About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1443970285. Listed at 5 retailers as of October 30, 2026, with prices from $407 to $657, a $250 spread on the same certified stone. 77 Diamonds lists it at $657. 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.
