About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic 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 1547916927. Listed at 14 retailers as of November 6, 2026, with prices from $3,982 to $7,769, a $3,787 spread on the same certified stone. Wholesale Diamonds Direct lists it at $7,769. 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.
