How to Choose the Best 4 Carat Emerald Cut Lab Grown Diamond
Clarity Is The Most Critical Factor at 4 Carats
At 4 carats, clarity is the single most critical factor for an emerald cut diamond — more demanding than at any smaller size. The large open step-cut facets at this legendary size act as dramatically large windows into the stone — making inclusions far more visible than in any brilliant cut diamond of the same carat weight. VVS1 clarity is strongly recommended for a 4 carat emerald cut diamond — Flawless is the ideal choice for the absolute pinnacle of quality at this legendary size. Never compromise on clarity for a 4 carat emerald cut diamond — at this extraordinary size, any visible inclusion significantly and dramatically detracts from the stone's legendary architectural beauty and exceptional value.
Color Is Even More Critical at 4 Carats
At 4 carats, color is dramatically more visible in an emerald cut than at any smaller size — the large open step-cut facets making even the most subtle color tints clearly and immediately perceptible to the naked eye at this legendary size. D color is strongly recommended for white gold or platinum settings at 4 carats to ensure a truly pure, icy, and colorless appearance of legendary beauty worthy of this extraordinary and exceptional size. E color is also an excellent choice offering outstanding value at this legendary size. For yellow or rose gold settings, F color delivers an outstanding result.
Length-to-Width Ratio at 4 Carats
At 4 carats, the length-to-width ratio has an even more dramatic and breathtaking impact on the emerald cut's architectural presence and visual grandeur than at any smaller size. A ratio of 1.40–1.50 produces the most classic and universally flattering emerald cut rectangle at 4 carats — its elongated rectangular form creating a beautifully commanding and architecturally magnificent finger presence of legendary proportion. The most popular and flattering ratio for a 4 carat emerald cut is 1.45 — delivering a beautifully balanced rectangular form of extraordinary architectural elegance and breathtaking visual grandeur at this exceptional and legendary size.
