Ruby, faceted, approx. 5 × 4 mm, from Africa – unique piece
This faceted Ruby from Africa measures approx. 5 × 4 mm and shows an intense red to slightly purplish red color with lively brilliance. The faceted surfaces allow light to reflect across the stone in clear reflections, emphasizing the depth of color and natural transparency. Ruby is one of the classic gemstones and is known for its strong red color, which is caused by trace amounts of chromium within the crystal structure. With its compact shape, this specimen is suitable both for jewelry making and as an attractive collector’s piece.
Geology & origin
Ruby is the red variety of the mineral corundum (aluminum oxide) and is one of the hardest natural gemstones with a Mohs hardness of 9. It forms under high temperature and pressure conditions in metamorphic rocks and is often found in corresponding mineral deposits. Africa is one of the important sources of Ruby and produces material with strong color and natural variation. This specimen shows the typical properties of Ruby in faceted form.
Application note
The stone is suitable, among other things, for jewelry making such as rings, pendants, or earrings, as well as for gemstone collections. Due to its high hardness, Ruby is very durable, but it should still be protected from strong impacts to avoid damage. For cleaning, lukewarm water and a soft cloth are recommended; aggressive cleaning agents are generally not necessary.
