History and General Information of Natural Topaz Gemstone
Natural Pink Topaz GemstoneThe word topaz has been associated with the color yellow and more specifically any gemstone with a yellow or golden hue for centuries. The name topaz is believed to have been derived from the sanskrit word ‘tapas’, meaning fire. It was the mystic fire topaz that was considered to have many healing properties.

However, the modern name of topaz was coined by Henckel, who described the specific mineral deposits in Saxony, Germany with this name.

White Topaz GemstoneTopaz from Ceylon (now Sri Lanka) was used in the 1700s in Egypt and Rome. However, the gemstone gained popularity in Europe only in the 1800th century. Its popularity increased to such an extent in Europe that topaz jewelry became extremely popular and coveted. The gemsotne was also used extensively with the finest diamonds in the jewelry of the Victorian era.

This beautiful gemstone owes its popularity in the middle ages to the myths attached to it. The mystic topaz was believed to strengthen the mind and prevent sudden death of the wearer. Genuine natural topaz was also said to cure weak eyesight. The gemstone had to be soaked in wine for three day and three nights and then placed on the eye for the affect to take place.

Peach TopazThe pink topaz is sometime called the rose topaz. The trace element for the pink, red or purple topaz is mineral chromium. Color center (mean minor atomic substitutions and defects in the crystal structure followed by radiation damage) is the cause of color in yellow, brown and blue topaz. The presence of both chromium and color center results in an orange colored topaz.


Golden Yellow TopazDue to the elongated form of the rough crystals of this gem, usually long faceted oval or pear shape cuts are used to make the most of its color. To retain the color and weight, the topaz gem should be cut in an emerald cut. Due to it weak atomic structure it is very important for the rough topaz to be cut with precision, in a well-planed manner.

However, other than the oval shape or the pear shaped faceted topaz, the gemstone can also be cut into other cuts like the cabochon cut, the square cut, octagon shape or the round cut.

Topaz JewelryTopaz is a transparent and bright gemstone. The most striking inclusions found in a topaz gemstone are drop-shaped cavities containing two or even three immiscible liquids (with a clear dividing line). These topaz teardrop mineral inclusions can be seen on close inspection of the gemstone. However, the presence of even a faint inclusion only reduces the value of the gemstone and good quality, clean gems that do not have any inclusions, especially to the visible eye get higher prices.
