About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552262434. Listed at 12 retailers as of October 26, 2026, with prices from HK$43,515 to HK$81,321, a HK$37,806 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$81,321. 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.
