FAQ

Can I wear the ZKZ 18K white gold marquise lab-grown diamond pendant every day?

Yes — the pendant is designed for regular wear, but treat it like fine jewelry. Remove it for heavy physical activity, sports, swimming (especially in chlorinated or salt water), and when using harsh chemicals or cleaning products. Avoid contact with perfumes and lotions right after application to keep the rhodium finish and diamond sparkle longer.

What occasions and outfits does this pendant work best with?

The marquise lab-grown diamond pendant is versatile: it elevates everyday work or casual looks, pairs beautifully with cocktail and evening attire, and is elegant enough for formal events such as weddings. For a minimalist daytime look wear it alone on a short chain; for formal occasions layer with a longer chain or pair with matching earrings to create a more dramatic effect.

How should I clean and maintain the 18K white gold and the lab-grown diamond?

Clean gently with warm water, a mild dish soap, and a soft brush; rinse and dry with a lint-free cloth. Avoid ultrasonic cleaners if the setting is delicate. White gold often has a rhodium plating to enhance whiteness — this plating can wear over time and may need re-plating every 1–5 years depending on wear. Have the setting and stone inspected regularly by a jeweler to ensure prongs are secure.

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

IGI (International Gemological Institute) certification documents the diamond’s grading (cut, color, clarity, carat weight). The pendant comes with an IGI report that you should keep with your purchase records. You can usually verify the report online through IGI’s website using the report number, or ask the seller for a digital copy and verification link.

Can I customize the pendant (chain length, engraving, or metal options)?

Many sellers offer customization such as different chain lengths or alternative metals. Engraving on the pendant’s back may be possible depending on its surface area. If you have metal sensitivities, request nickel-free white gold or consider 18K white gold alloyed with palladium. Contact ZKZ or your retailer to confirm which customization and metal options are available and whether additional lead time or fees apply.

Is this pendant a good gift and how should it be stored or insured?

Yes — the IGI-certified lab-grown diamond pendant makes a meaningful gift for anniversaries, graduations, engagements, and special milestones. It often comes in presentation packaging; ask the retailer about gift wrapping. For long-term protection, store the pendant in a soft pouch or separate compartment to avoid scratches. For high-value pieces, obtain an appraisal and consider jewelry insurance to protect against loss, theft, or damage. Keep photos and the IGI certificate in a secure place for claims.
