About this 1.85ct lab-grown oval diamond

This 1.85ct 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 stated by the retailer rather than the lab and certified by GIA 1508901779. Listed at 2 retailers as of November 1, 2026, with prices from $1,096 to $3,216, a $2,121 spread on the same certified stone. MOH London lists it at $3,216. 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.
