World’s Largest Gemstones
This is a listing of the largest cut gemstones known of these minerals and a spin-off project from another page that is under construction for the world’s largest crystals, this page is continously edited with new information and layout revisions, so this should not yet be considered definitive.
As Peter Rickwood, author of the 1981 publication on the world’s largest minerals, pointed out, defining the largest crystals is not a simple task. After all, what does it mean to be the largest? Largest in size? Largest in volume? Largest in mass? I’ve continued with Rickwood’s idea of defining the largest gemstones with these three categories: size (length), volume, and mass. It is possible that some gemstones may very well be the largest of all three categories. A complication that Rickwood faced was that in some instances, only one or two measurements, such as length and mass, were taken. Unlinke with the largest crystals, many of these gemstones have been cut, polished, and/or faceted, so the other measurements are either unknown and cannot be estimated.

I have am not yet certain of the largest reported crystal of apatite (Ca5(PO4)3(Cl/F/OH)), but a record for a large gemstone apatite is known. Synthetic apatite crystals have been grown (McClure, 2001, p. 57), but I have not found any measurements of the synthetic crystals, so the largest manufactured apatite is unknown.

I have not found much information regarding this gemstone. The largest reported apatite from North America was found in Pulsifer Quarry, Auburn, Maine, USA, which is the same place the Roebling Apatite originated. It was 65.5 carats (0.0131 kg) as an uncut crystal and was cut down to 21.53 carats (0.004306 kg) in 2015 by Dennis Creaser of Creaser Jewelers, Paris, Maine, USA for a private owner.

Beryl (Be3Al2(Si6O18)) is a mineral that comes in a variety of colors and is highly sought after as a gemstone. Varieties of beryl based on color widely known include aquamarine (light blue), bixbite (red), emerald (green), goshenite (colorless), heliodor (yellow), maxixe (dark blue), and morganite (pink). Synthetic beryl crystals have been grown, but I have not found any measurements of the synthetic crystals, so the largest manufactured beryl is unknown.

This aquamarine, known as the Dom Pedro Aquamarine, is the largest cut aquamarine.
From Smithsonian: Mined from a Brazilian pegmatite in the late 1980s, the magnificent aquamarine was named for Brazil’s first two emperors, Dom Pedro Primeiro and his son, Dom Pedro Segundo. Before cutting, the portion of the beryl crystal from which the obelisk-shaped gem was fashioned measured 23.25 inches long and weighed nearly 60 pounds. The obelisk, designed by world-renowned gem artist Bernd Munsteiner, stands 14 inches tall, measures 4 inches across the base and weighs in at 10,363 carats or 4.6 pounds. These impressive dimensions render the Dom Pedro the largest cut-and-polished gem aquamarine known. A pattern of tapering “negative cuts” faceted into the reverse faces of the sea-blue obelisk serves to reflect the light within the gem, giving the piece surprising brightness and sparkle. With the proper lighting, this remarkable sculpture appears to be illuminated from within.

Red beryl (aka bixbite and red emerald) is a small, rare variety of beryl that is best known to occur in the Wah Wah Mountains of Utah, USA. As of 1981, the largest reported faceted red beryl was 2.93 carats (Miley, 1981, p. 405). Additional searching indicates that an 8 carat faceted red beryl is in existance and came from the Ruby Violet claim in the Wah Wahs, which is the most well-known deposit of these minerals. Synthetics are known to be in extistance as well.

This specimen, known as the “Light of the Desert”, the Royal Ontario Museum describes this as:
Cerussite, a lead carbonate mineral, is extremely sensitive to heat and vibration—even warmth from the palm of a hand can damage it. Just imagine how much time and care the gem cutter must have taken to ensure that the inevitable heat generated during polishing and grinding wouldn’t shatter this specimen. The Light of the Desert was so named because of its dispersion (or fire) and for the deserts of Namibia, where it was found, and Arizona, where it was faceted. Dispersion, caused by the splitting of white light into the spectrum of colours, is even greater in cerussite than in a diamond. The Light of the Desert’s sheer size, precision faceting, and lack of inclusions (imperfections in the stone that inhibit the refraction of light) ensure its place as one of the world’s most spectacular gemstones.

This specimen, known as “The Lone Star” was cut in November 1989 and has been entered into the Guiness World Records as the largest star sapphire.
From the Charlotte NC Observer (6 Dec 1989): N.C. Man’s Rock A Star among Gems: By David Perlmutt, Staff Writer: There was nothing remarkable about that morning last June. It was Saturday, long before sunrise. And like most summer Saturdays, Harold Roper had already loaded picks into his Dodge four-wheel pickup truck and driven from his home in Marble deeper into the NC mountains. With him was Rob Cutshaw, his rock-hunting buddy of 25 years. … But on this remarkable morning, Roper made a spectacular find that threatens to make a millionaire out of a man who’s rarely left his native Cherokee Co. Two feet below a vein of earth-where the two had dug for a year and found only chunks of rubies and sapphires-Roper pulled up a deep-blue star sapphire too big to stuff into his pants pocket. Uncut, it weighed 10.5 pounds. Cut and polished, it’s the size of an egg-shaped cantaloupe and weighs 9,719.5 carats. That’s almost nine times larger than the world’s previous largest star sapphire, the “Star of America” weighing 1,154 carats. “Rob threatened to kill me when I found it,” said Roper, 44, who operates a small tool and die plant in Marble, population 500. … Roper’s stone, called “The Lone Star,” was certified last month as a star sapphire by Roger Harding, curator of gems at the British Natural History Museum. Harding recently evaluated the crown jewels of England. Gemnologists in Texas and London estimate the sapphire’s worth in the millions of dollars. They say the color is good, blue with a hint of lavender; the clarity opaque. “It’s a spectacular find,” said Texas gem broker Daniel Banks, who is selling the stone for Roper. “Like a fairy tale that’s come true. Everyone always wants to find a treasure. Mr. Roper has found a treasure. … The stone will go into the next Guinness Book of World Records as the world’s largest cut and polished star sapphire, Banks said. Soon it will hit the road for a year’s tour. … Last week, the stone was put on public display for a day in a Dallas jewelry store. A thousand people showed up. Banks will sell it through sealed bids. He says he already has gotten three inquiries, two from collectors, one from a corporation. Like any boy who digs in the bountiful NC mountain dirt, Roper always dreamed of making such a find. In his teens, he’d go with his late father, Harley, a rock mason, to dig for Indian relics. “My father got me hooked,” Roper said, “He liked relics, I liked gems.” In high school in nearby Andrews, Roper met Cutshaw. After Roper made his big find-at a location they refuse to pinpoint-the two loaded it into a canvas sack and took it back to Roper’s rock room in his 4,000 square-foot brick and cedar house. Curiosity got the best of them and Roper ran the edge of the rough rock over a grinding wheel, deep blue spilled out. So in October, they took it to Dallas and gem cutter John Robinson, who had cut Cutshaw’s sapphire. “We took some other stones with us, but when he saw this one, he grabbed it and didn’t want to see the others,” Roper said. Robinson wanted the stone cut in London and in November he and Banks took it to R. Holt & Co., known for its gem cutting. It took three weeks to cut and polish the stone. Then curator Harding had to pass on it. He told a Dallas newspaper that he knows of no other star sapphire the size of Roper’s stone. They met with Guinness editor Donald McFarlan. Wealth probably won’t change Roper. “I could never leave Marble,” he said. “I have seven men who work for me who depend on a paycheck. I’d probably spend less and less time at the plant and let my son take over. “But I’m not going to dance until I see the money.”

“The Golden Jubilee Diamond” is one of the largest diamonds ever found. Weighing 0.151 kg (755 carats) rough, it was discovered in 1985 at the same mine that produced the Cullinan Diamond (0.62135 kg; 3,106.75 carats), the largest gem-quality diamond found in 1905. The Cullinan was broken into nine pieces, the largest two are now part of the United Kingdom’s Crown Jewels and the other seven are privately owned by Queen Elizabeth II. The Golden Jubilee was cut down to 0.10913 kg (543.67 carats) surpassing the largest of the Cullinan diamonds, the Cullinan I at 0.10604 kg (530.2 carats).
