About this 0.91ct natural cushion diamond

This 0.91ct natural cushion sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1515181375. Listed at 8 retailers as of October 29, 2026, with prices from HK$13,157 to HK$18,910, a HK$5,752 spread on the same certified stone. GemTrove lists it at HK$18,910. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
