About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2235725355. Listed at 2 retailers as of October 30, 2026, with prices from $4,686 to $6,224, a $1,538 spread on the same certified stone. Brilliance lists it at $6,224. 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.
