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 6541133078. Listed at 6 retailers as of November 6, 2026, with prices from HK$3,245 to HK$8,229, a HK$4,985 spread on the same certified stone. Do Amore Diamonds lists it at HK$8,229. 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.
