Caroline's Jewelry with a Past is offering a 14kt. yellow gold Tie Pin or single Earring mounted with a prong set, cushion cut color change andalusite circa 1970. Color change or pleochroic andalusite is often mistaken for chrysoberyl, although the color change is from green to brown with red flashes. The stone is cushion cut, 8mm. X 8mm. and weighs 1.25 carats (prox). The look of this piece is fabulous and would complement a wide range of colors. It is mounted in a high setting. The piece is in excellent condition.
"Andalusite has a very distinct combination of colors, and a very pronounced level of pleochroism, which results in the exhibition of different colors when viewed from different angles. Andalusite most often occurs translucent to opaque, with transparent gemstone-quality specimens being very rare. For many years, andalusite has primarily been a collector's stone, but it has recently gained a lot of attention from many jewelry designers. It is becoming increasingly popular in jewelry designs. Andalusite possesses a good level of durability and hardness, making it suitable for any type of jewelry application. The attraction of andalusite is greatly owed to its play of color, which can be seen during changes in its viewing angle. Similar effects are also seen when lighting strikes the gem from different directions." Taken from the "GemSelect" website.
The gold has been tested as 14kt. using standard jeweler's testing methods, such as acid testing. The stone was measured using standard jeweler's calipers and tested using a standard jeweler's stone tester. The andalusite was not removed from the piece for weight or size.
