This Express Office, GCAL’s second location in the building, was opened to provide more transparent and accessible “while you wait” diamond, gemstone, & jewelry services to the trade and consumers, alike, according to Angelo Palmieri, Vice President and Chief Operating Officer.

Services being offered in the Express Office are as follows:

  1) Sarin Label/Manufacturer’s Report
  2) Gemprint Registration & Verification
  3) Optical Brilliance Analysis
  4) Optical Symmetry Analysis
  5) Photomicrographs (Crown & Pavilion)
  6) Hearts & Arrows Analysis

The reports are attractively packaged and are available on the spot.

For consumers or jewelers who need immediate and accurate precious metal value, GCAL utilizes the latest state-of-the-art Niton GOLDD™ XRF Analyzer, and along with a constant feed of World Spot Precious Metal prices, can produce a report that provides the metal content value.

The GCAL Express Office utilizes the same ISO practices and procedures for Quality Assurance as in the main GCAL Laboratory located in the Lower Lobby.

With the vision and tremendous support from the World Diamond Tower management and owners, GCAL was able to capture prime lobby space from a long forgotten elevator shaft hidden behind a stone façade for decades.
