Details about Heliodor: Value, Cost, and Jewelry Insights
In the realm of precious stones, heliodors hold a special place, known for their captivating yellow hues that range from pale to deep golden orange. This article delves into the fascinating world of heliodors, a type of beryl that has captivated gem enthusiasts for centuries.
Heliodor, meaning "gift from the Sun," can be faceted for jewelry use and is found in various countries such as Brazil, Madagascar, Namibia, Russia, Ukraine, and many others. Notable sources also include Connecticut, Maine, and New Hampshire in the United States, as well as Afghanistan, Cambodia, China, Finland, India, Kenya, Malawi, Mozambique, Myanmar, Nigeria, South Africa, Sri Lanka, Tanzania, Zambia, Zimbabwe, and more [1].
The colour of heliodors varies, encompassing pale yellow, greenish yellow, orange-yellow, and deep golden orange. Some heliodors may even show chatoyancy, a "cat's eye" effect, adding an extra layer of allure to these already striking gems [2].
However, it's essential to note that some pale aquamarines from Vietnam may be treated and sold as natural heliodors. Additionally, treatments such as heating, impregnation, and dyeing are applied to heliodors to enhance their appearance [3].
The term "heliodor" originally referred to golden beryl from Roessing, Namibia, but now encompasses any gem-quality, golden-yellow beryl. Some gemological references distinguish between the terms heliodor and golden beryl, using "heliodor" for beryls with a greenish yellow color and "golden beryl" for beryls with pure yellow to gold color [4].
However, usage varies among gemological sources, with some treating heliodor and golden beryl as the same for yellow-orange to yellow-green beryls [1][3]. The key difference lies mainly in the colour distinction: heliodor = greenish-yellow; golden beryl = pure yellow to gold.
Manufacturers can synthesize heliodors via flux and hydrothermal methods, while natural heliodors can be cleaned using mechanical systems, but a gemologist should examine them first to identify any potential weaknesses [5].
Heliodors make durable jewelry stones, whether faceted or cabbed, and can even occur in sizes large enough for carving. Notable, sizable heliodors can be found in prestigious institutions such as the British Museum (Natural History) in London, England, the Royal Ontario Museum in Toronto, Ontario, Canada, and the Smithsonian Institution in Washington, DC [6].
Ukraine has produced faceted heliodors up to 2,500 carats in weight, showcasing the potential for these golden gems to dazzle even in extraordinary sizes [7]. However, controversy surrounds heliodors from Zelatoya Vada, Tajikistan, as some suspect they may be treated aquamarines and/or colourless beryls [8].
In the world of jewellery, heliodors command top values for gems with high clarity and good color [9]. Whether you're drawn to the subtle greenish tint of heliodor or the pristine yellow of golden beryl, these golden gems are sure to captivate and delight.
