The cufflinksbecome a prime measure of a man’s taste

Plastic Opal plastic fake, look also change color than the dull. This fake is not difficult to identify because the plastic is very light, the density is only slightly larger than 1 gram per cubic meter. The true the Opal density is 2 grams per cubic meter, double the weight than it. In addition, the plastic is very soft, the nails can scratch it. Opal hardness of the minimum value is 5.5, the nail is absolutely plan does not move. The material of the cufflinks often chooses the precious metals, and some also set with diamonds, germs, etc. At the fire opal posing a fire opal fake, plastic and glass products. The fire opal has not changed color, the color is just beautiful fire-red or orange, if the plastic or glass products made of the same color, you look very some resemblance of the fire opal.
 However, the density of the fire opal is 2 grams per cubic meter of glass than its density is 2.4 grams per cubic meter or higher, while the lighter plastic such as Bakelite was only 1.26 grams per cubic meter, so available is estimated that the density method to distinguish. Not, however, the heavy liquid method to identify how many there are some holes, put the hole in the corrosive and yellow heavy liquid, heavy liquid will be sucked into opal, because Opal, so Opal loses its beautiful appearance of this damage will not be able to eliminate or difficult to eliminate. At the same time, the fire opal is the refractive index is smaller than the plastic and glass. Opal refractive index of about 1.45, while the glass is above 1.5, the plastic is also true. Hence, cufflinks have been put on the aristocratic aura since the birth.
 Therefore, the edge surface stone available light rate meter to measure the refractive index to distinguish them. For the hemispherical prime body stone, used up rate meter to measure the refractive index inconvenience color with dismount: gemstone cufflinks in the refractive index of 1.46 in liquid carbon tetrachloride, fire opal and carbon tetrachloride The refractive index is very similar, that is to use a magnifying glass, will find a real fire opal its shape line in carbon tetrachloride is difficult to see, seems to disappear. As a result, the cufflinksbecome a prime measure of a man’s taste.  Gemstone cufflinks glass or plastic, due to their high refractive index, investment in carbon tetrachloride, the edge and facet clear black border the entire gemstone cufflinks show very clearly in the liquid.
Tourmaline cufflinks characteristics and identification methods; Tourmaline cufflinks, also known as Phi Jesse Pitt wash, is a mineral called tourmaline. Tourmaline cuff is a very beautiful the Intermediate gem cufflinks. The colors green, blue, pink, rose red. The color was pink, green, and its transparency, precious stones cufflinks. Transparent color miscellaneous, used as a valuable jade material. Artist clever use of its natural color, works of art, carved from a variety of scenes such as "green spot" carved leaves, the "pink spot" carved petals, "dark spots" carved insects, composed of depicting realistic natural scene. Selection, collocation and usage of the cufflinks all become a scholarship.
Tourmaline cufflinks divided into the cuff of red tourmaline and green tourmaline cufflinks two categories: pink, red carnation, red roses, red, purplish red color of red, said the red tourmaline cufflinks. Quality by Bach, without any inclusions, flawless, beautiful color, strong flash, look like ruby cufflinks and pomegranate seeds, gemstone cufflinks, only an experienced artist in order according to their flash characteristics, to distinguish between . Light green, green, green, are millet green tourmaline cufflinks. High quality by the color of rain washed plantain leaf is generally green, crystal Bitou, without any inclusions and flaws. To put on cufflinks, you need to roll up the suit sleeve or shirt cuff and then hold the cuffs together. Was found on the cat's eye tourmaline cufflinks, cufflinks of the treasures of tourmaline.
