GIA Certified Marquise Cut Diamonds
When it comes to marquise-cut diamonds, the ratio is everything. But the good news is, there are various ratios that all create a gorgeous-looking diamond – it is entirely personal which one you go for.
A 1:95 ratio is the sweet spot between width and length and is generally considered the most balanced marquise. A 2:15 ratio is perfect for those who want a slim, exaggerated ‘sharp’ shape. A 1:75 creates a curvier shape with a wider body, creating more presence on the finger.
A GIA certificate will outline the color, carat weight, clarity, polish, and symmetry of a marquise diamond. It will also give you the proportions of the diamond so that you can work out the ratios.
