Buying Guide: Cushion Cut Lab Grown Diamonds
What to consider when choosing cushion cut diamonds
Look at carat weight in relation to cut depth and table width. Cushion cuts can appear larger or smaller than other shapes at the same carat due to their facets. Prioritize IGI or GIA-equivalent certification to verify authenticity and grading accuracy.
Color and clarity balance
For cushion cuts, color differences are more noticeable in larger stones. Aim for near-colorless grades (D-F or E-F) to preserve warmth and fire, especially in 2.5–3.0 carat cushions.
Setting style and proportion
Four-prong solitaires maximize brilliance, while halos enhance perceived size. Halo designs work well with cushion shapes to offset color or clarity considerations in larger stones.
Lab-grown versus mined
Lab-grown diamonds offer ethical advantages and typically lower cost per carat with identical chemical composition to mined stones. Consider your environmental goals, budget, and desired story when choosing.
Practical sizing and proportions
Always review the scale image and dimension details. Larger stones may require proportionate ring settings to avoid top-heavy or unbalanced designs.
Care and durability tips
Maintain resilience by selecting appropriate hardness and mounting for daily wear. Cushions are durable but benefit from sturdy settings to protect against bending and edge chipping.
