This 1.51ct lab-grown oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG825655667 or 825655667. Listed at 11 retailers as of November 6, 2026, with prices from HK$2,038 to HK$7,694, a HK$5,657 spread on the same certified stone. Taylor and Hart lists it at HK$7,694. 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.
