What Is a Moval Diamond? The Marquise-Oval Hybrid, Explained
What a Moval Is
A moval is a hybrid of two classic shapes, the marquise and the oval. It is an elongated diamond with the soft, rounded sides of an oval and the gently tapered, lightly pointed ends of a marquise. The name is just those two words combined: marquise plus oval. It is a modern trade name, not an officially recognized gemological shape, so a grading report describes its geometry rather than printing the word "moval."
Like other elongated shapes, a moval faces up large for its carat weight and lengthens the line of the finger. Here is what it is, who it tends to suit, and what to check before you buy.
The shape, defined
Start with the outline. A moval reads as an elongated oval whose two ends draw in to soft points, sitting visually between a true oval (fully rounded ends) and a marquise (sharp, pronounced points). The sides keep the gentle curve of an oval, so the overall effect is elongated and modern without the drama of a full marquise. It is usually cut in a brilliant style, like its oval and marquise parents, for lively sparkle.
Because "moval" is a trade name rather than an official category, you will not see it printed on a GIA, IGI, or GCAL report; the lab describes the measurable geometry instead. It is one of the distinctive elongated shapes we offer, alongside our signature Dutch Marquise, and we hand-set and finish these in NYC.
Moval vs oval vs marquise
All three are elongated brilliant shapes. The difference is in the ends.
| Oval | Marquise | Moval | |
| Ends | Fully rounded | Sharp points | Softly pointed |
| Sides | Curved | Curved to a point | Curved, oval-like |
| Reads as | Soft, classic | Dramatic, pointed | Elongated and modern, between the two |
| Face-up size | All elongated, so all face up larger than a round of the same carat weight | ||
Who a moval suits
A moval tends to suit someone who loves the elongated look but finds a marquise's sharp points too dramatic and a plain oval too common. It reads modern and a little unexpected, which is the appeal for a buyer who does not want the same ring as everyone else. Like all elongated shapes it lengthens the finger and looks larger for its carat weight, so it makes a confident center stone without needing extra size.
What to verify before you buy
A moval is a specialty shape, so a few checks matter more than usual:
Most fancy shapes carry no overall cut grade from the labs, so cut quality varies. Look at the actual stone and its proportions, not just the name.
"Moval," like most trade names, may not appear on the report. Labs describe the measurable geometry, so read the measurements rather than trusting the label.
Watch the bow-tie. Elongated brilliant shapes can show a dark band across the center; favor a faint one over a heavy one.
Confirm the report (GIA, IGI, or GCAL) on the lab's own site, and check for the "LG" inscription if it is a Lab Grown Diamond.
The rule that covers all of it: a name is marketing, the report is fact.

FAQ's
A moval is a hybrid of the marquise and the oval: an elongated diamond with an oval's curved sides and gently pointed ends. The name combines "marquise" and "oval." It is a trade name, not an officially recognized gemological shape, so the report describes its geometry.
No. An oval has fully rounded ends, while a moval draws those ends in to soft points. The moval reads a little more elongated and distinctive, sitting between an oval and a marquise.
A marquise has sharp, pronounced points and sides that curve to those points. A moval softens the points and keeps the gentler curve of an oval, so it looks elongated and modern without the full drama of a marquise.
Usually, for the same carat weight. Like other elongated shapes, a moval spreads its weight across a longer face-up area, so it tends to look larger than a round of the same carat and lengthens the finger.
Often not. Labs certify measurable geometry, not trade names, so the report describes the shape rather than printing "moval." Read the measurements and confirm the report number on the lab's own site.
Yes. A moval is a shape, not an origin, so it is available as a Lab Grown Diamond. Note the grading difference: since October 1, 2025, GIA grades Lab Grown Diamonds on Premium and Standard descriptive tiers, while IGI and GCAL still issue full 4C-style reports (Source: GIA, 2025-10-01). The cut is about the outline; confirm both the shape and the grades on the report.
