Ruby is the birthstone for July and the gem for the 15th and 40th anniversaries. On May 12, , a There are a number of processes used to alter the color, apparent clarity, or improve the durability of gems.

Some gemstones have synthetic counterparts that have essentially the same chemical, physical, and optical properties, but are grown by man in a laboratory.

Any gem can be imitated—sometimes by manmade materials or by natural materials chosen by man to impersonate a particular gem. Fine ruby glows with intense red in sunlight thanks to red fluorescence, which intensifies its red color.

The first laser was created in using the red fluorescence light emitted by ruby. Baby Shark. Chilling Adventures of Sabrina.

Black Lightning. The Curse of La Llorona. Rise of the Teenage Mutant Ninja Turtles. Jojo Siwa. Ghostbuster's 35th Anniversary. Men in Black: International.

Ruby is also pleochroic , and will sometimes display a lighter and more intense color when viewed at different angles.

Ruby is a tough and durable gem, and the only natural gemstone harder than Ruby is Diamond. Despite this, Ruby is still subject to chipping and fracture if handled roughly, and care should be taken to ensure it is properly handled.

Ruby was first synthesized in The process of creating synthetic Ruby is known as the Verneuil process.

Only experts can distinguish between natural and synthetic, lab-created Ruby. Ruby is one of the most popular gemstones, and is used extensively in Jewelry.

Ruby is used in all forms of jewelry, including bracelets, necklaces, rings, and earrings. It is used both as centerpiece gemstone in pendants and rings, as well as a secondary stone to complement other gemstones such as Diamond s.

Star Ruby is polished as cabochon s, and, if clear, can be extremely valuable. Large Ruby gems are extremely rare and valuable. Fine colored Ruby with a deep red color and excellent transparency can reach several thousand dollars a carat.

Synthetic Rubies are inexpensive and often used as a cheap substitute for natural rubies. Ruby is the birthstone for July. We recommend buying only from a trusted ruby jewelry vendor such as James Allen to avoid buying fake rubies.

To tell a fake ruby from a real one, you can use the following techniques:. Note that a lab-created ruby is not the same as a fake ruby. Lab-created rubies are chemically identical to natural ones, although their appearance may be slightly different upon a very close examination for example, few or unnatural-looking inclusions.

Fake rubies, on the other hand, are typically made from materials such as glass, or from other, cheaper gemstones. We make this recommendation for several reasons:.

In short, everything that works in their favor regarding diamonds is true here as well. As we mentioned earlier, ruby engagement rings are becoming increasingly popular for several reasons:.

In general, buying a ruby engagement ring is a fairly simple process. Rubies can look fantastic in a variety of settings, from white gold and platinum to yellow or rose gold.

Thanks to their lighter color, white gold and platinum have more contrast with the rich red color of a ruby. This makes them both good options if you want the color of the ruby to stand out and attract attention.

These metals both complement fair or rosy skin tones very nicely. White gold and platinum look almost identical to the naked eye, with very little visual difference between the two metals.

Both of these metals complement ruby beautifully, making them good options if you want a ruby engagement ring with more of a warm, vintage feel.

For example, this gorgeous three-stone round cut ruby engagement ring features an 18k yellow gold setting. The elegant, warm color of the setting really complements the rich, dark red of the ruby.

Like other colored gemstones, they also look great in halo settings, which emphasize the rich color of the ruby center stone.

During the late s, a large supply of low-cost materials caused a sudden surge in supply of heat-treated rubies, leading to a downward pressure on ruby prices.

Improvements used include color alteration, improving transparency by dissolving rutile inclusions, healing of fractures cracks or even completely filling them.

The most common treatment is the application of heat. Most rubies at the lower end of the market are heat treated to improve color, remove purple tinge , blue patches, and silk.

The silk is partially broken, and the color is improved. Another treatment, which has become more frequent in recent years, is lead glass filling.

Filling the fractures inside the ruby with lead glass or a similar material dramatically improves the transparency of the stone, making previously unsuitable rubies fit for applications in jewelry.

If a color needs to be added, the glass powder can be "enhanced" with copper or other metal oxides as well as elements such as sodium, calcium, potassium etc.

The second heating process can be repeated three to four times, even applying different mixtures. In , Gaudin made the first synthetic rubies by fusing potash alum at a high temperature with a little chromium as a pigment.

In , Ebelmen made white sapphire by fusing alumina in boric acid. In , Verneuil announced he could produce synthetic rubies on a commercial scale using this flame fusion process, later also known as the Verneuil process.

Other processes in which synthetic rubies can be produced are through Czochralski's pulling process , flux process, and the hydrothermal process.

Most synthetic rubies originate from flame fusion, due to the low costs involved. Synthetic rubies may have no imperfections visible to the naked eye but magnification may reveal curved striae and gas bubbles.

Dopants are added to some manufactured rubies so they can be identified as synthetic, but most need gemological testing to determine their origin.

Synthetic rubies have technological uses as well as gemological ones. Rods of synthetic ruby are used to make ruby lasers and masers.

The first working laser was made by Theodore H. Maiman in Ruby lasers are still in use. Rubies are also used in applications where high hardness is required such as at wear-exposed locations in modern mechanical clockworks, or as scanning probe tips in a coordinate measuring machine.

Imitation rubies are also marketed. A goat herder discovered ruby in the mountains in the s. The clarity of Nepalese ruby is usually low to mid-commercial, although gemmy crystals do exist.

Typically, Nepalese crystals weigh 5 carats or less and have heavy color zoning, from pure red to pinkish-purplish red.
