Ametrine

Ametrine is especially inexpensive when you consider that it comes from only one mine in the world. Amethyst and citrine colors found in the same crystal of quartz. These bicolor yellow and purple quartz gemstones are called ametrine.

Ametrine is most typically faceted in a rectangular shape with a 50/50 pairing of amethyst and citrine. Sometimes a checkerboard pattern of facets is added to the top to increase light reflection. Ametrine can also be cut to blend the two colors so that the resulting stone is a mix of yellow, purple, and peach tones throughout the stone.

Ametrine is a very durable gemstone suited for a variety of jewelry uses. Most sizes and shapes are available but the color contrast is most pronounced in sizes over seven carats.
