This 1.71ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634489 or 840634489. Listed at 13 retailers as of October 28, 2026, with prices from $419 to $4,330, a $3,911 spread on the same certified stone. Rare Carat lists it at $4,330. 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.
