What are the characteristics of yellow sapphire engagement rings?

According to Do Amore, yellow sapphire engagement rings are known for their hardness and durability. The gems are scratch resistant and less expensive than the more commonly purchased blue sapphires, which can reduce the price of the gemstone by up to 30 percent. Yellow sapphires also come in a large variety of shapes and sizes, allowing for greater personalization of an engagement ring.

Yellow sapphires are rated a nine out of 10 on the Mohs scale of hardness, second only to diamonds. The sapphires vary in color from a green-tinted yellow to an orange-yellow shade. As of 2014, the most popular color of the gem for an engagement ring is a bright canary yellow that falls somewhere in the middle of the range. Prior to being sold as marketable gems, yellow sapphires are often irradiated or heated to increase their color saturation. However, this process can cause the gem to fade in color when exposed to light or heat. The color of the yellow sapphire aids jewelers in examining the gemstones for inclusions. These are a natural result of the formation process and can appear as cavities or liquid-filled spaces within the gem. Most engagement rings use stones with the fewest possible inclusions.
