The facts
What laguna Agate actually is
The species behind laguna Agate is chalcedony (agate), SiO₂; it forms in the cryptocrystalline trigonal system.
Fine iron-oxide banding gives scarlet, coral and white; tightness of banding is what commands the price is responsible for the colour — and the chromophore, not the name, is what decides whether a colour is stable.
On the instruments it reads a refractive index of 1.530–1.539 and a specific gravity of about 2.58–2.64, with none cleavage.
Where laguna Agate comes from
Commercial material comes from Ojo Laguna, Chihuahua, Mexico and Estación Ojo Laguna, Mexico.
Different localities give different colour and different clarity, and the trade prices them differently. We state which one.
How laguna Agate is treated
Untreated — the value of Laguna agate rests on natural colour and pattern, so dyed or heated material is a serious fraud risk in this name. Heat-reddening of pale nodules does happen and is difficult to prove.
We state the treatment on every stone, including when the honest answer is that it cannot be determined. A treatment disclosed is a fact; a treatment discovered later is a refund.
What laguna Agate is confused with
Watch for Crazy lace agate, Condor agate and Dyed Brazilian agate — these are what turn up sold under this name.
The separation is rarely a matter of opinion: refractive index 1.530–1.539 and specific gravity 2.58–2.64 settle most of it in a minute, and magnification settles the rest.
What laguna Agate is used for
The trades that buy laguna Agate are mineral collecting, jewellery and decorative objects. They do not want the same thing, and they do not pay in the same unit.
We quote each application in the unit that trade actually buys in, by the specimen, by the carat or by the piece.
Durability and care
Hardness 6.5–7; cleavage none. That combination decides what it can safely be set into.
With no cleavage plane to worry about, the practical limit is abrasion rather than breakage, and it takes daily wear well.
Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.
What laguna Agate costs
Expect roughly Fine rough 100–600 USD/kg; top display faces well into the thousands, depending on quality.
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 laguna Agate treated, and how?
Untreated — the value of Laguna agate rests on natural colour and pattern, so dyed or heated material is a serious fraud risk in this name. Heat-reddening of pale nodules does happen and is difficult to prove.
Where does laguna Agate come from?
Ojo Laguna, Chihuahua, Mexico and Estación Ojo Laguna, Mexico. Origin affects price, so we name the locality rather than the country on every quote.
Is laguna Agate hard enough to wear every day?
Yes. At 6.5–7 on the Mohs scale with no cleavage plane, it handles daily wear well. The practical limit is gradual abrasion rather than chipping.
How much does laguna Agate cost?
Indicatively Fine rough 100–600 USD/kg; top display faces well into the thousands. 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 laguna Agate confused with?
Most often Crazy lace agate, Condor agate and Dyed Brazilian agate. A refractive index of 1.530–1.539 and a specific gravity near 2.58–2.64 separate it quickly.
What is laguna Agate used for besides jewellery?
mineral collecting and decorative objects. Each of those trades buys it in a different form and a different unit.
