The History Of London Blue Topaz

The most well-known origin story for London blue topaz comes from East Africa, where a deep blue crystal was found by a miner in the 1960s. The miner believed that the crystal was black star sapphire and kept it as his good luck charm. He would show it off to friends and family, who would be amazed at how deep of a blue color it had. Eventually, he took the stone to an expert who revealed that it was not actually black star sapphire but rather a new variety of topaz. The lucky miner then named his find London blue topaz, after its place of discovery and its dark blue color.

Another popular story about the origin of this gemstone is that of Dutch sailor Pieter van Hoorn. In 1616, van Hoorn discovered a strange black crystal while sailing the Indian Ocean with William Pelsaert (who became stranded on nearby Rottnest Island). Van Hoorn concluded that he had found black star sapphire and so nicknamed the stone Pietersite. It wasn’t until 1866 when experts examined his stones that they realized van Hoorn’s black star sapphires were actually just blue crystals of beryl. However, since they couldn’t figure out what to call these stones, they decided to name them after Pieter van Hoorn himself: Pietersite.

Why Is It So Popular?

London blue topaz is one of the most popular gemstones for jewelry. It is often used in rings and bracelets, but also as a center stone or accent gemstone in earrings, necklaces, and pendants. The color is an intense blue that can be lighter or darker depending on the individual gemstone. Black star sapphire is a variety of blue topaz that has black flecks inside it. It’s not uncommon for people to confuse black star sapphire with black opal, which has no color at all. Opals are common in Australia, where black opal is particularly abundant. Opals have a play-of-color effect called schiller. Black star sapphire has no schiller effect because it only contains black spots. The value of black star sapphire depends on its size, quality and clarity; larger stones are worth more than smaller ones.
