How to judge the quality of rhinestones? 5 tips for wholesale high quality rhinestones

How to judge the quality of rhinestones? 5 tips for wholesale high quality rhinestones

2020-06-23

There are so many rhinestones on the market that we often hear about Swarovski rhinestones, Austrian diamonds, resin diamonds, and acrylic diamonds. There is also a diamond word, which looks similar from a distance, but the price varies greatly. What is the difference? How to choose the right rhinestone? How to judge their quality?


This article introduces five methods for judging the quality of rhinestones from the perspective of materials and production methods. Knowing these tips can help you find the most suitable product when purchasing or wholesale rhinestones.

Rhinestones are diamond simulants made of crystal. After the 19th century, crystal glass or acrylic materials were extended.


These commonly-used terms such as Swarovski rhinestones, Austrian diamonds, and acrylic diamonds are different artificial diamonds. In order to decorate all kinds of clothing, jewelry, accessories, etc., people make artificial diamonds to give accessories a shiny, high-quality texture.


Therefore, we can also say that these rhinestones are all diamond substitutes, and the difference lies in the degree to which they replace diamonds. Some have 80% diamond characteristics (including hardness, cutting, and shimmering texture), while others only have similar appearance and texture.


How to judge the quality of rhinestones?

First, first determine the material of the rhinestone. Different materials have their own characteristics, and differences between materials are unavoidable. For example, glass has a high melting point and heat resistance (about 1000 degrees) and a high density and hardness. In contrast, a rhinestone made of acrylic material has a low melting point (about 130–140 °C) and is not heat resistant, and the density is lower than glass, so it is softer. .


The rhinestones of various materials on the market are roughly divided into Swarovski crystals, Oscars (Australian diamonds), glass diamonds and plastic diamonds. Judging by the price, you can know the quality of these rhinestones. As the saying goes, for every penny you get, the most expensive Swarovski rhinestones are the best quality rhinestones. Swarovski has a long history and is a leading brand of crystal diamonds. It is well-known internationally and has a unique cutting process to manufacture well-known crystal gems in the industry.


Therefore, in terms of materials, Swarovski rhinestones have the best quality, followed by Treasure Osa rhinestones, followed by plastic diamonds, including acrylic and resin diamonds.


The same material, but also different qualities

If you have the experience of purchasing rhinestones, you may have encountered this situation: rhinestones of the same material, obviously the same size and color, but why the price is so different? How to judge their quality?


"The devil hides in the details." If you can understand the method of judging the quality of rhinestones, you can understand the difference between price and quality, and select the most suitable rhinestone!


Of course, the judgment methods of rhinestones of different materials are different. Next, we will explain how to judge the quality of acrylic rhinestones for acrylic drills.


Five methods to judge the quality of  wholesale rhinestones

1. Brightness of rhinestones: related to raw materials, molds and injection technology

The reason why rhinestones will shine and shine is because of the high light transmittance of rhinestone materials. In addition, the light enters the bottom of the product and is formed by the light refracted through different cutting surfaces.


When we use rhinestones, we use the glittering characteristics of diamonds to decorate clothing or accessories to make accessories shine. Therefore, the shining degree of rhinestones is what we can observe. The rhinestones with better quality usually have higher flashing and translucent degree.


What does the transparency of the rhinestones have to do with it? The following are three aspects of raw materials, molds and injection technology.


1. Raw materials

If better rhinestone materials are used, the transparency of rhinestones is usually higher. This concept is like the importance of ingredients in cooking. If you use high-quality ingredients, the dishes you cook are usually very top-notch.


2. Mould

The rhinestone is injection molded through the mold, so the quality of the mold will also affect the quality of the rhinestone. A pair of high-quality molds can produce acrylic diamonds with smooth and smooth surface and high-brightness rhinestones.


What about good molds? It can be known from the manufacturing process and method of the mold. Usually a high-quality mold, the cost is very high.


3. Injection technology

In addition to the mold, injection technology is also a factor. The quality of plastic injection products depends on many factors, such as temperature and time. An experienced master can judge the most appropriate production factor and produce high-quality products.


2. Whether the cutting/cutting surface of the rhinestone is smooth

If there is no opportunity to directly contact the original manufacturer, you can observe from the appearance of the rhinestone.


Because the flickering of rhinestones is caused by the refraction of light, if the surface is flat, the light refracted is more medium and shiny. So, you can take a closer look to see if the cutting surface of the rhinestone is sharp? Is the surface smooth?


3. Is the water injection port (injection port) smooth?

The interface at the edge of the rhinestone is the injection water outlet that will inevitably occur during the injection molding process. If the injection nozzle is not properly treated, there will be burrs, which can easily puncture and scratch the skin. Therefore, you can touch the edge of the rhinestone to determine whether the nozzle is smooth and flat. If the nozzle is smooth and flat, the quality of the rhinestone is better.


4. Whether the silver bottom is easy to peel off

The injection-molded rhinestones are completely transparent and cannot show a shimmering luster. Therefore, the semi-finished product after injection will be electroplated again, and a silver layer will be plated on the bottom of the product to make the rhinestones shine.


5. the color is the primary color shot? Or dye?

The colorful rhinestones are suitable for different design styles. The rhinestone color is formed in different ways, some are formed by post-processing dyeing; some are shot out of the original color (that is, the color is produced)


If it is through dyeing, the color is unstable and easily fades, and the color of each batch is difficult to control accurately. But the advantage is that almost all colors can be achieved by dyeing, and the price is lower. If the primary color is emitted, the color is more consistent and stable, and it is not easy to fade.
