Color, stone dimensions, setting, and accent diamonds can change the appearance of gemstone jewelry. Confirm the stated gemstone and any origin or treatment disclosures on each listing. You can view a matching design as a starting point.

Compare the available size, band width, and height. If you plan to stack rings, check that their profiles and settings fit comfortably together. You can also compare related styles.

Read the stated metal, karat where applicable, gemstone type, dimensions, and any treatment or origin information. Natural and laboratory-grown stones should be identified by the individual listing. If anything is unclear, contact Mervis for details about that item.

Store pieces separately and protect them from impacts and harsh chemicals. Follow care guidance for the exact materials and settings, and have loose stones or damaged fastenings assessed before further wear. You can ask about jewelry care and repairs for the individual piece.

You can book a Mervis appointment to discuss the styles you are considering. Contact the showroom beforehand about specific pieces, since online listings do not confirm availability at each location.
