Black diamonds
are not new. They have been a curiosity for centuries, enjoying
varying degrees of popularity. While some can be quite attractive,
with a very mysterious and alluring character, many people think they
look like the inexpensive stone hematite; some natural black diamonds
have even been misidentified as this much cheaper stone. They are
typically opaque, very heavily included, often with surface reaching
inclusions and fractures that mar desirability. They are also very
difficult to cut, so you often find them with poor makes. Nonetheless,
there have always been collectors of black diamonds and designers who
have enjoyed using them to create unusual pieces. Black diamond
briolettes have also been much sought after for necklaces and
earrings, especially those with an antique look.
