Today we shape rock and gemstones using abrasive scraping techniques. Scraping and grinding are the same process of material removal. Hard material scraping away softer material. We grind material down into flat planes using a high speed rotating diamond impregnated discs or laps.
Flat lap pictured below can make flat facets or planes. Additional attachments allow for concave faceting.
High speed rotating core drills (below) can scrape down hard material in a circular formation only.

Today, our technology in lapidary allows us to make flat and concave facets as shown in this awesome 54.93 carat Combination Cut Amethyst, Quartz created by John Dyer. (Amethyst pictured below)
The play of light in this Amethyst by John Dyer is mesmerizing.
Diamond coated ball burrs can create concave indentations.
Grinding concave indentations into the back of the stone allows for optical illusions as shown in this well executed 22.46 carat Blue Topaz created by John Dyer.
Round drill holes can be made with a diamond drill or by sonic drilling.
Below, Andrew Gulij creates this internal kaleidoscope of inner beauty in a Citrine, Quartz by drilling the back of a steep angled pavilion (refraction purposes). Each empty drill hole is then inserted with a gemstone rod. Gemstone rods inserted in Citrine (below) are: Calcareous Coral, Turquoise, Lapis Lazuli, and Malachite.
The astute gem cutter knows the critical angle of each crystal and uses that knowledge for directing internal reflection and refraction (bending of light). The result is an internal explosion of color in motion as the stone is in rotation.
I use the best gem cutters residing in America when I design! Made in the USA!
The equipment used today can only make flat exterior facets, curved facets, rounded curves, and rounded indentations.
What about square, triangle, and star holes?
Geometrics allow for more freedom in designing and would place the creator second to none and most definitely unique.
Sound technology makes geometric holes in stone.
Following in the footsteps of our ancient ancestors, I am using the same sound technology used at the ruins of Egypt (round and square sonic holes), Puma Punku (geometrics holes in Andesite), Norway (star holes), and California (star holes).
(above left) Norway and (above right) Monson, Massachusetts star holes in stone (Granite).
No one in the world today can create a perfect geometric hole in a crystal or rock aggregate.
(Above) A 6mm 5-point star hole in a Pink Tourmaline cabochon.
The star hole was created with the help of a fabricated star shape metal tube.
The steel star tube cannot drill through the crystal alone.
It must be accompanied with energy, frequency, and vibration. This is the same sound technology used thousands of years ago by our ancestors.
And is so much fun!
The initial weight of the Tourmaline cabochon weighed 17.185 carats.
The weight of the Tourmaline after drilling out the star hole is now 16.355 carats (weight includes the star core)
The material Tourmaline loss after drilling is 0.83 carats (under 1.00 carat loss). That is AMAZING! Below shows small nicks along the star hole perimeter and along the star core (caused by microscopic explosions of abrasive media via Sympathetic Destruction).
As the star tube pushes its way through the tourmaline crystal it leaves behind a star hole and core.
Along with the Pink Tourmaline, I drilled a star hole in crystal Quartz (Pictured below)
The rectangular cut and polished Quartz has beautiful dendritic internal mineral landscapes. Anytime a mineral grows in a tree-like or branch-like formation, we call it dendritic.
The 6mm star hole missed most of the dendrites. You can see a tiny bit of Pyrolusite on the star core (pictured above)
The branch-like mineral within this quartz is a manganese oxide called Pyrolusite. The small areas of light brown within the dark branches is an iron oxide, possibly Limonite.
