About this 0.3ct natural oval diamond

This 0.3ct natural oval sits in the sub-half-carat band, graded G 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 1558899050. Listed at 15 retailers as of November 1, 2026, with prices from $508 to $1,230, a $722 spread on the same certified stone. MOH London lists it at $1,230. 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.
