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 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 1547300573. Listed at 9 retailers as of October 30, 2026, with prices from HK$30,088 to HK$54,951, a HK$24,863 spread on the same certified stone. NZ Jewellers lists it at HK$54,951. 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.
