I’ve been researching background for another story featuring my character Jerry Milam, a World War II veteran and ex-cop turned PI. In looking for crimes for my detective to solve, I started digging into old newspapers for information on jewel thefts. I chose the topic because I’d read about the robbery of the American Museum of Natural History in New York in 1964. While the robbers were later caught, only ten of the twenty-four stolen gems were recovered. In researching that theft, I discovered that the Witte Museum in San Antonio was robbed in 1969, with a thief smashing a glass display case in order to snatch the forty-nine carat McFarlin Diamond, a canary yellow, emerald cut stone described as being the size of a hen’s egg, which was also never recovered.
Then, I fell down the rabbit hole.
Back in the days when J. Edgar Hoover was still in charge of the FBI, jewel thefts were all the rage in crime. Jewels, once removed from their settings, were impossible to identify because, unlike today, they had no microscopic serial numbers etched on them. Etching of jewels for identification purposes began in 1983. While watches had serial numbers, most people didn’t bother to make a note of theirs. Fences were happy to purchase stolen jewels and watches because they were so hard to link back to the original owners. Most gem stones were easily recut or reset and resold, vanishing forever.
Most jewel robberies in the 1950s and 1960s were committed by stealth, leading to the image of the lithe cat burglar crawling over rooftops firing the popular imagination. Alfred Hitchcock even made the movie To Catch a Thief, released in 1955, with Cary Grant playing a retired jewel thief known as the Cat.
Between 1959 and 1967, Lauren Bacall, Winston Churchill, Sophia Loren, Eva Gabor, and Yul Brenner, along with other famous and wealthy people, were relieved of their jewels by thieves. With the exception of Eva Gabor, none were present at the time of the theft. Thieves, likely the same ones who robbed the American Museum of Natural History’s gemological exhibit a few months later, waited for Eva Gabor and her husband to return to their hotel room in order to steal her twenty-five-thousand-dollar diamond ring, which they had been unable to locate while she was away from the room. They pistol whipped and bound Ms. Gabor and forced her husband to retrieve the ring from the hotel safe before making their getaway.
If you are wondering why one ring was enough for the thieves to risk adding armed robbery and kidnapping to the charges against them, consider that the average income in 1965 was less than seven thousand dollars a year. A twenty-five-thousand-dollar ring was worth several years income to most people.
My research led me to realize that even without serial numbers and etched identification codes, certain jewels would be easier to trace than others. Which jewels might be more traceable? Cabochon star rubies and sapphires. A rounded, polished shape, called a cabochon, was how all jewels were prepared before cutting was developed for gemstones. Opals are still prepared and set as cabochons.
Star rubies and star sapphires exhibit a phenomenon called asterism, a star pattern visible when light hits the stone. The star is created by long inclusions inside the stone. Stones with asterism are rounded and polished as cabochons, not cut, to preserve the star within them.

Star rubies and star sapphires are valued based on the clarity and size of their stars, the color saturation and transparency of the stone, by their shape, and by their inclusions and cloudy areas. These same features make the stones more easily traceable and identifiable. While other gems can be recut and reset to disguise them, star rubies and star sapphires can’t be cut because the rounded shape is what allows the star to be seen.
Is it any surprise that the most valuable stones recovered from the American Museum of Natural History robbery were the Star of India, one of the largest blue star sapphires in the world, and the DeLong Star Ruby, while the Eagle Diamond was never found?
That’s enough rantings from the rabbit hole.
