About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6241040577. Listed at 23 retailers as of October 30, 2026, with prices from HK$79,771 to HK$151,422, a HK$71,651 spread on the same certified stone. NZ Jewellers lists it at HK$151,422. 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.
