There are gemstones that are extremely similar in colour, yet their characteristics are vastly different. People get confused by similar colours, and dealers take advantage of this uncertainty by scamming them. Yellow sapphire, citrine, and yellow topaz are examples of this. Since these three diamonds are yellow, they have created difficulty in choosing the gemstone.  Due to the obvious similar hues, people may mistakenly purchase citrine rather than yellow sapphire or yellow topaz instead of Pukhraj while shopping for a rich yellow coloured gemstone. That is why it is essential to consider their variations.  Let's look at the characteristics that distinguish these three gemstones.

Hardness of Yellow Sapphire

On the Moh's scale, Pukhraj is a 9 on the hardness scale. The hardness of yellow topaz is 8, whereas the hardness of citrine is 7. The difference in hardness between these three gemstones reveals how tough is Yellow Sapphire. Pukhraj is an excellent choice for anyone seeking a long-lasting yellow gemstone.

Minerals 

Gemstones' appearance is heavily influenced by the mineral family to which they belong. The yellow sapphire belongs to the Corundum family of gemstones. The quartz family includes citrine, while the topaz family includes yellow topaz.

Optic Properties

A gemstone's optical characteristics define whether it is singly refractive (SR), doubly refractive (DR), or mixed. A gadget known as a polariscope is used to identify the gem's optical nature. DR uniaxial, DR biaxial, and DR uniaxial are the optical properties of citrine, yellow topaz, and yellow sapphire, respectively.

Refractive Index

The Refractive index is a measurement of how much light is bent or delayed as it travels through a substance. Citrine, Yellow Topaz, and Yellow Sapphire, respectively, have refractive indexes of 1.544-1.553, 1.610-1.620, and 1.760-1.770.

Specific Gravity

The specific gravity of a gemstone is calculated by dividing the density of the gemstone by the density of water. Citrine has a specific gravity of 2.65, yellow topaz has a specific gravity of 3.52, and yellow sapphire has a specific gravity of 4.00.

Precious and semi-precious 

The majority of people wish to buy expensive jewels, but the identical colours make it tricky to differentiate. Always keep in mind that yellow sapphire is a valuable gemstone. Citrine and Yellow topaz, on the other hand, are semi-precious stones. One must keep these characteristics in mind while shopping for Pukhraj, and be safe from dealers who try to trick anytime.
