This 1.57ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG771607310 or 771607310. Listed at 17 retailers as of October 29, 2026, with prices from $413 to $3,472, a $3,059 spread on the same certified stone. Brilliant Earth lists it at $3,472. 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.
