While not as costly as its counterpart, yellow sapphire is still a beautiful gemstone that embellishes any type of jewelry and makes it look all the more gorgeous and appealing. The stone is also known for its vast range of astrological benefits and much more. Irrespective of why you choose a yellow sapphire, you should however ensure its authenticity before purchasing, as there are also a plethora of imitations available. In this how to guide you will read about various characteristics involved in buying a genuine yellow sapphire.
Distinguishing between Real and Fake Sapphires
Compare the original yellow sapphire with yellow glass. Mostly the imitations are made from yellow glass. Although they may look similar to original sapphire at first glance but when compared you will find a discrete difference between the two.
Look for bubbles. Sapphire can have several interior inclusions, but the bubbles in genuine ones can’t be seen from naked eyes. However, fake sapphire have tiny bubble entrapped inside that can be seen with naked eyes.
Check for scratches. Ranking at 9th position as per Moh’s scale (a scale used to measure relative hardness of a mineral by its resistance to scratching), yellow sapphire is just one level lower than diamond that is placed at 10th position. Therefore, sapphire of any color is extremely hard, which means it’s relatively harder to cause scratches on sapphire. On the contrary, an imitation often has lots of scratches on their surface; this is another reason to differentiate between an original sapphire and a fake.
Consider the facets. Since a glass is not as harder as original sapphire, hence the former one can be easily molded into various shapes and usually have smooth and rounded edges. However, original sapphires have more complex cuts that have sharp and crisp edges.
Take note of the cut. Below one carat an original yellow sapphire can be cut into almost any shape, but beyond one carat jewelers prefer to cut it into either oval or cushion mixed cut. On the other hand jewelers often cut synthetic stone into oval and emerald shape.
Avoid ‘x’ cuts. Fortunately, manufacturers of synthetic stone usually place an X cut, also called a scissors cut, on the facets of a stone.
Check the stone under a magnifying glass. A synthetic stone, no matter how original it may look, will definitely possess some flaws which can be easily identified under 10x to 30x magnification. A magnifying glass will help you identify the curved and groove banding found in synthetic sapphires, especially when you place a translucent glass in between the stone and the light.
Be cautious of filling. Some sapphires often contain some space inside them, which on slicing may showcase imperfection. Although some jewelers leave the space as it is, but some fraudulent ones fill the gap with borax paste or dust of glass to add on to the weight of the stone. Patches of unevenness is considered as a good indication of this swindling practice.
Say no to foil backed stones. Foil backing adds on to the deep colorization and luster that makes the stone look brighter than ever. The backing could be really hard to notice any difference from naked eyes, but by examining the base of the stone with a magnifying glass can often reveal a foil backing. This type of practice is more common in antique type of jewelry, hence observe them carefully.
Look for a genuine provider. Always purchase a gemstone from a provider who is certified to sell gemstones. However, the certification may not give you the surety of genuineness like physical checking of the stone might, but it does provide you the satisfaction that the gem is approved of the officials of a trusted organization.
