Polki is created from uncut diamonds, whereas Kundan is created from glass stones. As a result, polki shines brighter and costs more. It is created by embedding uncut diamonds in gold jewelry with gold foil and lac. Polski, unlike other diamonds, is not chemically treated... Diamonds are the hardest substance in the world. While trying to improve the look of their jewelry, jewelers have come up with different ways to create products that contain diamonds. One of these products is known as polish. Polish refers to any material that is used to decorate something precious like jewelry or eggs for Easter. The term "polish" also can refer to the process of making objects look shiny. There are two types of polish: natural and man-made. Natural polish includes items such as pearls, coral, and oystershell. These items are all forms of calcium carbonate that has been shaped by nature over time. Man-made polish includes materials like glass and ceramic that have been manufactured into jewelry components. These components are then embedded with diamonds or other gems to produce finished products. Polish prices vary depending on how much diamond is used in the creation of the item. For example, if a jeweler uses a large diamond in his design, it will cost more than one containing less gemstones. Also, quality matters when it comes to polish.
