About Imperial Topaz - History and Introduction
Imperial topaz is also known as "precious topaz". It is the most sought after natural topaz. Considered to be the color of the setting sun, imperial topaz gets its name from the Russian tsars of the 17th century. This is because the tsars claimed exclusive rights to the pink topaz gemstones that were mined in Russia. Imperial topaz is less common than other types of naturally occurring topaz, which makes it more valuable. Imperial topaz was traditionally considered to be orange with red dichroism, (this means that when tilted in the light, imperial topaz can appear red or orange), but nowadays it is more widely defined as yellow, pink, red, lavender-pink and peach-pink topaz.
Identifying Imperial Topaz Back to Top
Imperial topaz is yellow, pink or pink-orange. The natural pink variety is very rare. Brazilian imperial topaz can range in color from bright yellow to deep golden brown and is sometimes even violet. Imperial topaz can be distinguished from other pink gems such as kunzite, tourmaline, sapphire and ruby by its hardness (8 on the Mohs scale). Ruby and sapphire are harder, at 9, and kunzite and tourmaline are softer. Yellow imperial topaz can also be identified by its hardness; citrine and brazilianite are softer. Apatite, fluorite and zircon are gems that can appear in pink and yellow, but they are softer than topaz. Yellow and pink phenakite can be distinguished from topaz by its trigonal crystal structure. Spinel can be told apart from topaz by its cubic crystal structure. Yellow chrysoberyl is harder than imperial topaz and has a higher refractive index. Precious beryl has indistinct cleavage, thus distinguishing it from imperial topaz, which displays perfect cleavage.

Imperial topaz can be made into an almost limitless variety of jewelry due to its versatility. It is ideal for rings, necklaces, bracelets and pendants because it can be cut into almost any shape. As with diamond, imperial topaz should be protected from hard knocks by protected settings in rings for daily wear. This is because a single blow could cause fracturing due to perfect cleavage. Imperial topaz's hardness (8 on the Mohs scale), gives it durability and resistance to scratches.
Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

Imperial Topaz Gemstone Jewelry Care and Cleaning Back to Top
Like diamond, imperial topaz has perfect cleavage, which means that the force of a single blow could cause it to split. Therefore, protected bezel settings are recommended, rather than pronged settings, for rings that are worn daily. Imperial topaz's hardness (8 on the Mohs scale) makes it durable and means that it doesn't scratch easily. To clean your imperial topaz, simply use soapy water and a soft cloth. Be sure to rinse well to remove soapy residue. As with most gemstones, ultrasonic cleaners and steamers are not recommended. Always remove any jewelry or gemstones before exercising, cleaning or engaging in harsh physical activities such as sports. Store imperial topaz away from other gemstones to avoid scratches. It is best to wrap gemstones in soft cloth or place them inside a fabric-lined jewelry box.
