The price of a ruby can vary greatly depending on several factors, including the quality of the stone, the size, and the rarity. Generally, the most valuable rubies are those that are a deep red color, without any visible inclusions or blemishes. Larger rubies are also typically more valuable than smaller ones.
The “Four Cs” of ruby pricing are color, clarity, cut and carat weight.
Color: The most desirable color for a ruby stone is a deep, saturated red known as “pigeon’s blood red.” The color should be even throughout the stone and not too dark or too light. Rubies that are too light in color are not as valuable.
Clarity: The best rubies are those that are free of inclusions and blemishes. However, small inclusions are acceptable as long as they do not detract from the overall appearance of the stone.
Cut: The cut of a ruby can greatly affect its value. A well-cut ruby will have a symmetrical shape, good symmetry, and a good balance of color and brightness.
Carat weight: The carat weight of a ruby refers to its size. The larger the ruby, the more valuable it is. However, it is important to note that a larger ruby may not be as valuable as a smaller one if it has poor color or clarity.
In the market, prices of ruby can vary greatly based on the origin of the gemstone. Burmese rubies are considered the most valuable, followed by Thai and Cambodian rubies. Rubies from Africa, such as those found in Tanzania, are also highly valued.
A 1 carat Burmese ruby can cost anywhere from $1,000 to $12,000 per carat, while a 1 carat ruby price from Africa can cost around $300 to $500 per carat.
The price of a ruby can also be affected by its treatment. Rubies are often treated to improve their color or clarity. These treatments can include heating, dying, and glass filling. Rubies that have been treated are generally less valuable than those that are untreated.
When buying a ruby, it is important to be aware of the stone’s origin, treatment, and authenticity. A reputable jeweler should be able to provide certification for the ruby.
In summary, the price of a ruby can vary greatly depending on its quality, size, rarity, origin, and treatment. The most valuable rubies are those that are a deep red color, without any visible inclusions or blemishes, and come from a reputable source. It is important to be aware of these factors when buying a ruby to ensure that you are getting a good value for your money.
