A 7 carat marquise ring cannot be judged by its carat number alone. As GIA’s carat-weight guide explains, carats describe weight. The selected stone’s length, width and depth describe its dimensions, while the setting and shoulder diamonds shape the finished ring’s outline. Before choosing a large marquise design, review all three together.
The MISSISSI LUMEN marquise lab-grown diamond ring is a useful example: its approximately 7 ct target refers to the center diamond only. Four tapered baguette lab-grown diamonds sit in two short shoulder channels. Their final weight is confirmed separately.

What does “7 ct” include?
For LUMEN, the number describes the intended center-stone weight, not the combined weight of every diamond in the ring. It is an approximate design target, rather than a promise that a particular 7.00 ct diamond has already been assigned to your order.
Ask for three separate entries in your order confirmation: the selected center’s actual carat weight, the combined accent-diamond weight, and the total diamond weight. This keeps comparisons with other designs meaningful. A ring described by total diamond weight can distribute that weight across many stones, producing a very different appearance from a ring with a single large center.
Request millimeters before deciding how large it will look
Two marquise diamonds of similar weight can have different outlines. Request the selected diamond’s length, width and depth in millimeters. Then review those dimensions against your finger size and the proposed setting, rather than treating a wearing illustration as a ruler.
- Length: How far will the marquise extend along your finger?
- Width: How much space remains for the shoulders on either side?
- Length-to-width relationship: Do you prefer a long, narrow outline or a fuller shape?
- Depth and setting height: How will the stone sit above the finger in the finished construction?
There is no single proportion that makes every marquise right for every hand. Your preferred outline and the specific stone should guide the discussion. Request a neutral-light video of the selected stone as well as its measurements so that you can assess appearance beyond a static rendering.
How baguette shoulders change the design
LUMEN uses four tapered baguette accents, two in each short shoulder channel. The straight lines of these accents provide a geometric transition from the elongated center to the softened flat band. This is a different visual direction from a continuous line of small round pavé diamonds.
When reviewing the design, ask to see how the baguettes meet the center setting, how their spacing looks from above, and where the diamond-set shoulders transition into the plain lower shank. Their final dimensions and weight are confirmed with CAD and stone selection; a preview should not be treated as a stone-by-stone production drawing.
Check the setting from more than one angle
The LUMEN specification calls for two protective V-tips, four lateral claws and a simple open under-gallery, with no hidden halo. A face-up view helps you review the outline. A profile view lets you discuss the height and construction beneath the stone.
Ask how the setting supports the two points, how the claws will be finished, and whether your preferred companion band can sit beside the ring without problematic contact. These are questions for the final design review, not conclusions that can be established from an AI illustration.
A short checklist before approving your order
- Confirm the center diamond’s actual weight, millimeter dimensions and available grading information.
- Confirm the four baguette accents, their dimensions and combined weight.
- Review the top, side and underside CAD views, including tip protection and setting height.
- Record your chosen metal and US ring size, and discuss any companion band you intend to wear.
- Review the final quotation, preparation estimate and applicable shipping and return terms.
Frequently asked questions
Does LUMEN promise an IGI report?
No specific laboratory report is promised by this design listing. Report availability is confirmed for the selected center stone; individual reports are not assumed for small accent diamonds.
Which metals are listed?
LUMEN lists 14K Yellow Gold, 14K White Gold, 18K Yellow Gold, 18K White Gold and Platinum PT950. The gallery illustrates yellow gold with white-colored setting details; confirm the setting-metal treatment for your selected option.
Can a wearing image show the exact scale?
No. The images are illustrative. Use the actual stone measurements, your ring size and the final CAD review to discuss scale and wearing width.
