About this 0.51ct lab-grown radiant diamond

This 0.51ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG729572044 or 729572044. Listed at 5 retailers as of November 4, 2026, with prices from HK$1,428 to HK$4,331, a HK$2,903 spread on the same certified stone. Michael Trio lists it at HK$4,331. 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.
