About this 0.91ct natural oval diamond

This 0.91ct natural oval sits in the just-under-one-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 6525253423. Listed at 13 retailers, with prices from $2,159 to $4,632 at NZ Jewellers, a $2,473 spread on the same certified stone. 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.
