It depends on how pure you want it to be, and what you want to do with it. If, say, you are looking for a cheap source of water-soluble boron (for mixing into a formula for killing ants), you can probably pick up a 2 kg box of "20 Mule Team" Borax for about US$2.00 at your local supermarket. Borax should be about 11 % B.
You could probably buy a small bottle of Boric Acid, U.S.P. (a compound meeting all the
purity tests specified in the United States Pharmacopeia) for about US$5.00 at your local pharmacy. Boric Acid is used (diluted in lots of water) as an eye-wash for sore eyes, and the Anhydrous (without any combined water) Boric Acid should be about 17 % B.
If you want the C.P. (chemically pure, "technical" grade), 99.0+% elemental B, 1 g is
offered for sale at US$30.00 here:

Using the Chemical Abstracts Service registration number for Boron, CAS 7440-42-8 to search may help you find a better deal for your purposes.
If you want really, really, really pure Boron, similar to the purity of Silicon used to make
computer chips (before they are "doped" with tiny traces of other elements in specific places to make the transistors), you may be able to find a source who will make it for you for only a few US$100,000.00. Getting the last few impurities out of anything -
even a large single crystal of an element - becomes ridicuously expensive. Any sample of Boron big enough to see will have many atoms of other elements as impurities - most likely a layer of Oxygen from the air on the surface - even if it is "high purity".
What else can I help you with?
How much is a pound of boron worth?
the average cost of crystalline boron is $5/g.
Is boron is shiny?
Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.
Is boron a pure substance or mixture?
Boron is a pure substance. It is a chemical element with an atomic number of 5 and is found in nature as a solid.
Is boron malleable ductile or brittle?
Boron is considered brittle in its pure elemental form.
What is the cost of boron per oz?
The cost of boron varies depending on the purity and form of the boron compound. Typically, boron can range from $4 to $10 per ounce.

Boron is a pure substance. It is a chemical element with an atomic number of 5 and is found in nature as a solid.
Is element boron a pure substance?
no
What is boron's pure element form?
The "pure element form" of boron is a meteorite. Boron isn't very reactive...but since it's formed by cosmic rays it isn't very abundant either.
Is boron malleable ductile or brittle?
Boron is considered brittle in its pure elemental form.
What are the chemicals of boron?
Boron is a pure element with symbol B and atomic number 5.
What is the cost of boron per oz?
The cost of boron varies depending on the purity and form of the boron compound. Typically, boron can range from $4 to $10 per ounce.
What shape is a pure boron molecule?
A pure boron molecule typically forms a planar triangular structure, known as a borane cluster or boron sheet. These structures can vary depending on how many boron atoms are present and how they are arranged, but they generally exhibit a flat geometry due to the sp2 hybridization of boron atoms.
What is the correct formula for boron?
Boron is an element, #5 on the periodic chart....so the formula then for pure Boron would be its chemical symbol "B."
How do you make a pure sample of boron?
One method to obtain a pure sample of boron is by reducing boron oxide with a metal at high temperatures. Another method is through the electrolysis of molten boron compounds. Purification processes like sublimation and distillation may also be used to achieve a high-purity boron sample.
Is boron shiny or dull?
Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.
