The Sapphire Ring That Changed Jewellery Forever
In 1981, Lady Diana Spencer chose a ring from Garrard's catalogue that broke every rule of royal engagement tradition. The 12-carat oval Ceylon sapphire, surrounded by 14 round brilliant-cut diamonds and set in 18-carat white gold, was not custom-made for a princess — it was available for anyone to buy. That decision, and the ring's journey from Diana's finger to Kate Middleton's, transformed the sapphire engagement ring from a historical curiosity into the most recognised alternative to a diamond solitaire.
What Exactly Is Princess Diana's Sapphire Ring?
The ring is a 12-carat oval Ceylon sapphire surrounded by 14 round brilliant-cut solitaire diamonds in a cluster setting, made in 18-carat white gold by Garrard. The firm confirms on their own website: "At the centre of the cluster engagement ring is a Ceylon sapphire of singular beauty, surrounded by 14 solitaire diamonds." Sotheby's independently confirms the stone's Ceylon (Sri Lankan) origin.
The ring's original cost is contested — sources cite figures ranging from approximately £28,000 to £47,000 — but no primary Garrard documentation has been published to confirm a precise price.
| Detail | Specification |

| Centre stone | 12-carat oval Ceylon sapphire |
| Surrounding stones | 14 round brilliant-cut diamonds |
| Metal | 18-carat white gold |
| Maker | Garrard (Crown Jewellers) |
| Year | 1981 |
| Original price | Approximately £28,000–£47,000 (contested) |
Why Was Choosing from a Catalogue So Revolutionary?
Diana selected her engagement ring from Garrard's existing catalogue rather than commissioning a bespoke piece — a departure from royal tradition that drew criticism at the time. Prior royal engagement rings were private commissions: Prince Philip used diamonds from Princess Alice of Battenberg's tiara when he designed Queen Elizabeth's ring in 1947.
Diana's choice meant that anyone could walk into Garrard and order the same ring. The Queen was reportedly unhappy with this arrangement. But the decision reflected something deliberate — Queensmith describes it as "a bold move that helped redefine what a royal engagement ring could be." It democratised royal jewellery in a way that no bespoke commission could have.
How Did the Ring Pass to Kate Middleton?
Prince William proposed to Catherine Middleton in Kenya in October 2010 using his mother's sapphire ring. In the ITV engagement interview broadcast on 16 November 2010, William explained: "It's my mother's engagement ring. Obviously she's not going to be around to share any of the fun and excitement of it all — this was my way of keeping her sort of close to it all."
The ring's second life amplified its influence. A new generation of buyers saw the sapphire cluster design on global television, and interest in sapphire engagement rings — both new and antique — surged.

Were Sapphires Traditional for Engagement Rings Before Diana?
Sapphires were a standard engagement stone long before 1981. Victorian and Edwardian jewellers set sapphires in engagement rings alongside diamonds, rubies, and emeralds. The sapphire symbolised fidelity, constancy, and wisdom — qualities considered essential for marriage. Queen Victoria herself received a sapphire and diamond brooch from Prince Albert the day before their 1840 wedding, establishing a royal precedent for sapphires in bridal jewellery.
Sapphire Sources Through History
The finest sapphires came from three historic sources, each producing stones with distinctive characteristics:
| Source | Period of Peak Production | Distinctive Quality |
|---|---|---|
| Ceylon (Sri Lanka) | Continuous since antiquity | Bright, medium blue; excellent transparency |
| Kashmir | 1881–1930s (now effectively exhausted) | Velvety, cornflower blue; extremely rare |
| Burma (Myanmar) | 19th–20th century | Deep, royal blue; often vivid saturation |
Diana's stone was a Ceylon sapphire — the most widely available of the three historic sources and the origin of many sapphires found in antique rings today. For a comprehensive guide to sapphire origins, cuts, and characteristics, see Sapphires in Antique Rings.
What Types of Antique Sapphire Rings Can You Find?
Antique sapphire rings span every era and design style. Georgian sapphire cluster rings featured central stones surrounded by smaller diamonds — the same arrangement, in essence, that Diana's ring used two centuries later. Victorian sapphires appeared in three-stone settings alongside diamonds, in half-hoop designs with graduated stones, and in sweetheart rings combining sapphires with heart motifs. Edwardian jewellers set sapphires in platinum and millegrain settings of extraordinary delicacy.
The "Diana effect" is real for collectors: sapphire rings from the Victorian and Edwardian periods attract strong demand from buyers who want the sapphire-and-diamond combination with the character and craftsmanship of an earlier era. A Victorian sapphire cluster ring offers a historical connection that a modern reproduction cannot match.

How Should You Choose a Sapphire Engagement Ring?
For buyers drawn to the sapphire engagement tradition, antique sapphires offer advantages over modern stones. Antique Ceylon sapphires were cut to maximise colour and fire rather than carat weight, producing stones with distinctive warmth that modern precision-cut sapphires often lack. Old-cut stones also tend to show more play of light in candlelit or low-light settings — the conditions under which they were designed to be seen.
Key considerations when buying an antique sapphire ring:
- Colour — look for an even, saturated blue without dark patches or strong green undertones
- Origin — Ceylon sapphires are the most common in antique rings; Kashmir sapphires are the rarest and most valuable
- Setting — check that the sapphire is secure in its setting, as antique collet mounts can loosen over centuries
- Treatment — many modern sapphires are heat-treated to improve colour; unheated antique sapphires carry a premium

Frequently Asked Questions
What is Princess Diana's engagement ring made of?
The ring is a 12-carat oval Ceylon sapphire surrounded by 14 round brilliant-cut diamonds, set in 18-carat white gold. It was made by Garrard, the Crown Jewellers. Diana selected it from Garrard's existing catalogue in 1981 rather than having it custom-made — a break from royal tradition.
Why was Diana's ring controversial?
Diana chose her ring from Garrard's retail catalogue, meaning anyone could order the same design. Previous royal engagement rings were bespoke commissions. The Queen was reportedly unhappy with the arrangement, but the choice democratised royal jewellery and helped redefine what a royal engagement ring could be.
Does Kate Middleton wear the same ring?
Prince William proposed to Catherine Middleton in Kenya in October 2010 using Diana's original sapphire ring. William said in the engagement interview: "It's my mother's engagement ring... this was my way of keeping her sort of close to it all." The engagement was publicly announced on 16 November 2010.
Were sapphire engagement rings popular before Diana?
Sapphires were a standard engagement stone throughout the Victorian and Edwardian periods, symbolising fidelity, constancy, and wisdom. Queen Victoria received a sapphire brooch from Prince Albert the day before their 1840 wedding. Diana's choice revived a tradition that had been overshadowed by the twentieth-century diamond marketing campaigns.
Where did Diana's sapphire come from?
The sapphire is of Ceylon (Sri Lankan) origin, confirmed by both Garrard and Sotheby's. Ceylon has produced sapphires since antiquity and is the source of many sapphires found in antique rings. Kashmir sapphires are rarer and more valuable, but Ceylon stones are prized for their bright, transparent blue.
How much did Diana's ring originally cost?
The original price is contested — sources cite figures ranging from approximately £28,000 to £47,000. No primary Garrard documentation has been published to confirm a precise price. The ring's current value, given its provenance, is incalculable.
