About this 1.29ct natural oval diamond

This 1.29ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 6555328018. Listed at 15 retailers as of November 5, 2026, with prices from HK$18,003 to HK$33,442, a HK$15,440 spread on the same certified stone. Helzberg Diamonds lists it at HK$33,442. 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.
