About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555042084. Listed at 15 retailers as of November 6, 2026, with prices from HK$4,969 to HK$11,586, a HK$6,617 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$11,586. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
