Ametrine Buying Guide for Jewelry
Ametrine is one of the world's most unusual gemstones considering that it is actually two stones in one. Two colored ametrine mixes the golden sun yellow of citrine with violet amethyst. To be classified as an ametrine, the gemstone must display both purple and yellow hues. Only a very small percentage of the rough contains both colors and is considered ametrine

The color split is usually highlighted by cutting the stone into long shapes perfect for rings, earrings and necklaces. Larger ametrine gemstones make especially enchanting pendants and cocktail rings, perfect for party wear.
Ametrine Color:
Ametrine is all about the color and sets it apart from other varieties of quartz. Ametrine gems can vary in both color split and color intensity, but the most sought after stones exhibits a 50-50 split or intense purple to deep yellow.
Ametrine Clarity:
Ametrine stones, like most other clear quartz varieties, are typically free from visible inclusions and transparent.
Ametrine Cut/Shapes:
Ametrine is typically cut into octagon and Asscher cut as these are ideal for showing off the bicolor appearance. Lately Ametrine has also been cut into fantasy shapes.
Ametrine Weight:
Ametrine is often found in large, clear crystals so it is fairly common to find larger carat weight gems at reasonable prices.
Ametrine Treatment:
Ametrine is not typically treated or enhanced. Ametrine is sometimes lightly heated or irradiated, but these enhancement treatments are not routine.
Please Note: There are synthetic variants of ametrine. If you are unsure, you should always ask the seller to certify the stone, but a warning signal is always if you see very large stones (20 carat +) being sold at very low prices. Another warning signal is if you see stones that have, for example, a blue/yellow or blue/green color, these colors do not exist naturally in ametrines, so these stones are always 100% synthetic!
Ametrine Price:
Ametrine is a very rare gemstone but is still quite affordable, especially compared to other bicolored stones like alexandrite or watermelon tourmaline. A good quality ametrine should range in price from $10-$50/ct.
Ametrine Hardness:
Ametrine has a hardness of 7 on Mohs hardness scale which makes it strong enough to be used in all type of jewelry such as rings, earrings, pendants, bracelets and more.
Ametrine Birthstone:
Ametrine is in itself not a birthstone. However, since ametrine is the bicolor union of both amethyst and citrine, ametrine combines the powers of both. Therefore, ametrine can be the birthstone for those born in February and November.
Ametrine Zodiac Stone:
Traditionally, the zodiac signs of ametrine are Pisces (Pisces, February 19 – March 20) and Sagittarius (November 22 – December 21).
Ametrine Anniversary Stone:
Amethyst is the 6th wedding anniversary gemstone, and citrine is the 13th wedding anniversary gemstone so Ametine can be used for both these anniversary dates.

Caring for your Ametrine Jewelry:
