Heather Dorset's Value, Cost, and Jewelry Details
In the captivating world of gemstones, the term Heliodor often sparks intrigue. While it may be used interchangeably with Golden Beryl, there are subtle distinctions that set them apart.
Heliodor, a variety of beryl, is renowned for its cool, pale yellow colour, occasionally displaying a slight greenish hue. On the other hand, Golden Beryl is characterised by a warmer, richer yellow without green undertones. Some sources maintain a strict distinction, using "Heliodor" for greenish yellow beryls and "Golden Beryl" for those with pure yellow to gold tones. However, other references consider Heliodor as a less vibrant form of Golden Beryl[1][2][3].
The name Heliodor originated as a trade name for golden beryl from Rössing, Namibia. But today, it encompasses a wide range of yellow beryls from significant sources such as Brazil, Madagascar, Namibia, Russia, Ukraine, and the United States (Connecticut). Ukraine, in particular, has produced faceted heliodors up to 2,500 carats in weight[4].
One unique characteristic of Heliodor is the presence of prismatic crystals, which may exhibit naturally etched faces due to changes in the chemical composition of the crystal's growth medium. These crystals can be faceted for jewelry use, and heliodors also occur in sizes large enough for carving[5].
The durability of Heliodor makes it a preferred choice for jewelry. However, it is advisable to consult a gemologist before cleaning to identify any potential weaknesses. Heliodors free of inclusions can be cleaned using mechanical systems[6].
Interestingly, greenish yellow heliodors can be heated and transformed into aquamarines. However, controversies surround heliodors from Zelatoya Vada, Tajikistan, which may be treated aquamarines and/or colourless beryls (goshenite)[7].
Notable, sizable heliodors can be found in museum collections. The British Museum (London, England), Royal Ontario Museum (Toronto, Ontario, Canada), and Smithsonian Institution (Washington, DC) are among those that house impressive heliodor specimens. The Smithsonian Institution, for instance, has a 2,054 carat rectangular step cut yellow heliodor from Brazil in its collection[8].
Manufacturers can synthesize heliodors via flux and hydrothermal methods. Despite this, the natural beauty and allure of genuine heliodors continue to captivate gem enthusiasts worldwide[9].
