Occurrence: In a small number of miarolitic cavities in riebeckite granite in Okanogan County, Washington. This is the only known locality. Crystals up to 35 mm in size have been found, some transparent enough to yield small (less than 2 carats) faceted gems. Typical crystals are 4-15 mm in size, sometimes perched on riebeckite crystals.
Name: After Jack Zektzer of Seattle, Washington, who initiated the investigation of the newly discovered mineral.
