As part of our commitment to exceptional customer service, GHI offers expedited and individualized service options.

ADVANCED TESTING

Supplement your stone’s analysis with a request for typing or treatment detection. Aspects such as clarity or color enhancement, or lab-grown origin can be documented in a lab letter or report.

LASER INSCRIPTION

Personalize a stone with a microscopic message, brand name, or registration number.

RECHECK

Confirm previous results by resubmitting stones for further gemological review.

RUSH SERVICE

Prioritize your submission, with preliminary results or a full report delivered in either 24 or 48 hours.

STONE MARKING

Learn more about your stone via markings that note the location of inclusions, treatments, or areas that could benefit from a revised cut.

VERIFICATION

Resubmit your stone and report for a confirmation analysis and (assuming the items match) an official lab verification letter.
