As part of the limited-time Holiday 24-Hour Diamond Services program, clients will also receive a free GIA diamond display case, while supplies last.
The express service runs from November 10 to December 17, 2025, and is open to both shipped and walk-in submissions of natural, colorless diamonds. U.S. clients can participate by writing Promo Code: “HOLIDAY” on their memo and shipping box to receive their grading reports within 24 hours—at no additional charge.
To maintain this fast turnaround, stones will be processed and printed automatically, with no additional services added post-submission. Clients are advised to request any extras—such as inscriptions or AGS Ideal® reports—at intake. Each client may submit up to five stones per day, and standard shipping rates will apply.
