Source-derived summary

The DeLong Star Ruby, a 100.32-carat (20.064 g) oval cabochon star ruby. Discovered in Burma in the 1930s, it was sold by Martin Ehrmann to Edith Haggin DeLong for US$21,400, who then donated it to the American Museum of Natural History in New York City in 1937.

History

On October 29, 1964, the DeLong star ruby was one of a number of precious gems stolen in a notorious jewelry heist by Jack Roland Murphy and two accomplices. In January 1965, nine of the stolen gems, including the Star of India and the Midnight Star, were recovered in a bus depot locker; however, the DeLong ruby was not among them. After months of negotiation, the unknown holder of the ruby agreed, through third parties including Dick Pearson, to ransom it for $25,000. The ransom was paid by wealthy Florida businessman John D. MacArthur and he was present on September 2, 1965, when the ruby was recovered at the designated drop off site: a phone booth at a service plaza on the Sunshine State Parkway near Palm Beach, Florida. Months later Dick Pearson was arrested burglarizing a jewelry store in Georgia and was found in possession of $100 bills with serial numbers matching the ransom money. He was convicted and sentenced to 10 years in prison for his involvement in the DeLong Star ruby case.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 100.32-carat star ruby. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 5, 2026. The linked authority identifier is Q1830137. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1937, 1964 and 1965.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
