Citrine is one of the least expensive gemstones. Even very big pieces, 50 carats and more, can be easily found on the market. Greenish-yellow and orange stones are more valuable, and heat treatment is often applied to enhance the yellow color., Yellow, brown

Gahnite Vs Citrine Fracture
Fracture is an important parameter when you compare Gahnite and Citrine Physical Properties. It is necessary to understand the significance of these properties, before you compare Gahnite Vs Citrine fracture. Whenever a gemstone chip breaks, it leaves a characteristic line along its breakage. Such lines are known as fracture and are used to identify the gemstones in their initial stages of production when they are in the form of rough minerals. Fracture is usually described with the terms “fibrous” and “splintery” to denote a fracture that usually leaves elongated and sharp edges. Fracture observed in Gahnite is Conchoidal and Uneven. Citrine fracture is ConchoidalMichael OâDonoghue, Gems and Sixth Edition (2006).
Gahnite Vs Citrine Luster
A primary knowledge about Gahnite vs Citrine luster is useful in apparent identifications of these gemstones. Luster is the measure of light that gets reflected when incident on a finished cut gemstone. There are two major types of lusters: Silky and Adamantine. Since luster varies between two crystals of even the same gemstone, luster is limited to basic identification criteria. Gahnite exhibits Vitreous luster. Citrine, on other hand, exhibits Vitreous luster.
