About this 1.3ct natural oval diamond

This 1.3ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6515509310. Listed at 21 retailers as of November 2, 2026, with prices from HK$22,470 to HK$50,669, a HK$28,199 spread on the same certified stone. NZ Jewellers lists it at HK$50,669. 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.
