About this 5.51ct natural cushion diamond

This 5.51ct natural cushion sits in the over five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 7553304343. Listed at 14 retailers as of October 24, 2026, with prices from $164,321 to $316,651, a $152,330 spread on the same certified stone. Helzberg Diamonds lists it at $316,651. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
