What is meant by a red and blue precious stoneled grow lights
People usually the ruby, blue precious stone said is to indicate generally red, blue of precious stone, actually real ruby(Ruby) and blue precious stone(Sapphire) are to attain precious stone class of just jade(the jade just was a mineral name), the degree of hardness of red and blue precious stone is in the nature in the middle of all minerals only next to diamond, their chemistry composition in order to oxidize aluminum(Al2 O3), pure have no color, implied 0.9%-4% chrome chemical elements assumed red, presented while containing iron and titanium blue;The shape presents three squares crystal fasten, the crystal appearance in the nature is often a pillar-like in shape(the both ends is slightly thin, in the center slightly thick) or plank-like in shape hexagon, external appearance many bucket-like in shape;The color mainly has already had no color, red and blue, the ruby mainly assumes deep purple red or orange red, the blue precious stone mainly presents blue or blue green, the other is green, Huang, powder, brown etc. color;Degree of hardness is 9;Opposite density is 3.99-4.0;Because familiar gather a slice of crystal double, the contact double is crystal, will have a parting;Whole is transparent go to translucent, the sheen presents glass sheen to the second gold just sheen,Pearl Jewelry ruby at purple outside and by lamplight had obvious red fluorescence, blue precious stone the great majority have no fluorescence;The refractive index of usually red and blue precious stone can attain 1.762-1.778, for imply three sets of definite directions to arrange of fiber-like in shape contain the red and blue precious stone of thing, the plain side of the adoption arc-shaped incises, can produce a starlight effect.
The value of the red and blue precious stone measures
The value and its grain size, weight of red and blue precious stone has a close relation, half carat the precious stone as follows is more familiar, cheap;If more than one carat is much expensive, more than 3 carats will be risen with geometric progression.If more than 10 carats, but the quality is again very good, very rare, the value can amount to several USD 1,000,000s.
Generally can is divided into a few following Classes to estimate value:
Less than 0.5 carats, the tiny particle, get very easily and used for cluster to inset very cheap;www.findart.com.cn
0.5-1 carats, the granule, easily get, can use to do small quit noodles, cheapness;
1-2 carats, the medium grain, generally can buy rise, can use to do to quit noodles to hang to fall to;
2-3 carats, bigger grain, are worth of higher, the market demands is big;
3-5 carats, big grain, value Gao, seldom seen;
More than 5 carats, the very big grain, are worth of expensive, very rarely seen.led lighting design
The red and blue precious stone natural article with synthesize the differentiation of article
The red and blue precious stone natural article with synthesize an article in shape is very greatly distinct, first, observe growth line in the precious stone, the method of Yan Rong synthesizes much for the arc-shaped, while what natural crystallize form straightly folds line.Again, inside the observation precious stone of wrap a body, help a Rong the method synthesize to often imply the Rong quality that can not melt in the precious stone a little bit small and to the color Rong remaining of thing, under 2000% magnifiers is”worm-like in shape”;The spirit bubble and small spirit bubbleses with sometimes there is circular, sometimes it is thus clear that the Gan Guo up takes off to drop down of hexagon or the triangle platinum gold slice.The package body in the natural precious stone is mostly some small rutile crystals, or the fingerprint-like in shape spirit liquid wraps a body;Return familiar small crack Xi.The end observes its color and synthesize the color of article too gorgeous, very even, look have a little boring, sting eye, natural article the color and luster then is opposite and soft.
Slice work is also the important factor of influence valuegolden south sea pearl
The red and blue precious stone also pays attention to very much in slicing work and includes to engrave noodles and plain noodles two major type;The shape is oval, the green form, pear form and olives form and mixture form etc. of circular, grandmother.Among them, the hybrid form is most popular, is a wide oval.The evaluation that slices work isn’t as strict as diamond, generally don’t have the very big weight of precious stone value, but if slicing work is very bad and then consumedly influenced its value.
Well slice work to pay attention to 3:00:
1.Slice a work fixed position:Because the red and blue precious stone is each to the opposite sex and have many colors.Should make while incising the pedestal noodles strict perpendicularity is at the major axis direction and avert from much color influence and make the finished product able to see arrive from the pedestal noodles pure and unadulterated most of, saturation of color, this is the correct definite direction.Otherwise cause color iniquity, be subjected to much color influence but take a miscellaneous color.
2.Comparison and symmetry:In spite of precious stone adoption which the kind slice a work type and all want a sign up to standard norm request, and the symmetry is good friends with, don’t can be inclined on one side.Long, the breadth, thick comparison and angle are very important, have to the sign is up to standard, because these are standard according to the total reflection principle of the refractive index and light of precious stone but design, can attain the best effect.If slicing is thin and then will leak light, the color is getting more shallow, the color spreads an effect also bad, say with the professional jargon that then have no “fire head”, call it is “fish eye effect” and seem to be boring and have no brilliance, slicing too thickly will make the color got dark and also influence “fire head”.discount fashion jewellery
3.Throw light degree:Throwing the bare quality will influence the sheen of precious stone.The high quality throws light to make the precious stone presented stronger sheen, flickering become bright.4.Starlight effect:For imply three sets of definite directions to arrange of fiber-like in shape contain the red and blue precious stone of thing, the plain side of the adoption arc-shaped incises to produce a starlight effect.This precious stone slices work to not only want to consider symmetry and comparison, but also the beard choose quasi- direction and position and make the starlight of finished product been located on exact center, if slicing work isn’t good, bias the value then will lower
