Origin and design of the Princess Diana aquamarine ring
In 1981, a striking aquamarine ring became closely associated with Princess Diana. The ring features a large oval-cut aquamarine surrounded by 14 baguette and smaller round diamonds, set in 18-carat white gold. Its bold yet elegant design suited both day and evening wear. The center stone is believed to be around 12 carats, though published measurements vary slightly. The overall length is approximately 30–31 mm, with a substantial, attention-grabbing profile. This style reflected the early-1980s taste for dramatic colored stones in high-society jewelry.
Sotheby's 1997 auction and subsequent ownership
Following Diana’s death in 1997, the aquamarine ring was among her jewelry sold at a landmark auction at Sotheby’s in London. It was purchased by a private collector and remained out of the public eye for years. Multiple private owners succeeded after the initial purchase, and the ring changed hands several times before being listed again at auction in the 2000s. Each ownership transition was recorded in auction results, establishing a clear chain of title for researchers and insurers. The ring’s history after 1997 reflects standard practices for high-value celebrity jewelry dispersal.

Physical specifications and valuation
Key measurements and attributes are documented in historic auction catalogues and jewelry reference sources. The oval aquamarine center stone is flanked by baguette diamonds on either side, creating a linear, column-like appearance. The shoulders continue with smaller round brilliant diamonds, adding extra sparkle without overwhelming the central stone. Over time, grading reports for the aquamarine have varied slightly between labs, which is common for colored stones sold at auction. Published value estimates for the ring have generally fallen between £30,000 and £40,000 at the time of the 1997 sale. Inflation and current market conditions for colored-stone jewelry can shift today’s reference values significantly.

Iconic status in royal and celebrity jewelry
Although the ring belonged to Diana in a private capacity rather than as an official royal gift, it became an enduring part of her public image. Its bold size and choice of colored stone aligned with her fashion-forward approach to royal dressing. Media coverage of the 1997 auction and subsequent appearances in exhibition catalogs cemented its status as one of the most recognizable pieces of celebrity jewelry from the late 20th century. The aquamarine’s calm, sea-like color also resonated with the public and has contributed to lasting interest in this particular style.
Identifying features and common comparisons
To distinguish this ring from other aquamarine and colored-stone rings, focus on the following: an oval center stone with step-cut facets, a row of baguette diamonds on each side of the center, and a continuous row of round brilliants along the shoulders. Unlike tiaras or crown jewels, this ring was part of a private collection, so it has no official royal inventory number. It is often compared to other high-profile colored-stone rings from the 1980s, but the 14 baguettes and 14 round brilliants on this piece are distinctive hallmarks when viewed in catalog or auction imagery.
What to know if you’re researching or insuring the ring
For researchers, the most reliable references are Sotheby’s 1997 auction catalogue entries and subsequent hammer price records. Appraisal best practices for similar colored-stone rings include current market rates for untreated aquamarine, gold pricing, and documented provenance. If you are assessing this ring for insurance, obtain a current appraisal from a qualified gemologist, include high-resolution imagery, and document the full ownership chain. As with many celebrity-associated pieces, provenance and condition reports are critical components of valuation and authenticity verification.
