About this 1.83ct lab-grown oval diamond

This 1.83ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1508773443. Listed at 3 retailers as of October 29, 2026, with prices from $1,684 to $2,145, a $461 spread on the same certified stone. GemTrove lists it at $2,145. 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.
