About this 4.02ct natural oval diamond

This 4.02ct natural oval sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231795318. Listed at 10 retailers as of October 31, 2026, with prices from HK$314,440 to HK$548,949, a HK$234,509 spread on the same certified stone. MOH London lists it at HK$548,949. 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.
