We look past the grading report.
Most buyers are new to diamonds, so we show you everything. Every stone we sell or source for you is examined in our own lab.
01
Structural inspection
Checked for surface-breaching inclusions that could compromise the diamond's integrity.
02
Color & growth review
Screened for brown or blue hues in HPHT diamonds and for internal graining and stria in CVD diamonds.
03
Light performance
Evaluated with the same technologies used by the AGS and GIA labs.
