Helenite is a lab-grown crystal using the Silica in the volcanic ash from Mt. Saint Helens in the State of Washington. This is accomplished by fusing the ash at 2700 degrees.  The color is amazingly similar to that of Emeralds and as such, they become a very affordable alternative to that natural gemstone. 
 
Robert has been faceting these crystals over time into various shapes and sizes, including this 15x12mm oval gemstones, weighing approximately 7.5 carats.   He set them in Rhodium-plated Sterling Silver Pendant, along with a 2.5mm faceted White Topaz accent gemstone.
 
We recommend either an 18" or 20" Light Rope Sterling Silver Chain, 1120, for this Pendant.
