This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407936478 or 407936478. Listed at 12 retailers as of October 29, 2026, with prices from $330 to $1,648, a $1,318 spread on the same certified stone. MOH London lists it at $1,648. 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.
