There are not many yellow gemstones in the world of jewels. A diamond or a sapphire may be yellow – but it will be expensive – or sometimes a tourmaline or chrysoberyl, though they tend towards green. However, citrine fulfils everyone's colour wishes, from lemon-yellow to reddish-brown.
The supply in Europe of sufficient raw material came at just the right moment for the nascent upheaval in social conditions. As the bourgeoisie grew in strength, the demand for jewellery across a broader spectrum of social strata also grew, and citrine found a permanent niche for itself. Since it was really only topaz that until then was known and used as a gold-coloured gemstone, the yellow and brown crystal quartzes quickly became very popular with ladies.
