Inclusions of tiny, slender, parallel Rutile needles in Ruby cause a polished gem to exhibit asterism. A Ruby displaying asterism is known as a " Star Ruby ", and if transparent can be very highly prized.

Star Rubies exists in six ray stars, though twelve ray stars are also known. Rubies must be have good transparency to possess gem value.

Opaque or semi-opaque Rubies have relatively little value, even if they display asterism. The same Rutile inclusions that are responsible for asterism in certain Rubies can also decrease transparency and cause a hazy effect known as silk.

Though Ruby can be one the most expensive gemstones, it also comes in more dull opaque forms that are fairly inexpensive, and are often polished into cabochon s.

A unique gemstone form composed of opaque red Ruby in contrasting green Zoisite is well known from Tanzania, and is used as a minor gemstone and can be carved into ornaments.

Most rubies have a strong red color, although the precise color of rubies can range from blood-red to orangy-red, purple-red, brown-red or even a pink-red tone.

Rubies are made from corundum, a crystalline form of aluminum oxide. When corundum is red, we call it ruby. You can identify a ruby alongside other gemstones thanks to its rich, pink to blood-red coloration.

Men in Black: International. In Pakistani Kashmir there are vast proven reserves of millions of rubies, worth up to half a billion dollars. Rubies, as with other gemstones, are graded using criteria known as the four Cs, namely color, cut, clarity and carat weight.

Rubies are also evaluated on the basis of their geographic origin. Color: In the evaluation of colored gemstones, color is the most important factor.

Color divides into three components: hue , saturation and tone. Hue refers to color as we normally use the term. Transparent gemstones occur in the pure spectral hues of red, orange, yellow, green, blue, violet.

Ruby is defined to be red. All other hues of the gem species corundum are called sapphire. Ruby may exhibit a range of secondary hues, including orange, purple, violet, and pink.

Improving the quality of gemstones by treating them is common practice. Some treatments are used in almost all cases and are therefore considered acceptable.

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.

Flux-grown ruby crystals. Corundum gemstones, both rubies and sapphires, were first synthesized in the late 19th century. In , the French chemist Auguste Verneuil published his work on the flame fusion process, still known today as the Verneuil vair-NAY process.

As a result, the production of synthetic rubies and sapphires skyrocketed. Verneuil synthetic ruby boules largest about 2 inches long.

Many jewelers and gemologists have had the unpleasant task of telling the proud inheritors of treasured heirloom ruby rings or brooches that they contain flame fusion stones with more sentimental than commercial value.
