The difference between diamonds and diamonds commonly used in clothing

Nowadays, fashion design is more and more inclined to use materials and design on accessories, and rhinestones are wonderfully applied to clothing. Today, we come to fully understand what is called a diamond.

Diamonds are not diamonds. Diamonds are generic names for imitation diamonds. When buying diamonds, people are afraid to buy a diamond. In fact, the difference between rhinestones and diamonds is great. The value difference is also very large. There are the following types of rhinestones. Xiao Bian reminds everyone here to recognize and purchase.

1. Glass rhinestones: Glass-milled rhinestones are easy to distinguish because of its low refractive index and the lack of true color sparkle of colored diamonds. And this "rhyme" is often used in cheaper jewelry.

2, artificial spinel: it lacks the color of the diamond sparkling light, dip it into diiodomethane, its outline will be blurred. The outline of the real diamond is very clear.

3, artificial sapphire: colorless and transparent artificial sapphire can also be used as a substitute for diamonds after honing. However, it almost disappeared in "diiodomethane", and the edge of the real diamond is dark and very clear.

4. Crystals and Topaz: The transparent crystals of these two natural minerals are similar to diamonds after being ground, but they lack the brilliance of diamonds. And they are all "non-homogeneous bodies", and diamonds are "homogeneous bodies" and are easier to distinguish with polarimeters.

5. Zircon: Zircon is the best substitute for diamonds before the appearance of artificial cubic zirconia. Zircon has a strong birefringence, ie it has two refractive indices, and the difference between the two refractive indices is large. This resulted in a very special optical phenomenon. When observing a polished zircon facet with a magnifying glass, it can be seen from its top surface that there is a clear double image of the bottom face and ridge. Because diamonds are "homogeneous bodies", there is no double shadow phenomenon.

6. Cubic zirconia (“Soviet Union”): This is the ideal diamond substitute or counterfeit product first introduced by the former Soviet Union. It is an artificial compound without natural minerals. Cubic zirconia is very similar to natural diamond in terms of refractive index, dispersion, and the like. However, its relatively low hardness (8.5) is 1.6-1.7 times that of diamonds, reaching 5.6-6, and its thermal conductivity is much lower than that of diamonds, so it can still be accurately distinguished from diamonds by instruments.

Now everyone finally understands the concept of "diamond". Apart from the fact that the glass in the "diamond" is relatively easy to distinguish, the most important thing for other "diamonds" is the gloss. In the natural light, the brilliance of the diamond is always unmatched by the “rhinestone” imitation. It is recommended that you do not buy or purchase under the protection of a certificate issued by a professional and authoritative testing agency if you are in the routine purchase.
