About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555372452. Listed at 22 retailers as of October 30, 2026, with prices from HK$38,766 to HK$88,669, a HK$49,903 spread on the same certified stone. NZ Jewellers lists it at HK$88,669. 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.
