About this 1.25ct lab-grown radiant diamond

This 1.25ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG681504549 or 681504549. Listed at 16 retailers as of November 4, 2026, with prices from HK$1,200 to HK$7,772, a HK$6,572 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$7,772. 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.
