About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded D 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 1538985880. Listed at 24 retailers as of October 26, 2026, with prices from $437 to $1,172, a $734 spread on the same certified stone. MOH London lists it at $1,172. 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.
