Square emerald cut lab diamonds vary in how their corners are trimmed, with more heavily cropped corners creating an almost octagonal outline and more subtly trimmed corners keeping the silhouette closer to a true square shape. The number of step facets on the crown and pavilion also varies slightly between cutters, affecting how the light travels across the stone’s surface and how bold the resulting flashes appear.
Achieving a truly square emerald cut, rather than a slightly rectangular one, demands exacting proportion work from the cutter, since even a small deviation throws off the symmetry that makes this shape so distinctive. That precision, along with carat weight and clarity, plays the biggest role in determining the cost of a lab grown diamond cut this way, more so than with many other fancy shapes.
Because step facets expose inclusions more readily than brilliant faceting does, clarity carries extra weight when selecting a square emerald stone. We recommend viewing clarity closely before finalizing any lab grown diamond of this shape, paying particular attention to inclusions near the center of the table.
A square emerald lab grown diamond pairs naturally with a similarly geometric setting, such as a bezel or a simple four-prong mount, since ornate or curved settings can visually clash with the shape’s crisp, architectural lines. Buyers aiming for a cohesive, modern look tend to keep every design element around the stone equally clean and geometric.
Depth percentage plays a larger role in this shape’s brilliance than it might for a more elongated emerald cut, since a square proportion leaves less room for light to travel before reflecting back to the eye. A well-proportioned cutter accounts for this carefully when shaping a square emerald lab created diamond from the rough.
If you already have a carat weight and clarity grade in mind, or you’d simply like our team’s guidance on what suits your design best, Loose Grown Diamond is glad to help with either approach. Reach out with a reference image or a written description of your vision, and we’ll begin the process of finding or creating a square emerald lab created diamond that matches it.
A square emerald lab diamond has the same long, flat step facets as an emerald cut, just set inside an even, square shape instead of a long one. That gives it a calm, tidy look with wide, clear flashes of light.
The open facets on this square emerald lab grown diamond let small flaws show more easily than on other cuts. A VS2 grade or higher usually keeps the stone looking clear at first glance.
