About this 3.51ct natural oval diamond

This 3.51ct natural oval sits in the three to five 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 2566188483. Listed at 4 retailers as of October 29, 2026, with prices from HK$442,701 to HK$781,828, a HK$339,127 spread on the same certified stone. MOH London lists it at HK$781,828. 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.
