Opal
Photography by Ken Larsen. Gift of Richard Greenwood, A.F. Greenwood Co., 2005.

The "Hologem" pendant features a round faceted fire opal gem 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.
