Ametrine Necklaces

Ametrine is a naturally bicolored variety of quartz (SiO2) that combines a violet amethyst zone and a yellow citrine zone in a single crystal – a rare and distinctive property among natural stones. It forms in hydrothermal cavities at around 250 °C, where trace iron is present in different states: color centers related to iron (Fe4+) create the violet amethyst zone, Fe3+ the yellow citrine zone. Its age is estimated at around 100 million years. Its hardness of 7 Mohs is the same as amethyst and citrine.

English names: ametrine, trystine, bolivianite. The esoteric public sometimes calls it "golden amethyst". Chemically, it is the same material as amethyst or citrine – it differs only in the local state of the iron in different sectors of the crystal.

Commercially significant ametrine is mined almost exclusively in one mine in the world – the Anahí Mine in the Santa Cruz department of eastern Bolivia, near the border with Brazil. Bolivia supplies practically all the world's production. The mine was rediscovered in the Bolivian jungle around the 1960s (after centuries of being forgotten), and systematic commercial mining began around the 1980s. Since then, ametrine has become established on the international gem market.

There are rare smaller occurrences in Brazil and India, but they are not commercially significant – their quality and size are much lower. This near-monopoly makes ametrine a valuable collector's stone whose price can rise over time.

The Anahí mine is named after Princess Anahí of the Ayoreo people, who, according to legend, gave her Spanish husband an ametrine crystal as she was dying in the 17th century, as a symbol of faithful but divided love. The princess married the Spanish conquistador Don Felipe de Urriolagoitia, and the mine with the two-colored stones was her dowry. Torn between loyalty to her people and love for her husband (like violet and yellow in one stone), she was killed in tribal fighting. According to the legend, the crystal traveled as a gift to the Spanish queen in the 17th century – and so ametrine came to Europe.

The mine was then forgotten for centuries and rediscovered only around the 1960s. This story makes ametrine a stone with one of the most romantic esoteric stories of all gemstones and a traditional symbol of faithful love and the connection of two worlds.

In esoteric tradition, ametrine is "the stone of duality, harmony and connection" – its power comes from the combination of two stones: the amethyst side brings calm, meditation and spirituality, the citrine side active energy, self-confidence and abundance. The union of both creates balance between the inner and outer worlds, between passive and active energy, the spiritual and the material. It works on the crown chakra (amethyst) and the solar plexus (citrine) at the same time.

It is traditionally credited with harmonizing opposites, supporting decisions between two alternatives, balancing masculine and feminine energy, calm creative work and strengthening relationships as a symbol of two beings united in one. Ametrine is not a medicinal product.

Ametrine is primarily recommended for Libra (23 Sep – 23 Oct) as the perfect symbol of balancing two sides, and for Gemini (22 May – 21 Jun) for harmonizing their naturally dual nature. For Leo (23 Jul – 22 Aug), the citrine side supports self-confidence and the amethyst side tempers the ego. Aquarius (21 Jan – 20 Feb), as an amethyst sign, also gains citrine energy for realizing its ideals. For Pisces (21 Feb – 20 Mar), it helps with the balance between dreaming and reality.

Ametrine is suitable as a birthstone for both February (amethyst) and November (citrine) – an ideal gift for those born in either month. For partnerships, it symbolizes "two souls united in one stone".

Yes – on the market there is natural Bolivian ametrine, heat-treated ametrine (part of the amethyst deliberately turned into citrine), synthetic ametrine (grown hydrothermally, e.g. in Russia) and, rarely, dyed quartz. The most reliable sign of genuine natural ametrine is uneven coloring with natural variation and visible crystal sectors. Natural ametrine shows characteristic crystal sectors when you look at the stone, and natural inclusions typical of natural formation.

Heat-treated ametrine is a legitimate jewelry material, but it is not the result of natural growth. Synthetic ametrine is chemically identical to natural ametrine. To be sure, choose a seller who provides a certificate of authenticity. All the ametrines in our range are natural stones from Bolivia.

In our range you will find four types of necklaces made of genuine Bolivian ametrine – each piece is unique, because no two ametrines in nature are identical. Beaded necklaces are the classic choice, with each bead having its own proportion of violet and yellow. Tumbled chip necklaces offer a bohemian natural look with visible color zoning. S925 silver necklaces with faceted ametrine are the premium choice for special occasions, where the contrast of the two colors stands out best.

Necklaces with an ametrine heart or donut are also available as an ideal gift for a partner. Because of the rarity of the stone (essentially a single commercial source in the world), ametrine is traditionally more expensive than amethyst or citrine alone.

The amethyst side of ametrine fades for the same reason as amethyst itself – its violet color comes from iron-related color centers, which UV light gradually alters, causing the violet component to fade. The yellow citrine side, on the other hand, is more stable. As a result, ametrine exposed to long sunlight may lose the contrast between violet and yellow – its characteristic two-color effect weakens.

Recommendation: do not expose ametrine to direct sunlight, store it in a dark jewelry box and use full-moon light for charging. Do not expose it to high temperatures – the amethyst part could change irreversibly into citrine (at several hundred °C). With proper care, ametrine will keep its two colors for decades.

Yes – ametrine is traditionally considered one of the most romantic esoteric gifts thanks to the symbolism of "two souls united in one stone" and the legend of Princess Anahí as a story of faithful love despite division. The violet amethyst and yellow citrine zones in one crystal perfectly symbolize two different but connected worlds – just like two partners in a couple. The rarity of the stone (essentially one source in the world) further emphasizes the gift.

Ideal occasions are wedding anniversaries, Valentine's Day, engagements and birthdays. Tip: it is ideal to give two ametrine necklaces as a pair – one for each partner, as a symbol of "two in one". Ametrine suits both February and November as a double birthstone.

Ametrine has a hardness of 7 Mohs and is durable enough for everyday wear, but it needs extra care because of the sensitivity of the amethyst part to UV light and heat. Clean it with a soft damp cloth. Polish the silver part with a special cloth. Protect it from direct sunlight – the amethyst part fades. Do not expose it to high temperatures (sauna, fire) – the amethyst could change into citrine.

Take it off before showering, the sauna and sport. Cleanse it energetically by smudging with sage or on a selenite plate. Charge it in full-moon light; charging in the sun is risky because of the amethyst part. Store it in a dark jewelry box to protect its color from UV.
