Style and the productive technology of cufflinks always reflect the characteristics of that era

How to identify the gemstone cufflinks and glass products? Nature as the raw materials of mineral crystals of gem cufflinks are very rare, so their prices are quite expensive at the same time, the output is difficult to meet consumers' growing demand. In this way, people took advantage of modern technology, to create a gemstone cufflinks substitutes - glass. Glass is the first gem cufflinks substitutes and bogus products. Due to the rarity of this material, the cufflinks made from black glass become a popular alternative for the funeral.  The glass can have any color, very close to nature with a variety of gemstone cufflinks. In order to distinguish between the gemstone cufflinks and glass, the following simple and non-destructive methods can be used:
The tongue lick law gemstone cufflinks are crystal, heat transfer is relatively fast, the glass is amorphous, heat transfer is slow. Therefore, when the tongue lick samples, gemstone cufflinks have a cool sense of the glass temperature sense. A magnifying glass with a magnifying glass to carefully observe the samples can be found, the glass surface and inside often curved or swirling thin lines, often small or large bubbles, where to see samples of these phenomena, can be concluded that It is glass rather than a gemstone cufflinks. Style and the productive technology of cufflinks always reflect the characteristics of that era. Refined quality can be found with a magnifying glass observation sample, glass polished quality is very rough. Some casting, therefore, some of its plane is often not enough flat, often raised or pits, some cross-edge is not straight, and natural gemstone cufflinks pondering the quality is generally very fine.
Parting, no step-like structure, with conchoidal fracture, and its black outer adherends is too soft, and hard shiny fusion crust entirely different. color compared with the natural ruby cufflinks, trace element species in the flame fusion synthetic ruby cufflinks single artificially added to the content of Cr2O3, so its color is too pure, bright, gives not realistic. Almost everything will appear on the cufflinks, including the flora and fauna, architecture, and famous people of all times and events. China's market, the early circulation of the flame fusion synthetic ruby with bright red, pink and two varieties, pink varieties as a blue tint of pink. Pink sample rotation there is a clear blue flash, natural ruby cufflinks rarely have this phenomenon. However, with the production process of continuous improvement, more and more the color of the flame fusion ruby cufflinks, dark red, orange-red, purple and other colors, color perception can only put forward some kind of "warning" does not do the only basis for identification.
The pleochroism natural ruby cufflinks, especially large particles of natural ruby cufflinks, table orientation generally vertical z-axis. When observed from the table the natural ruby cufflinks with dichroic mirror, you can not see the two-color or two colors is not obvious. Flame fusion synthetic ruby cufflinks, boules, due to stress, often from the middle or nearly parallel to the z-axis direction, split, in order to make full use of raw materials, flame fusion synthetic ruby cufflinks table is parallel or nearly parallel to the Z-axis orientation , the color of the table tend to be orange-red, not very satisfactory, from the countertops observation can be seen more pronounced dichroism. Dichroism in this observation can not be used as a decisive basis for identification, however, when the dichroism observed abnormal enough to raise the alarm (see Figure 3-1-171). Political campaign, opera star, myths and legends cufflinks are all very typical, and always the favorite of collectors.
