with different outfits and necklines?

For evening gowns or strapless dresses, wear the pendant alone to keep focus on the marquise center. Pair with a V-neck or scoop-neck top to echo the pendant’s shape and let it sit in the décolletage. For a modern look, layer with very fine chains of different lengths, and match with small diamond studs or a delicate bracelet to balance the statement. Avoid other large, competing pieces—this pendant works best as the focal point.

Can this pendant be used as an engagement or bridal piece?

Yes—its marquise cut and IGI certification make it a meaningful and verifiable option for engagement or bridal jewelry, especially for brides who prefer a pendant over a ring or want a matching pendant for wedding day wear. Confirm any personalization (engraving or custom chain length) with the seller, and consider pairing it with complementary lab-diamond rings or earrings for a coordinated bridal set.

How should I care for and maintain the pendant to keep it in top condition?

Remove the pendant before swimming, bathing, applying lotions or perfumes, and during physical activity. Clean gently with warm water, mild dish soap, and a soft brush; rinse and dry with a lint-free cloth. Store in its pouch or a separate compartment to avoid scratches. Have the setting and clasp professionally checked and cleaned every 6–12 months to ensure stones remain secure.

What does the IGI certification mean and how can I verify it?

IGI (International Gemological Institute) is an independent lab that grades diamonds—including lab-grown stones—on carat, cut, color, and clarity. The certificate documents the pendant’s 3ct marquise details and confirms lab-grown origin when applicable. Verify authenticity by checking the certificate number included in the full package on IGI’s website or requesting a copy from the seller. Keep the certificate for resale or insurance purposes.

Is the pendant suitable for daily wear and are there any allergy or durability concerns?

The 18K gold setting and lab diamond are durable, but 18K is softer than lower-karat alloys, so avoid rough wear. The 3ct marquise is sizable—it may catch on fabrics and can be more susceptible to knocks—so many people reserve it for regular but careful use rather than heavy daily wear. 18K gold is generally well tolerated, but if you have nickel sensitivity ask the seller about the alloy composition. For high-value pieces, consider adding insurance.
