This 0.51ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG649440284 or 649440284. Listed at 2 retailers as of October 29, 2026, with prices from HK$3,358 to HK$4,341, a HK$982 spread on the same certified stone. Diamond Quarter lists it at HK$4,341. 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.
