About this 4.03ct natural cushion diamond

This 4.03ct natural cushion sits in the three to five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545894612. Listed at 9 retailers as of November 2, 2026, with prices from HK$243,594 to HK$397,045, a HK$153,451 spread on the same certified stone. MOH London lists it at HK$397,045. 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.
