About this 1.31ct natural oval diamond

This 1.31ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7526737417. Listed at 17 retailers as of October 30, 2026, with prices from HK$18,779 to HK$42,508, a HK$23,729 spread on the same certified stone. NZ Jewellers lists it at HK$42,508. 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.
