Lab Grown Marquise Diamond Rings
An elongated shape does something a round stone can't — it makes a diamond look bigger than its carat weight, and a finger look longer than it is. That's the whole appeal of our lab grown marquise diamond rings, and why the cut keeps finding its way back into style every few seasons instead of fading out. Pointed at both ends and curved along the sides, the marquise shape spreads its surface area wide, which is exactly what gives it that stretched, eye-catching sparkle a round or cushion stone can't match.
Every centre stone here is a certified lab grown diamond, graded on cut, colour, clarity, and carat the same way a mined stone would be, just grown under controlled heat and pressure instead of underground. That process is what makes the value work in your favour, letting you choose a larger marquise diamond or a cleaner clarity grade without stretching your budget to match.
Shop solitaire, hidden halo, side stone, and statement settings, each hand-finished in 18K white, yellow, or rose gold. Whichever setting you choose, the marquise cut's elongated silhouette stays the focal point, built to catch light from nearly every angle it's turned toward.
Shop Marquise Diamond RingsMarquise Ring Styles, Compared
The setting changes how much a marquise diamond ring sparkles and how it sits day to day, more than most buyers expect going in. Here's how the four settings in this collection actually differ once worn, not just described.
| Setting | Signature Look | Best For |
|---|---|---|
| Solitaire Marquise | A single marquise diamond, unaccompanied, letting its elongated shape and brilliance stand on their own. | Buyers who want the stone's silhouette to speak for itself. |
| Hidden Halo Marquise | A ring of pavé diamonds set beneath the centre stone, boosting brilliance while keeping the top profile clean. | Anyone who wants extra sparkle without a visibly busier setting. |
| Side Stone Marquise | Smaller diamonds set along the band beside the centre stone, framing its length with continuous shine. | Buyers who want the band itself to carry visible detail. |
| Statement Marquise | A bolder build with a larger centre stone or architectural setting designed to draw the eye first. | Anyone who wants the ring itself to be noticed first. |
Still deciding? Hidden halo and side stone marquise engagement rings are the easiest middle ground — both add brilliance around the centre stone without changing how the ring reads on the hand day to day.
Three Decisions, In the Right Order
Shopping for a marquise diamond ring gets easier once you stop trying to decide everything at once. These three choices happen in sequence, and each one narrows down the next.
Length-to-Width Ratio
A ratio near 2:1 is the most classically proportioned marquise cut — elongating the finger without looking too narrow or too stubby.
Setting Style
Solitaire, hidden halo, side stone, or statement — decide based on how much sparkle and detail you want around the centre diamond.
Gold Tone & Sizing
Match the metal to jewellery already worn daily, then confirm ring size — a pointed marquise sits differently on the hand than a round stone does.
18K White, Yellow & Rose Gold
Every lab grown marquise diamond ring in this collection comes in three 18K gold finishes. The diamond and setting stay identical across all three — only the tone changes, and that tone changes how the elongated shape reads against the skin.
White Gold Marquise Rings
A cool, rhodium-plated finish that sharpens contrast against the diamond, making the pointed ends of the marquise cut stand out most clearly.
Yellow Gold Marquise Rings
A warm, traditional tone that softens the marquise silhouette slightly, giving it a more vintage, heirloom-leaning character.
Rose Gold Marquise Rings
A romantic blush finish from added copper content, which also makes it the most scratch-resistant of the three metals for daily wear.
