How to determine if a Sapphire is Authentic Sapphire Stone is generally thought to be blue, but it can also be red, yellow, orange, green, or other shades of color. Natural sapphires can be found in soil and water. Synthetic sapphires, on the other hand, are created in the laboratory. To determine the authenticity of a natural sapphire, scan for flaws and intrusions in the stone and perform a breath test. Come across for air bubbles, do a scrape test, and create a light gleam through the gem to discover out if it is a lab made sapphire. Always ask the jewelers for information about the Rubies For Sale they sell to understand what kind of gem it is. Search for the Signs of an Authentic Sapphire 1. Look for flaws and intrusions. Use a jeweler's magnifying glass, at least ten times magnifying, to closely inspect the sapphire. Natural sapphires are formed with tiny pieces of other material, so look for specks and imperfections. These flaws are a good indication that sapphire is real. 2. The synthetic sapphire do not present intrusions of this nature, and some natural sapphires may have no defects, but if you notice imperfections, it is an authentic sapphire. Take the breath test. Take the lab grown sapphire and exhale the air on its surface to mist it. It counts how long the condensation takes before it starts to fade and how long it takes to disappear completely. Natural gemstones should clear in just one or two seconds, while artificial sapphires may take about five. 3. Get certified for your sapphire. Gemologists can examine loose sapphire stones and determine what type of gem it is. They give you their technical report on the sapphire after analyzing it. They can tell you whether it is natural or synthetic, treated or not, as well as many of its other characteristics. Once the gemologists have thoroughly examined synthetic blue sapphire, they will provide you with an official statement. If you have an old family sapphire that you are sure is natural and precious, it is good to have it certified to maximize its value in case you want to sell it. A certified sapphire will be easier to sell at a good price. Find a fake sapphire 1. Check for air bubbles in the gem. The sapphires created in the laboratory are essentially glass, which undergoes a process similar to that which forms Padparadscha Sapphire. Since it is glass, small air bubbles remain inside after their formation. If you see bubbles inside the sapphire, it is a fake stone. Make sure to turn the sapphire and inspect it from every angle. Air bubbles may only be visible from one corner. 2. Run the scratch test. If you have two stones and you identify for sure that one is genuine, use it to rub the second. Gems of equal hardness cannot scratch each other, so if both are real sapphires, then nothing will happen. This test can damage synthetic corundum, so be aware that you can ruin the lower value gem. 3. See how the light reflects off the sapphire. Turn off the lights in a room and aim a flashlight at the sapphire. If the stone is authentic, it will only reflect the light of the same color as the sapphire. If it is false, it means that it is made of glass and will reflect other colors besides that of the gem.
