About this 3.05ct lab-grown cushion diamond

This 3.05ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG658493565 or 658493565. Listed at 14 retailers as of October 30, 2026, with prices from HK$6,747 to HK$38,130, a HK$31,383 spread on the same certified stone. Brilliant Earth lists it at HK$38,130. 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.
