What are star rubies?
Star rubies are a rare variety of gemstone rubies. These magnificent gemstones display a six ray star which appears to magically glide and sparkle across the surface of the gem when it is moved. This is due to an optical phenomenon called “AsterismThe star is best seen when the ruby star is seen in a single light source such as sunlight and spotlights.
What causes the star effect?
Star effect or “asterism“is caused by the dense inclusions of tiny fibers of rutile (also known as “silkStars are caused by light reflected from needle-shaped inclusions of rutile aligned perpendicular to the star’s rays. However, since rutile is always present in star rubies, they are never completely transparent. In fact, the star ruby is one of those rare gemstones which actually require inclusions (ie rutile).
Are star rubies rare?
Today, out of 100 rough corundum (ruby and sapphire) extracted; only three will have visible stars after being cut into cabochons. Of these three, one will have a bad color but a good star; we will have a bad star but a good color and only one in a hundred will have both a lucky star and a good color!
Most of the original sources of star rubies such as Mogok (Burma) have run out of supplies. Today’s global production produces a very small amount of fine stars (especially in sizes over 5 carats). Star rubies are increasingly rare as most of the rough stones today are cut into faceted stones after heating instead of being cut into cabochons to display the star.

Famous Star Rubies:
Delong’s Star Ruby resides at the Natural History Museum in New York. It weighs 100.32 carats. Discovered in Burma at the beginning of the 20th century, it was sold by Martin Ehrmann to Edith Haggin DeLong, who donated it to the museum. In 1964, the Delong Star Ruby was the subject of an infamous heist, carried out by Jack Murphy, known as Murph the Surf, and two other men. It was then redeemed and recovered. The Delong Star was found at a designated drop-off site – a telephone booth in Florida.
The Ruby Rosser Reeves is one of the largest and thinnest star rubies in the world. Weighing 138.7 carats, it is not only clearer and more translucent than the Star of Delong, but also has a sharp six-rayed star. This Sri Lankan stone is renowned for its beautiful color and well-defined star pattern. Advertising mogul Rosser Reeves, who donated the piece to the Smithsonian in 1965, carried her like a lucky stone, calling her her baby. He has often stated that he acquired the stone at an auction in Istanbul in the mid-1950s. He actually bought the stone from Robert C. Nelson Jr. of New York who was acting on behalf of Firestone & Boston Parson. Firestone & Parson sold the stone for Mr. Paul Fisher of New York. Mr. Robert Fisher, Paul’s father, had bought the ruby at an auction in London in 1953. At the time, the ruby then weighed just over 140 carats, but was heavily scratched, and a few carats. were removed during repolishing. The repolishing also helped to center the star of the stone. Articles in the New York World-Telegram and the Sun in 1953 mentioned this fabulous gemstone.

What to look for when buying a Star Ruby:
The value of star rubies is mainly influenced by two things: (a) The strength and sharpness of the star, (b) The intensity and attractiveness of the body color.
Star sharpness: The star should be sharp and silvery / milky white. The best way to test the star’s sharpness is to look at the ruby star in the sun with the dome facing the sun. All six pins should be straight and equally prominent. The full star should be centered in the middle of the gem, but should also be able to slide effortlessly around the cabochon.
Gemstone Color: Rubies are generally red. But the star ruby is generally not red. Most star rubies are available in pinkish red, purplish red, or purplish brown. Red rubies with a perfect star are very, very rare and can cost a fortune.
Chopped off: The cut is very important to show the star effect of the ruby. They should be cut into medium to high domed cabochons to achieve the perfect star effect. Cabochons must be round or oval. The stone should not be too flat at the top nor too heavy at the bottom. Many star backgrounds are not polished so that the light is trapped inside the gemstone.
Caring for your star ruby:
Although there are very few chemicals that attack Star Rubies, it is best to clean your Star Ruby with warm soapy water and a toothbrush. It is not recommended to clean your Star Ruby in ultrasonic cleaners.
Treatments and synthetics:
True star rubies are usually not heat treated because heating can dissolve the rutile (silk) that causes the star to form in the first place.
Beware of synthetic star rubies (laboratory-made)! Synthetic star rubies look too perfect i.e. perfect star, super clean stone and beautiful color. In natural star rubies, the color distribution is often uneven, in streaks and spots – which is the best way to judge with the naked eye whether the star ruby is natural or synthetic. However, sometimes it can be difficult to distinguish between natural and synthetic gemstones and if you come across such a stone, be sure to request a reputable gemstone lab certificate from the seller. There is no doubt that synthetic star rubies are much cheaper than natural rubies, but they can offer little or no resale value.
Tips on Star Ruby jewelry:
Star rubies are available in all forms of jewelry. However, Star Ruby rings and pendants are generally preferred. To maximize its astrological and healing effects, it is advisable to mount the gemstone in the jewelry so that the bottom of the stone touches the skin. Star Ruby can also be stored as a loose gemstone. Rubies look best in yellow gold jewelry, although it really depends on the wearer’s choice.
To conclude, if you are looking for a gemstone, but don’t know which one to buy, look no further – get this mystical gem!
