This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778617177 or 778617177. Listed at 21 retailers as of October 29, 2026, with prices from $257 to $2,212, a $1,955 spread on the same certified stone. Do Amore Diamonds lists it at $2,212. 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.
