From the ground, diamonds appear as sparkling, clear gemstones, reflecting light in a dazzling array of colors. Their brilliance is enhanced by their faceted surfaces, which create a spectrum of light reflections. However, without magnification, they can often look like small, shiny stones rather than the iconic gems they are known to be. The allure of diamonds lies not only in their appearance but also in their rarity and the emotions they evoke.
That depends, some gems are being made now to look almost completely like the real thing. However these are marked specifically because they are so hard to tell from natural diamonds. However, cheap diamonds that are crystal or glass will be obvious form the naked eye due to the clarity, and color.
One way to spot a fake diamond is to check the diamond's clarity and color - fake diamonds often have imperfections and lack the sparkle of real diamonds. You can also use a loupe to look for any imperfections that are typical of lab-created or synthetic diamonds. Finally, taking the diamond to a professional appraiser or jeweler for testing can confirm its authenticity.
In the field, any clear or translucent stone may be mistaken for a gem-quality diamond. The field test for diamond is 'extreme hardness'. In the jewelery store, many natural gems can appear diamond-like, given the top look of a diamond. Look-alikes can include Moissanite, sapphire, quartz, topaz and so forth. There are also manufactured gemstone look-alikes, generally called CZs.
