New York—The Gemological Institute of America is offering one-day turnaround on diamonds submitted to its Carlsbad and New York laboratories for the next couple weeks.

GIA said D- to Z-color diamonds received at either of the labs for a diamond grading report or Diamond Dossier service will be ready for pickup with the grading report enclosed within 24 hours of receipt (weekdays only) at no additional charge.

The one-day turnaround offer is available now through Dec. 19, though it does not apply to grading reports online, which may take longer than a day to access.

Return shipping is available at normal ship times following 24-hour grading service, utilizing standard shipping policies. Diamonds have to be shipped from, and returned to, a single address in the United States.
