While not as popular or valuable as its blue counterpart, yellow sapphire is a stunning precious rock. The stone is also significant in Hindu or Vedic astrology. Regardless of why you choose a original yellow sapphire, learning how to verify the stone to ensure that it is genuine, natural, and generally flawless is a crucial step to take before making a purchase.
#Test 1: Glass vs Yellow Sapphire
Consider the original yellow sapphire in comparison to a piece of yellow glass. While yellow glass may appear similar to original yellow sapphire at first glance, the two are vastly different. The majority of imitation sapphires are constructed of glass. Yellow glass, in general, is too huge and too colourful to be authentic.
#Test 2: Check for bubbles
Look for tiny bubbles. Sapphires can have numerous inner inclusions; however, high-quality genuine yellow sapphire will not have apparent inclusions. False sapphires, on the other hand, frequently contain small bubbles inside.
#Test 3: Do scratch test
Examine the surface for scratches. Any colour of sapphire is exceedingly hard. The hardest gemstone is diamond, which ranks a 10 on Moh's scale of mineral hardness, while original yellow sapphire ranks a 9.0 on the same scale. As a result, only a few materials can scratch sapphire. On the other hand, glass has a hardness rating of 5.5 to 6.0 and is much more easily irritated. Surface scratches are every day in glass imitations of yellow sapphire, although the original yellow sapphire has very few if any.
#Test 4: Check for inclusions
Take note of the facets. Because glass is not as hard as sapphire, it is considerably easier to cut. Yellow glass stones are usually cut simple and have smooth, rounded edges. Original yellow sapphire, on the other hand, have more complicated cuts that are sharp and crisp.
#Test 5: Observe the cut
Take note of the cut. Original yellow sapphire can be cut into practically any style on a modest scale. However, as stones exceed one carat in weight, many jewellers cut sapphires into oval or cushion mixed cuts. However, because of more popular round and emerald cuts, jewellers frequently cut synthetic stones into the round and emerald forms. Natural sapphires can theoretically be cut into the same shapes, although this is far less common. Visit Gem Selections for more information.
