Prehnite gemstones are usually light green in color, with a whitish hue or yellowish tinge. Deep green gemstones are not common. Prehnite gemstones often appear cloudy or velvety, and rarely fully transparent. They may also contain colors zones of lighter and darker green.
The strong citrus tones of this gem type are an unusual quality in the Quartz family. While its sister Citrine enjoys the golden-orange, yellow tones of the sunset, Lemon Quartz has the fresh, vibrant nature of lemon groves in summer. This sensitive tone not only works well in female jewellery but also suits gents cufflinks.
