Pigeon Blood Ruby:The brighter the red color of a ruby, the more beautiful and valuable it is. The finest of rubies is known as "pigeon blood red". It is a vivid, intense color that can almost be called crimson and reveals the beauty of the ruby in all its glory. In addition to its purity, saturation and brilliance, its red color gives a strong sense of "burning fire" and "flowing blood".
Pigeon blood ruby Type: corundum Foreign name: pigeon blood ruby.Maximum: 55 carats Feeling: pure, saturated, bright Main sources: Myanmar, Thailand, Sri Lanka.
The ruby with the best color is called "pigeon blood ruby", which is a pure ruby with a hint of blue. Many of the rubies on the market are called Burmese rubies, but not all of them are actually made in Burma, so the jewelry industry refers to the better quality rubies as Burmese rubies.
Rubies are rare and have small grains. The average weight of a single grain is less than one carat, with very few exceeding two carats, and those larger than five carats are very rare. The most valuable is the "pigeon blood" ruby, which is even more valuable than diamond. The world's only very large ruby is found in Burma and weighs 3,450 carats, while the largest pigeon blood ruby weighs only 65 carats.
The most famous pigeon blood red is called Carmen Lucia. "Born in Burma in the 1930s, Carmen Lucia was taken in by the National Museum of Natural History after more than 70 years of wandering, but only the museum knows how much it cost.
In fact, the definition of pigeon blood red is very strict, and there are almost strict rules about color, clarity, hue and color saturation. A few thousand dollars, please think twice before you buy.
Rubies come in a wide range of colors, from red to pink, and are generally of the best quality when they are red, but pigeon blood rubies are the best and most valuable. So, how do you identify a pigeon blood ruby?
The hardness method.
Rubies are the only gemstones with a hardness of 9, as opposed to 8.5 for zirconium oxide, which is often used to imitate other stones.
Therefore, when identifying a ruby, we can use a cubic zirconia to scratch the ruby. If there is no trace, it is genuine; if it is, it is false.
The optical nature of the ruby determines its central ring type and it is the only gemstone with this property, but the test this can only be applied to faceted rubies.
During the test, we place the ruby under a light source and it reflects a beautiful six-star light, also known as six lines. This is due to the ruby's special crystal structure. At this point, we will see an overlap in its double rainbow section, which is a true ruby.
Among the many gemstones, only rubies and red spinels show red to dark red fluorescence under ultraviolet light. Therefore, rubies and red spinels can be singled out by testing whether they are fluorescent.
Whereas rubies are non-homogeneous and red spinels are homogeneous, the difference between the two can be detected with a polarimeter. In this way, the true ruby is picked out.
Some people may wonder about the identification of rubies, as all the previous ones are talking about. It should be remembered that pigeon-blood rubies are also rubies and their nature remains unchanged, and the same identification methods apply.
A natural pigeon's blood ruby is as red as a dove's blood, with a bright, saturated color that gives the impression that blood is flowing through the ruby. This is the main characteristic of pigeon's blood rubies.
Natural rubies are rare and very rare, and naturally, they require a specific environment to breed. The world's most beautiful rubies are found in the Mogok region of Burma, while the rubies of Mozambique in Africa have gradually entered the international arena, attracting the attention of collectors worldwide.
The main sources of rubies are Burma, Thailand, Sri Lanka, Vietnam, Tanzania and China.
(1) Burmese rubies: pure color, vivid and intense saturation. The "pigeon blood red" variety is the most precious ruby in the world and is almost impossible to find on the market. Another type of ruby recently discovered in the Maung Sok mine in Myanmar is dark red or maroon, with opaque milky white or blue tones in the middle, which usually undergoes heat treatment to become more vivid.
(2) Thai rubies: rubies are darker in color, less transparent and have a dark red hue.
(3) Sri Lankan rubies: a large variety of colors, including various series, from light red to red, with high transparency, and famous for its cherry red, which is red with a slight pinkish tint.
(4) Vietnam ruby: purplish red and dark pinkish purple in color, the overall color is between Burmese ruby and Thai ruby, which was discovered in the 1980s. The cleavage is developed.
(5) Tanzanian ruby: reddish to purplish red in color, darker, with yellow tones. Fissure development.
(6) Chinese rubies: The rubies found are, in general, of poor quality, in terms of color, grain size, and transparency. In contrast, Yunnan rubies are of better quality, with purplish-red, rose-red and light red colors, but their cleavage is more developed, thus affecting their transparency.
The ruby collection has several criteria, which are similar to those used to evaluate gemstones in general: color, inclusions, carat and cut. The best color is VIVID RED or RED; the fewer the inclusions, the better, and the better if they are invisible to the naked eye; the cut must be at least 40% fire. In addition, the origin of the ruby is also very important, and an authoritative certificate of authenticity is also needed. If the ruby is heat-treated, it will generally appreciate more quickly if it is over 3 carats, but a non-heat-treated stone of 1 carat or more is a collectible, as non-heat-treated stones of 3 carats or more are too rare. Rubies with a color grade of RED or higher are good.
Generally speaking, "pigeon's blood" describes a ruby's intense and vivid color, as red as a pigeon's blood, and is recognized as the most beautiful color of rubies. Because rubies are usually dichroic, they are usually purplish or pink in color, and it is not easy to achieve pigeon's blood red, which is only found in Burma, where it is rare and extremely low. The best colored ruby color grade internationally is called VIVID RED, and if it is indicated by PIGEON BLOOD, the ruby will be worth even more than a city.
Most rubies on the market are heat-treated, and the industry accepts it. If the consumer is a "no burner" and is looking for a non-heat treated ruby with a high color quality, he or she will have to pay more. Generally speaking, the value of a heat-treated ruby does not drop, but a non-heat-treated stone with excellent color is naturally more valuable.
Certificate of recognition
The most recognized certificate on the international market is the GRS (Gem Research Swiss), founded by Dr. A. Peretti in 1996, which is characterized by its ability to indicate the origin and optimization of rubies, sapphires, emeralds and other stones, with laboratories only in Bangkok, Thailand and Hong Kong. Of course, some dealers also offer certificates issued by the Gemological Institute of America (GIA), but they do not specify the origin of the stones, as rubies are of a single origin, so the GRS certificate is more comprehensive.
First of all, it is important to recognize the bloodline of rubies. Rubies are a type of corundum, and even though some stones such as red tourmaline (tourmaline) are close in color, they are not rubies. Natural rubies are very rare and precious, but they are not too difficult to make, so industrial rubies are artificial. The higher the chromium content, the redder it is, and the reddest is commonly known as "pigeon blood red".
This is due to the special crystal structure of the ruby, which is a unique optical phenomenon. Rubies are transparent, translucent and opaque, and come in shades of aqua, pink, pigeon blood and rose red. Because large stones are very rare, the rubies with larger grains that are normally seen are usually fakes.
There are two types of fake rubies: the first is a low-grade red-colored gemstone masquerading as a ruby, and all fake rubies do not have the characteristic ruby color shape and light. The second type is artificial rubies. Artificial rubies are very similar to natural rubies in terms of specific gravity, hardness and color. Visually, artificial rubies have a uniform texture, are free of natural inclusions, have a uniform and positive color, and are often large in size and lack a natural feel.
Pigeon blood ruby: a ruby as red as pigeon's blood (containing about 20.2% cr), the most precious variety of ruby. The largest known pigeon blood ruby in the world weighs 55 carats. However, most of these stones rarely exceed 2 carats. It comes mainly from the mogok (Burma) and the recently discovered monghsu (Monghsu). Ruby has always been a favorite among collectors because of its hard texture, bright red color and beauty, and "pigeon blood", which is free of inclusions, is a rare find.
