Behind the piece
The Georgina Oval-Cut Diamond Solitaire Ring – Lab-Grown | 18K Gold or Platinum
Every Una ring begins with a clear point of view and a commitment to craft. Yours is no exception.
The Georgina is a single oval-cut lab-grown diamond in a slim four-prong solitaire setting — the engagement ring that has become the defining look of this decade. The oval shape flatters every hand type, elongating the finger and appearing larger face-up than a round diamond of the same carat weight. Understated but with presence. Made by hand to order in solid 18K gold or platinum.
Set with an IGI certified lab-grown oval diamond, The Georgina is a lab-grown solitaire engagement ring at its most refined. A lab-grown diamond is chemically, physically and optically identical to a mined diamond — the only difference is origin. Every stone comes with a full IGI grading report covering cut, colour, clarity and carat weight.

Why oval?
The oval cut is the most universally flattering diamond shape. Its elongated brilliant facets produce the same level of sparkle as a round brilliant, and its curved form is gentle and feminine without being fussy. Paired with a slim band in 18K yellow gold or platinum, The Georgina is a ring that will look exactly right in thirty years. From $6,100 AUD.
Why oval? The case for the decade's most popular engagement ring shape
The oval cut has dominated engagement ring searches for several years running, and not without reason. The elongated shape creates the optical effect of longer, slimmer fingers regardless of hand type. It also returns exceptional face-up size — an oval-cut diamond at a given carat weight typically appears 10–15% larger than a round diamond of the same weight. If maximising visible stone size matters to you, the oval delivers more of it per dollar spent. The Georgina sets all of this in a slim four-prong solitaire — the simplest setting there is, and the best way to let the stone speak for itself.
Lab-grown oval diamonds: what to look for
Oval lab-grown diamonds can show a phenomenon known as the "bowtie effect" — a shadow across the centre of the stone caused by the way the facets are arranged. The severity varies significantly between stones. At Una Diamond, we hand-select oval lab-grown diamonds that minimise the bowtie and maximise brilliance. Every stone comes with an IGI certificate. Browse our full range of oval engagement rings, solitaire diamond rings, and 18K white gold and platinum options.
