This 1.9ct 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 LG847632631 or 847632631. Listed at 11 retailers as of October 31, 2026, with prices from $578 to $2,851, a $2,273 spread on the same certified stone. Brilliant Earth lists it at $2,851. 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.
