Much like Kashmir for fine Blue Sapphires, Marambaia Topaz, along with Itinga Topaz, is the quality standard for Blue Topaz. Marambaia Topaz comes in two distinct hues: London Blue and Swiss Blue. London Blue Marambaia Topaz has a beautiful velvety blue that can be mistaken for fine Sapphire, while Swiss Blue Marambaia Topaz displays a vivid blue close to the purest Aquamarine. These colors in combination with an excellent clarity and brilliance create uniquely beautiful gemstones.

Expert cutting is absolutely critical for Topaz and every Marambaia Topaz is carefully faceted by experienced lapidaries. Marambaia Topaz is also finished eye-clean, the highest quality clarity grade for colored gemstones, with a superior polish that results in a beautiful luster.

Traditionally a day stone, Marambaia Topaz also looks great in low-light conditions due to its transparency and high refraction.

One of the birthstones for November, Topaz’s name is either derived from the Sanskrit ‘tapaz’ (fire) or from the Greek ‘topazios’. A gem with an interesting history, if you were an ancient Egyptian you would have called Topaz the ‘gem of the sun’, believing its golden hues were colored by your sun god, Ra. As a Roman, its crystals were a gift from another sun god, Jupiter. In 19th century Russia, pretty Tsarina’s preferred Topaz’s pink and imperial hues, while baby boomers were the first to experience its beautiful blues.


Coming in a diverse array of gorgeous colors, Topaz has a unique crystal structure that makes it a hard and dense gemstone. Topaz’s blues, yellows and browns are the result of color centers, its reds and pinks are caused by chromium and its oranges are the result of chromium and/or color centers. With advances in modern enhancements, today’s gem market has a multitude of color choices for Topaz.

While Topaz is found in Burma, Mexico, Mozambique, Nigeria, Pakistan, Russia, Sri Lanka, USA and the Ukraine, the Brazilian state of Minas Gerais (English: General Mines) remains the premier source.

Marambaia Topaz comes exclusively from the Marambaia Mine located in the Jequitinhonha Valley 83 kilometers north of the gem trading town of Teófilo Otoni. In operation since the early 1900s, Marambaia represents the top two percent of all London and Swiss Blue Topaz, and along with Itinga Topaz, remains the quality benchmark for these gems. The availability of Marambaia Topaz is extremely limited due to low yields and high global demand. Several years of mining is required to accumulate enough Marambaia Topaz for our jewelry collections.
