About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2497945497. Listed at 16 retailers as of November 6, 2026, with prices from HK$3,934 to HK$12,621, a HK$8,687 spread on the same certified stone. MOH London lists it at HK$12,621. 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.
