Citrine

Because citrine occurs in large crystals and much of the supply is produced by heating amethyst, stones of significant size are common. Carat weight affects value mainly for particularly fine color stones or unusual cuts above about 10–15 carats; smaller sizes are priced primarily on color, clarity and cut quality.

Color is the key value factor: intense, pure golden yellow to rich medium orange hues with good saturation are most prized, especially when not overly dark or brownish. Very dark, brownish stones or very pale, washed-out yellows are less desirable and command lower prices.

High-quality citrine is typically eye-clean; visible inclusions are not well tolerated in faceted stones intended for fine jewelry. Stones with internal feathers, clouds or color zoning that disrupt face-up appearance trade at a discount.

Citrine is most often cut in standard brilliant, mixed and fancy shapes. Good cutting that maintains consistent color across the face, avoids windowing and provides lively brilliance is important; novelty fantasy cuts and designer shapes can command premiums when executed well.

Most commercial citrine is either natural or produced by heating amethyst and smoky quartz, primarily from Brazil, with additional supply from Africa and other quartz-rich regions. Overall supply of gem-quality material is very large, with no significant geological scarcity at current demand levels.

Demand is broad and steady, driven by citrine's affordability, warm color and status as a November birthstone. It is used in both mass-market and high-fashion jewelry, and in metaphysical markets it is often associated with prosperity and confidence.

Demand for citrine has remained stable, with slight increases in interest for high-quality designer cuts and for citrine paired with amethyst in ‘Ametrine'-style pieces. Prices for commercial material remain modest due to abundant supply.
