Citrine geodes are rock cavities or vugs with internal crystal formations in colors ranging from pale yellow to deep orange and ranging from transparent to translucent. Citrine geodes can be small nodules cut in half or pieces of larger geodes sold as crystal clusters. Value per carat in citrine, unlike many gems, doesn't rise exponentially with weight as it is readily available in large sizes; but depends almost entirely on color. Named from the French word for lemon,"citron", many citrine gems have a juicy lemon color. Citrine includes yellow to gold to orange-brown shades of transparent quartz. Although the darker, orange colors of citrine, sometimes called Madeira citrine after the color of the wine, has generally been the most valued color, in modern times, many people prefer the bright lemony shades which mix better with pastel colors.
I love GemSelect, personally. I browse their site almost daily to see all the new stones available. Their selection is pretty amazing. The quality isn't always the highest and the cut of the stones isn't always perfect. But for the price, and if you look hard enough, you can find a real gem, so to speak.
