Margot Robbie’s Engagement Ring: The Understated Pear on Pavé
A celebrity ring at a size real people actually wear — and the one detail on a pear that decides whether it lasts.
Written by the Mapple Gems workshop, Surat · Updated 26 September 2026
Short answer: Margot Robbie’s engagement ring, revealed when she married Tom Ackerley in 2016, is a pear-shaped diamond on a delicate pavé band, most often described in yellow gold. Estimates of the stone vary, with around 1.5 carats the most common. It is one of the most wearable celebrity looks. Our inspired version is a pear moissanite or IGI-certified lab grown diamond on a pavé band, 2 to 5 carats.
Margot Robbie married British producer Tom Ackerley in a small ceremony in Byron Bay, Australia, in December 2016. The news came through a now-deleted Instagram photo showing her ring hand close to the camera. The ring in it was not a showpiece: a pear-shaped diamond held above a fine pavé band, later seen stacked with a thin pavé wedding band.
Reports disagree on the details. Most describe yellow gold and a stone of roughly 1.5 carats; a few say platinum or about three carats. None of it has been confirmed, which is worth remembering whenever you see a precise figure.
Why this is the easiest celebrity look to wear
Most celebrity rings are built around stones of five carats and up. This one is not — which means our 2 carat version is already at or above the size widely reported for the original. A pear also looks larger than its weight: like an oval or marquise, it spreads carats into length. And a thin pavé band keeps the whole ring delicate, so it stacks easily with a wedding band.
The original compared with our inspired version
| Robbie’s ring (as reported) | Mapple Gems inspired version | |
|---|---|---|
| Centre stone | Pear-shaped diamond | Pear moissanite or lab grown diamond |
| Size | Unconfirmed; commonly ~1.5ct | 2, 3, 4 or 5 carats |
| Band | Delicate pavé | Pavé band |
| Metal | Mostly reported as yellow gold | 925 silver or solid 10K/14K/18K yellow, rose or white gold |
| Paperwork | Not public | IGI certificate with lab grown; moissanite is not graded |
Moissanite or lab grown diamond for a pear?
A pear is a brilliant-cut shape, so both materials sparkle strongly. At 2 carats — the size closest to the original — moissanite (dispersion 0.104) shows only moderate coloured fire, because fire grows with stone size; a yellow gold setting calms it further. This is the size where moissanite is at its most convincing. Lab grown diamond (Mohs 10, dispersion 0.044) is chemically diamond and comes with an IGI certificate; like every fancy shape, its report carries no cut grade, so judge the stone on video and look for the bow-tie across its middle.
From the workshop
The point of a pear is the thinnest, most exposed part of the stone and the place it chips if knocked — hardness resists scratches, not impact. When you look at any pear ring, including ours, look at the tip first. You want a V-prong that folds around the point, not a round claw that only touches it. On a delicate pavé band, also ask for the thickness at the base of the shank: pavé removes metal to seat each stone, so a band that looks fine from above can be thin underneath.
Before you order
- Check for a V-prong on the tip.
- Decide which way the point faces — traditionally towards the fingertip.
- Ask for the stone’s length and width in millimetres; about 1.5 to 1.75 reads as a classic pear.
- Ask for the shank thickness under the pavé.
- Order the wedding band with the ring — a pear often needs a contoured band to sit close.
Frequently asked questions
What shape is Margot Robbie’s engagement ring?
It is a pear-shaped diamond on a delicate pavé band, most often described as yellow gold.
How many carats is Margot Robbie’s ring?
It has not been confirmed. Around 1.5 carats is the most common estimate, though some reports suggest larger.
When did Margot Robbie get married?
She married Tom Ackerley in December 2016 in a small ceremony in Byron Bay, Australia.
Are pear engagement rings fragile?
The stone is durable, but its point is thin and can chip if knocked. A V-prong that wraps the point protects it.
Is moissanite a good choice for a pear ring?
Yes, especially around 2 carats, where its extra fire is modest. Moissanite is Mohs 9.25 and suits daily wear, but it is not a diamond and is not laboratory graded.
The pear on pavé look, made to order
