The Story Behind the Stone: The Star of Bombay

The Star of Bombay is a magnificent 182 carat (36.4 g) cabochon-cut dome shaped star sapphire. The violet-blue gem is best known for being given to silent film legend Mary Pickford by her husband, Douglas Fairbanks, Sr.


Its name, Star of Bombay is a blatant and unfortunate re-direct of its actual place of discovery which is Sri Lanka. India has an ancient history with gemstones, still it has never produced a star sapphire that could come close to rivaling the enormous star sapphires discovered in Sri Lanka.

The big deal with natural star sapphires concerns the appearance of very distinct six-rayed stars extending down to the girdle of the stone, when viewed under direct light. The Star of Bombay delivers a wallop in the asterism department. The rays are well developed, rod straight, and extend completely down the side of the stone. That’s a biggie in the star stone world.

What Makes a Star Sapphire?

Rutile needles, referred to as silk, are present in the stone, and account for the ray-like effect. When a crystal contains these natural inclusions, a clever stone cutter orients the stone in such a way as to maximize the effect of the rays by polishing a high domed cabochon onto the stone. The Star of Bombay is celebrated for its remarkably good translucency and a rich violet blue color.
The Star of Bombay sapphire belongs to the mineral species corundum. Pure corundum is colorless, but trace amounts of transition elements like vanadium or chromium result in different colors in the crystal. The Star of Bombay’s violet-blue color is caused by the presence of titanium and iron giving the blue tint, and vanadium contributing to its violet back color.

The famous jewel was acquired by New York jeweler Trabert & Hoeffer, Inc., and was set in a platinum ring and sold to Douglas Fairbanks, Sr., one of the great silent screen icons of the 1920s and 1930s. His equally famous wife, actress Mary Pickford, was called America’s sweetheart.

The Real Deal with Hollywood Jewels

During the early years of American film making, stars often wore their own fabulous jewels in their movies. This was particularly thrilling for audiences when the entire nation fell into the Great Depression. Glimpsing at the stunning jewels provided relief from peoples’ day-to-day drudgery.

And during those years, star sapphires appeared to be wildly popular amongst movie stars. Besides the Star of Bombay there are other instances where star sapphires were used in high profile engagement rings of the period. Douglas Fairbanks, Jr. presented actress Joan Crawford with an engagement ring featuring a whopper-sized 70-carat star sapphire. And actor William Powel proposed to a young platinum haired Jean Harlow with a large star sapphire ring set.


While the Star of Bombay is not hobnobbing in tinsel town any more, grateful gemstone lovers are thankful that Mary Pickford-Fairbanks, Sr., bequeathed her colossal star sapphire to the National Museum of Natural History at the Smithsonian Institution in Washington, DC so that everyone can glimpse at this unique gemstone.
