About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556134775. Listed at 15 retailers as of November 5, 2026, with prices from HK$11,231 to HK$36,851, a HK$25,620 spread on the same certified stone. NZ Jewellers lists it at HK$36,851. 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.
