The ruby is different in
jewelry market sales structure and the diamond, it does not have a unified price reference, moreover various countries' ruby entrepreneur also respectively has a set of sales pipeline and the system, says by the entire Earth, the ruby implication mining area is mainly in Asia and Africa, the mining area scale is not big, moreover is independent mining. recent discovery Burmese Ming Su mining area, may say that is in the present world one of biggest mining areas, Ming Su approaches the Thai frontier to flatter fills the gem market, it is estimated that passes through every day flatters to transport to Thailand's ruby, its value possibly reaches as high as over a million dollars, although the Burmese Government has established “the Burmese Gem Auction Company”, sells is from Burma's each kind of gem, but many Burmese rubies, are mostly after smuggle Thailand, sells again to the world. also has discovered for the recent two years in Vietnam the ruby minerals, this production's some ruby color belongs to the red belt purple, including the beautiful pink ruby, this kind of pink ruby when sell, once caused the gem industry stir in the world, many sellers hear a rumor, but to, and seeks to buy massively, but recently this when sells the ruby, is mixed in frequently by the human the man-made synthesis ruby, thus before making many sellers actually step not.
Located at India's south Sri Lanka, also has contained the rich corundum minerals, but this produces the ruby, most is the shallow pink, also has the part to belong to the medium quality flesh color tone ruby. Ruby another habitat, in African Tanzania's Lou river Guido Morocco Lou Yoyo Pakistan canyon, but also has Kenya's Gaga area, produces the ruby in these areas, because the quality not good, the transparency is bad, is only suitable for to cut for the torus day face shape. 1994 year in February spits in the mulberry gem exhibition in the American State of Arizona, presented some to be from India Our Lisa ruby, but south India's other areas, also has discovered some star grain ruby minerals. Moreover, located at Indian north Afghanistan and China's Yunnan area, also has the discovery ruby minerals.
Thailand's Bangkok is the world most important ruby transaction center, the world most little has over 80% ruby through Bangkok, sells in again the international market. Ruby price basis for color, weight, cutting and only, however the decision ruby price's primary factor lies in the color, the quality is best, the price highest ruby, for does not have other any tone purely red, however world each nationality likes to the color slightly having the difference, for example, the European public figures compare on the possibility are partial slightly bring the micro purple ruby, therefore, the international colored gem association regarding the ruby quality, has been unable to schedule an international unification the standardized system, the early gem scientist the pink ruby, schedules for the flesh color corundum name, the time in the ruby first-level, but in 1991 international colored gem The association, induces it into the ruby name, its goal is during the reduction price margin.
Besides the color decision ruby price, the weight is also affects the ruby price the primary factor, the ruby and the diamond equally take the carat as the Unit of measurement, the same quality's ruby pellet is big its price often is by the multiple way valuation. Generally speaking, surpasses 3 carats above rubies, gradually does not have the market standard quotation, but defers to the way which the round turns negotiate a price mutually to trade. If has one to surpass 15 carat high quality rubies, not only may treat as the priceless family heirloom, even treats as the national treasure not. ruby cutting fine or not, presents the color and the radiance influence to this ruby is very big, what a pity common ruby, to preserve its weight, it cuts the proportion to be often unable like the diamond standard. Moreover, an influence ruby's factor, is the ruby interior clean degree, the gem scientist is called only, only the quality will affect the ruby the transparency and the flame, the bad ruby, demonstrated only its in vivo impurity or the crack will be more, this kind of ruby's transparency will be certainly worse, generally speaking, only then the entire transparent ruby, can å¤ cut the facet shape which gorgeous four will shoot, otherwise can only cut the full circle bare day face shape.
Besides the color, the weight, cutting and with to affect the ruby only four big subjective factors, at present affects the ruby price in the market another objective factor is the habitat, however wants
jewelry to decide on the ruby the habitat origin, as if can only the contents which includes by the ruby authenticate, the question is, national boundary delimit is limits depending on political and the military strength, depends on the natural terrain to come the area by no means to separate, therefore, contains in the identical place sierra ruby, has the possibility to deliver extremely in the different country,
jewelry decides in the habitat, also increased many indefinite factors naturally. Also has some influence ruby price external factor, like passes through the ruby which the well-known auction office auctions, its quality had been recognized, the price nature is soaring, perhaps after the important personage, the historical personage has had one's eyes tested and wear glasses the ruby is also creates the high price the foreign factor.
Also some influence ruby value's important human factor, is artificial heating processing. Thailand is the ruby heating processing vital area, the heating processing goal, is in the change or the deepening ruby color, generally the ruby heating treating processes, are put in the ruby in the high temperature boiler crucible to heat up, sometimes heats up the processing personnel will lay aside some glassy materials around the ruby, its goal will be hoped that in boiler's high temperature, will transmit gradually by the material to the ruby, in order to avoid the high temperature suddenly will cause the ruby to rupture, but after heating up, this kind of glass material will adhere to stick cohere in the ruby surface, speaking of inborn the ruby on multi-crackling’s Burmese Ming Su, this vertices, inflow these small cracks gradually, after heating processing finished, kept gem in vivo to be unable mostly to remove, but created packing processing the ruby. According to the world report statistics, the ruby which trades in the
jewelry market, above 90% is at present undergoes this kind of heating the processing method turn color.
The gem scientist believed on the learning that this kind inborn has the beautiful color ruby originally, its price should not with not place on a par after the heating processing natural ruby, but in the market
jewelry entrepreneurs, is actually embracing the different view, they thought that although is undergoes heating processing the ruby, but its color entire life will not change, therefore, should have the good price by rights ought to be only then right. Besides artificial heating processing, the people sometimes in the light red ruby's semblance, spread red pigment, increases the ruby red chromaticity, is only the red raw material which this kind spreads, when mounts the ruby is extremely easy to fall off, therefore not accepts for the entrepreneur and the consumer.
Besides above changes the natural ruby by the artificial method the color, in international ruby trading market, also presents more and more man-made synthesis rubies, is been promiscuous sells in the natural ruby, swindles seeks profit, this kind of man-made synthesis product, is completely is made by the artificial method in the laboratory, the man-made synthesis ruby's low in price,
jewelry to is unable to place on a par with the natural ruby price, is only its beautiful semblance lets the average person be unable to differentiate. Regarding this kind of synthetic gem best resolution method, is differentiates by the ruby content
jewelry decides, at present does the regional legitimate gem institute, how have professor correct to make the discrimination under the microscope, therefore, the purchase ruby's road of best safeguard, is a custom technique, compares goods again, guarantees its quality and the genuine and fake.
