Deep Dark London Blue Topaz Rough

London Blue Topaz is very popular due to its somewhat unique and unusual color of a deep dark blue hue. The steely dark blue color is a result of the irradiation process and though slightly more expensive than the other, lighter Blue shades of Sky Blue Topaz and Swiss Blue Topaz, it shares the advantages of hardness (8 on the MOHS scale) and availability.

Used in many types of jewelry, Jewelry Designers take advantage of the availability and lower price of London Blue Topaz Rough and cut and polish the material as needed for their designs themselves. Also available in Preform shapes, they save another step in manufacturing the gemstones from the rough. Some use London Blue Topaz Rough in jewelry designs for a different effect that is growing in popularity. The Pleochroic Value of it means London Blue Topaz can show varied color intensity when held in different directions.

Where Is London Blue Topaz Rough Found?

We have ethical mines to source our White Topaz Rough from, and they are located in countries around the world like in Brazil, Orissa India, Mozambique and Nigeria. We either buy the treated London Blue Topaz Rough or send our White Topaz Rough for treatment. The irradiating process of colorless or White Topaz Rough can take years to complete. Irradiation also occurs in the ground to create some naturally colored blue topaz, but not in the quantities and color intensities desired and available to jewelers today.

Most of the natural White Topaz and Light Blue Topaz used for treating comes from Brazil, especially the area around Minas Gerais where the landscape is peppered with thousands of mines, both large and small.  The mines are also known for prolific production of Tourmaline, Aquamarine, Quartz and a variety of other fine gemstones found there.
