Diamond Pricing / 4 min read
What Affects the Price of a 1ct Lab-Grown Diamond?
Many buyers start with 1ct pricing, but diamonds of the same carat can vary significantly by specification and visual quality.
Carat is not everything
Carat is weight, not the entire face-up size. Two 1ct diamonds can look different on the hand.
Oval and pear shapes often appear elongated, while round diamonds offer classic brilliance.
Color, clarity, and cut
D-F colors feel bright and icy, while G-H can be balanced depending on setting and preference.
Clarity should be considered by shape. Emerald cuts often need more clarity attention.
Certificate and consultation
IGI certification helps compare stones, but real imagery and consultation also matter.
LUX GEM helps compare stones against ring design, budget, and timeline.
