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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1555383416. Listed at 21 retailers as of November 7, 2026, with prices from HK$3,511 to HK$9,247, a HK$5,736 spread on the same certified stone. MOH London lists it at HK$9,247. 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.
