Many women like to mention diamonds. Because it represents not only romance, value, but also represents the mind. If women can receive a diamond ring that they are satisfied with when they get married, it must be a plus. However, there are many kinds of diamonds. How can we identify whether it is a high-quality diamond? Below, the relevant experts will give you a simpler and quicker way of identifying and facilitating your purchase.
According to relevant sources, diamonds are the hardest substances in natural materials. Diamonds can be used to characterize any other gemstone, but any other gemstone is characterized by immovable diamonds. Can also be used "standard hardness tester" characterization, where the hardness is less than 9 degrees, are fake diamonds. Diamonds also have lipophilicity. For example, if a pen draws a line on the surface of a diamond, it becomes a continuous line, while other gems show intermittent lines. The above method has certain reference value in identifying diamonds. It can also be observed through a 10x magnifier. Under a 10x magnifier, most diamonds can be seen as halos, and there are triangular growth patterns. The surface of the diamond has "red, orange, blue" and other "fire" light. shining. The most accurate and reliable method is to use "thermal conductivity meter" to measure the thermal conductivity data to distinguish between true and false diamonds, but the "thermal conductivity meter" is more expensive. As diamonds are noble and luxurious jewellery items, it is not uncommon for cheap gems, synthetic gems and even glass to replace or claim diamonds on the market. Commonly all kinds of fake diamonds come in the following categories:
1 Zircon: Very similar to diamonds, it is the best substitute for diamonds. The identification method is that zircon has a polarization and a large birefringence. When observing a zircon facet after processing with a 10x magnifier, looking from the top to the bottom, it can be seen that the ridges at the bottom have obvious double lines. Shadow, and diamonds have no double shadow phenomenon.
2Glass: The refractive index of glass is very low, there is no flashing colored light of diamonds; especially when sinking into water, the glass products have no glory and they immediately show their feet.
3 Soviet drilling: Cubic zirconia, first developed by the Soviet Union, was named. Soviet drills are man-made compounds, but they are close to natural diamonds in terms of dispersion, refractive index, etc. They also have the attractive appearance of “fireâ€. But its lower hardness (8.5) can be distinguished from diamonds. And the thermal conductivity is much lower than that of diamonds, which can be identified by the “thermal conductivity meter†and accurately separated.
4 Crystal: Although crystal is a natural mineral transparent crystal, it looks like a diamond after processing, but it lacks the colored light of the diamond.

LED street light has revolutionized outdoor lighting, offering numerous advantages over traditional lighting technologies. With their energy efficiency, long lifespan, and superior performance, LED street lights have become the preferred choice for illuminating roads, pathways, and public spaces. However, not all Outdoor Adjustable Street Light Fixture is created equal. There are various classifications and types of LED street lights available in the market, each designed to meet specific requirements and deliver optimal lighting solutions.One of the primary classifications of Outdoor LED Street Lights is based on their wattage or power consumption. LED street lights are available in a range of wattages, typically ranging from 20 watts to 400 watts or more. The wattage determines the brightness or lumen output of the Outdoor LED Street Light, and different wattages are suitable for different applications. Lower wattage LED street lights are often used for residential areas, pedestrian pathways, or small parking lots, while higher wattage lights are more suitable for major roads, highways, and large parking areas.
Another important classification of LED street lights is based on their optical design and light distribution patterns. LED street lights are available in various beam angles, including wide, medium, and narrow beams. The beam angle determines the spread and concentration of light, allowing lighting designers to choose the most appropriate option for specific applications. For example, a wider beam angle may be preferred for illuminating large open spaces, while a narrower beam angle may be more suitable for focusing light on specific areas or reducing light pollution.
