Gift of Richard Greenwood in 2005.This object was designed by Gregory Crawford.

The “Hologem” pendant features a round faceted fire opal mounted in 18k yellow gold and accented with diamonds. The concave high-polish metal captures and reflects the opal’s color giving the appearance of a larger gemstone. The complex optical design gives the pendant a 3-D or holographic appearance, hence the name, “Hologem.” The fire opal, from Mexico, is an intense orange-red color. The pendant was designed by jeweler Gregory Crawford and donated by Richard Greenwood.
