This 1.7ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839611378 or 839611378. Listed at 11 retailers as of October 27, 2026, with prices from HK$2,150 to HK$11,299, a HK$9,149 spread on the same certified stone. Brilliant Earth lists it at HK$11,299. 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.
