Maxixe Beryl

Beryl · Be₃Al₂Si₆O₁₈ · Mohs 7.5–8

In short

Maxixe Beryl is a beryl, Be₃Al₂Si₆O₁₈, and sits at 7.5–8 on the Mohs scale. NO₃⁻ or CO₃⁻ radiation-induced colour centre — not iron gives it its colour. Most of what is traded comes out of Maxixe Mine, Minas Gerais, Brazil. Irradiated beryl whose deep blue fades, sometimes within weeks, under light or mild heat.

Treatment
Irradiated beryl whose deep blue fades, sometimes within weeks, under light or mild heat. Distinguished from true aquamarine by reversed pleochroism (deep blue down the c-axis) and an unusual absorption spectrum. Selling it as aquamarine is a persistent fraud; the colour instability is inherent and not correctable.

What maxixe Beryl actually is

Maxixe Beryl is classified as beryl, with the composition Be₃Al₂Si₆O₁₈. It crystallises in the hexagonal system.

Colour comes from nO₃⁻ or CO₃⁻ radiation-induced colour centre — not iron, which is also what a laboratory looks at when it is asked whether a colour is natural.

Refractive index 1.578–1.584. Specific gravity around 2.68–2.80. Cleavage: imperfect basal. Those three numbers separate it from most of what imitates it.

Where maxixe Beryl comes from

Maxixe Beryl is produced at Maxixe Mine, Minas Gerais, Brazil and Madagascar.

The locality is part of the description, not a footnote — two stones of the same weight from two of these places are not the same stone.

How maxixe Beryl is treated

Irradiated beryl whose deep blue fades, sometimes within weeks, under light or mild heat. Distinguished from true aquamarine by reversed pleochroism (deep blue down the c-axis) and an unusual absorption spectrum. Selling it as aquamarine is a persistent fraud; the colour instability is inherent and not correctable.

Treatment changes value, sometimes by a multiple, so it belongs in the description before the price and not after the sale.

What maxixe Beryl is confused with

In the trade maxixe Beryl is most often mistaken for, or substituted by, Aquamarine, Blue topaz, Blue zircon or Irradiated blue beryl.

The separation is rarely a matter of opinion: refractive index 1.578–1.584 and specific gravity 2.68–2.80 settle most of it in a minute, and magnification settles the rest.

What maxixe Beryl is used for

Demand for maxixe Beryl comes from mineral collecting, which is why one price per carat never covers it.

We quote each application in the unit that trade actually buys in, by the specimen.

Durability and care

Hardness 7.5–8; cleavage imperfect basal. That combination decides what it can safely be set into.

Hardness is not the whole story. Perfect cleavage means the stone can split cleanly if struck along the wrong plane, whatever its Mohs number, so a protective setting matters more here than the hardness suggests.

Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.

What maxixe Beryl costs

As a guide, maxixe Beryl trades around Low and unstable — fades; not a commercial gem.

That is a range, not a quote. Colour, size, clarity, cut and origin move the figure a long way inside it, and the only honest price is one given against a specific stone. Send us what you need and we will price it.

Questions

Is maxixe Beryl treated, and how?

Irradiated beryl whose deep blue fades, sometimes within weeks, under light or mild heat. Distinguished from true aquamarine by reversed pleochroism (deep blue down the c-axis) and an unusual absorption spectrum. Selling it as aquamarine is a persistent fraud; the colour instability is inherent and not correctable.

Where does maxixe Beryl come from?

Maxixe Mine, Minas Gerais, Brazil and Madagascar. Origin affects price, so we name the locality rather than the country on every quote.

Is maxixe Beryl hard enough to wear every day?

With care. It is 7.5–8 on the Mohs scale, which is hard enough, but imperfect basal cleavage means it can split if struck at the wrong angle. Use a protective setting and avoid ultrasonic cleaning.

How much does maxixe Beryl cost?

Indicatively Low and unstable — fades; not a commercial gem. Colour, size, clarity and origin move the price a long way within that, so treat it as a range and ask for a quote against a specific stone.

What is maxixe Beryl confused with?

Most often Aquamarine, Blue topaz, Blue zircon and Irradiated blue beryl. A refractive index of 1.578–1.584 and a specific gravity near 2.68–2.80 separate it quickly.
