FAQ

Is the ZKZ 18K white gold marquise lab-grown diamond ring suitable for everyday wear?

Yes — lab-grown diamonds have the same hardness (10 on Mohs scale) as mined diamonds, so the stone itself is very durable. Because the ring is set in 18K white gold, take care with hard knocks and abrasive tasks; remove it for heavy manual work, sports, and harsh chemicals. Regular inspection of prongs and settings helps keep it secure for daily wear.

Can this ring be resized or otherwise customized?

As a custom jewelry piece, resizing and personalization are usually available, but there are limits. Marquise shapes and rings with side stones or intricate settings may require careful work to resize without affecting symmetry. Contact ZKZ or the seller before purchase to discuss exact size, engraving, metal choice, or design changes and to confirm turnaround time and cost.

How should I clean and maintain the ring to keep it looking its best?

Clean gently with warm water, mild soap, and a soft brush; rinse and dry with a lint-free cloth. Professional cleaning and inspection every 6–12 months is recommended. Because 18K white gold is often rhodium-plated for colour and shine, you may need rhodium re-plating occasionally to restore the finish. Avoid ultrasonic cleaners if the setting or side stones are delicate — ask your jeweler first.

For what occasions or styles is the marquise lab-grown diamond ring best suited?

It is ideal as an engagement ring and for proposals, weddings, anniversaries, and milestone gifts. The marquise cut visually elongates the finger and works well with both classic and vintage-inspired styles. It also functions as a statement or cocktail ring for formal events, and can be styled with stacking bands or a matching wedding band for everyday elegance.

Are lab-grown diamonds safe and ethical compared to mined diamonds?

Lab-grown diamonds are chemically, physically, and optically the same as mined diamonds and are very durable for everyday wear. They are often marketed as a more sustainable and traceable option because they avoid many environmental and social impacts associated with some mining. Check the product listing for any grading report or traceability information provided by ZKZ for full transparency.

How will this ring pair with wedding bands and other jewelry?

The 18K white gold finish pairs best with white gold, platinum, or silver-toned bands for a seamless look. A contoured or curved wedding band can fit snugly against a marquise setting; plain or tapered bands complement it nicely. If you want a flush fit or matching set, request a bespoke wedding band or have a jeweler contour a band to the ring’s profile.
