FAQ Section
A grading report from the Gemological Institute of America (GIA) acts as an undisputed, global passport for your diamond. Because the GIA is a non-profit, independent research entity, their strict color, clarity, cut, and carat weight grading standards are trusted implicitly by wholesale markets worldwide. When you bring a GIA certified stone to our Houston showroom, it eliminates grading speculation. This definitive proof allows our jewelry appraisers to offer you the absolute top market value, as we don't have to factor in "grading risks" or safety margins that uncertified stones often require.
Â
Yes, absolutely. The physical paperwork is convenient, but it is not required to complete a sale. Most GIA certified diamonds graded over the last few decades have their unique, 10-digit GIA report number microscopically laser-inscribed directly onto the stone’s outermost edge (the girdle). When you bring your diamond to our Houston office, our specialists will place your stone under a high-powered gemological microscope, read the laser inscription registry in your presence, and instantly pull up your exact digital dossier online.
We buy both. We routinely purchase loose GIA certified stones as well as complete GIA diamond engagement rings, custom pendants, earrings, and heirloom estate jewelry. When evaluating a set diamond, our local buyers calculate the premium wholesale value of the GIA certified center stone and combine it with the scrap value of the gold or platinum mounting. If the ring itself is a signed designer piece (such as Tiffany & Co., Cartier, or Harry Winston), we will add a secondary brand premium to your final cash offer.
Every GIA grading report features a highly detailed, unique blueprint of the diamond, which includes a precise proportion diagram and a plotted map of its internal inclusions and surface characteristics. During your face-to-face evaluation at our Houston location, our diamond buyers cross-reference your physical stone under 10x magnification with the specific "fingerprint" detailed on the report to confirm an exact match. If you would like to test or review your paperwork's authentic registration prior to visiting us, you can use the official GIA Report Check Tool to instantly look up your stone's permanent grading metrics archived directly in the GIA laboratory database.
