Diamonds Discovered in Dayville in Eastern Oregon

Remember the song “Diamonds are a Lady’s Best friend”?

The white diamonds eroded out into pocket!

Most modern woman feel the current, cartel controlled, overseas “Blood diamond” pricing and corruption is not a friend; unless you are stupid, naïve, or never curious about the daily bad news around the world.

Diamonds are so rare on Earth that a South African Diamond supply was totally manipulated by a DeBeers Corporation since 1960s.

However, times and opportunities are changing!

Last Year, Russia timber fallers have discovered diamonds in Siberia and this new diamond competition alone should lessen the monopoly African De Beers Company has on diamonds brought to market.

One wonders how many marriages have broken a part or gone bankrupt over the initial excessive cost of the jacked up diamond ring alone these days.

The main cover photo here shows several varieties of the eastern Oregon rock types (Kimberlite) found by the author added to help you to find your own diamonds later.

2014 was the year Oregonians first discovered diamonds in Oregon’s Aldrich Mountain Greenstone District in eastern Oregon.

Now that the author has seen kimberlite AND diamonds here in Oregon, maybe they are elsewhere in this State?

Readers around the State can check out their area for hidden Kimberlite Deposits – with diamonds!

Comprises Josephine ophiolite of Harper (1980), ophiolites of Onion Mountain, Sexton Mountain, Pearsoll Peak, Rogue River, and Riddle areas (Smith and others, 1982) and Coast Range ophiolite and serpentinite melange of M.C. Blake, Jr. and A.S. Jayko (unpublished data, 1985). In southwest Oregon, locally includes small bodies of early Mesozoic or late Paleozoic serpentinized and sheared ultramafic rocks, mostly in shear zones. Locally, volcanic and sedimentary rocks shown separately.”

Actually, Jewelry diamonds used to be recovered exclusively from gravels around the world until 1960s and South Africans discovered the commercial quality, rock diamonds bake in – called “Kimberlite”.

The reason I tell you about a diamond discovery in Eastern Oregon is we Oregonians need more than one supplier to develop our own, local, fair Diamond market.

Maybe Oregon’s State office of Department of Geology and Mineral Industry (DGMI) should oversee and expedite such a diamond market exclusively here in Oregon for a world market and re-float Oregon’s schools and economy in the near future.

Here is how this all works.

Diamonds as tender

Rough Diamond Sales

“Once recovered, rough diamonds are sorted by experts in a controlled, secure environment, and categorized or grouped into parcels for tender. The rough diamonds are sorted into various parcels according to their shape, size, clarity and colour, and it is at this point that potential gem quality diamonds are separated from industrial diamonds.

Industrial diamonds are lower-quality stones which are not suited for gem purposes, but are suitable for use in various none-gem related applications due to overall characteristics of diamonds (IE; drill bits, cutting tools, medical devices, etc.).

Once sorted into appropriate packages, the diamonds are delivered to an accredited diamond bourse for tender in conjunction with various other producing mines goods. Tenders are typically held on a regular basis every four to six weeks depending on demand, and attended by the world's diamond buyers who purchase goods on behalf of their clients, or for their own use.

Traditionally in the past, the majority of diamonds were sold through De Beers' centralized selling channel, the Central Selling Organization (CSO), but it is now common for many companies, such as Diamcor Mining, to sell their rough diamonds to accredited diamond bourses and receive the best possible pricing.”

Thus, with more Oregon diamond suppliers, the entire State & world benefits!


OCCURRENCE OF PERIDOTITE – SERPENTINE IN OREGON is an online 1958 Department of Geology and Mineral Industry publication with maps showing where serpentine deposits occur in Oregon.

Thus, readers and their families can assess locally if they too have deposits of diamonds – the hardest natural mineral known today.

Still this old “Diamond” song still hangs around?'s_Best_Friend

"Diamonds Are a Girl's Best Friend" is a song introduced by Carol Channing in the original Broadway production of Gentlemen Prefer Blondes (1949), which was written by Jule Styne and Leo Robin. It was based on a novel by Anita Loos.”

Older, more docile, generations of American woman were more accustom to being considered as chattel by men or more cattle like trained and these gals could only hope for expensive admirer’s gifts, like a diamond. The modern woman is more independent and she really prefers to get gifts herself!

Can you imagine looking for diamonds is local gravels while cooling off during the summer heat? Its child play!

We harvest or placer diamonds; just like gold nuggets.

Never the less, a future new Oregon discovery of diamonds and market should make diamonds cheaper again with international and trans-continental competition again rising again.

Right now the author has only found 3/8th inch or smaller “Industrial” diamonds. Only one out of five kimberlite injection cones have diamond baked in them or four out of five are considered sterile with temperature and pressure not re-baking carbon enough to create diamonds.

Diamonds are crystalline carbon and the hardest known substance.

OSU diamonds

Diamonds are brought to the surface from the mantle in a rare type of magma called kimberlite and erupted at a rare type of volcanic vent called a diatreme or pipe. Kimberlite is a gas-rich, potassic ultramafic igneous rock that contains the minerals olivine, phlogopite, diopside, serpentine, calcite, and minor amounts of apatite, magnetite, chromite, garnet, diamond, and other upper mantle minerals. Upper mantle xenoliths are found in some kimberlite and provide clues to the magma's origin.”

The source depth for kimberlite magmas is estimated at 200 km, more than twice as deep as the source region for most magma. At a depth of 200 km the pressure is 60,000 times greater than the surface and the temperature is about 1500 C. Kimberlite magmas are rich in carbon dioxide and water which brings the magma quickly and violently to the surface. Most kimberlites occur as multiple intrusive events. Kimberlite was named for the rock associated with diamonds in Kimberley, South Africa.

Kimberlite magmas form "pipes" as they erupt. A tuff cone is at the surface and formed by base-surge deposits. In the subsurface, a funnel-shaped body narrows to a depth of hundreds of meters. The pipe (also called a diatreme) is filled with kimberlite, with or without diamonds (only 1 in 5 of the pipes at Kimberley contain diamonds).

Just how many diamonds are needed to make a pipe economical? Some South African mines operate at 25 carats of diamond per 100 cubic meters of rock or about 2 grams of diamonds per 100 tons of rock. Because diamond has a specific gravity of 3.5 grams per cubic centimeter”

What if a new diamond deposit was found and actually developed in Oregon?

Do we privatize it or join the diamond cartel or make it a gift to all Oregonians and humans, like our local world famous public Pacific Ocean beaches?

Further, the Scientific Report “Titanium-rich signature and textures of a kimberlite from Letlhakane Mine in Botswana (W. Africa) describes where these diamonds come from currently in another new central Africa discovery!

Once people out walking and knowing what kimberlite looks like will probably find many more diamond deposits in Oregon.

Our previous scientific report on Botswana is by these two British geologists, in 2005, describing the new African mine as:


As our Oregon cover photo shows, kimberlites pipes pieces lying on the ground vary in composition. Look closely at the cover photo showing geo-thermal tip or bubbly segment chocked full of Oregon diamonds. It is interesting that this kimberlite found is carrying mostly white milky diamonds with occasional industrial size clear, red and yellow small rounded diamonds. Actually, these orbicular white holes show where the diamond set historically before eroding & dropping out to collect these small billion year-old individuals.

These two British geologists, in 2005, describe the small rounded diamonds as “Pelletal Lapilli”!

Most people encounter these small diamonds before digging deeper to find larger commercial grade diamonds & potential wealth. These two British geologists, in 2005, describe the new African type of diamond a “probable monticellite” – if you want to look up more details later (GEOPHYSICAL RESEARCH ABSTRACTS, VOL.7. JAN. 2005).

These two British geologists, describe the new way to look for “Kimberlites”

Early African geologists had to discover these clues in 1960s to discover their huge diamond deposits slowly being exhausted today; but they would not share diamond-discovery clues back then. They wanted a monopoly.

Most of the kimberlite examined is massive volcanic – clastic (NOTE-Bubbly), whilst rare layered volcanic-clastic and magmatic kimberlite is also present (NOTE dense black lava types in our Oregon photo)

The kimberlite is characterized throughout by predominant basalt country rock fragments and xenocrysts of Olivine (commonly serpentised), with rarer garnet, phlogopite (NOTE: copper Mica), Ilmenite (NOTE Titanium ore) and chrome-diopside xenocrystst.”

In closing, some readers may remember or are familiar with the term “White Diamonds”; thanks to another actress, Liz Taylor.

Liz Taylor does show how to do better on a new venture!

  • How Elizabeth Taylor's White Diamonds is still the best-selling celebrity fragrance of all time - 20 years after it first launched
  • Elizabeth-Taylors-White-Diamonds-best-selling-celebrity-fragrance-time.html
  • Follow-up perfumes, which include Diamonds and Emeralds, Diamonds and Rubies and Black Pearls, also continue to enjoy retail success, with sales of $76.9 million last year.”

“With no major acting work in the last 10 years the star's fragrance sales enabled her to give generously to charity and maintain her lavish lifestyle. One of her last Twitter posts read: 'A special thank you to Geary's Beverly Hills who continues to carry my Elizabeth couture jewels.'

The cover photo actually shows Kimberlite impregnated with round orbicular, classic white diamonds found in a dry ravine in the Southfork of the John Day River this summer.

Oddly, there are various colors & forms of Kimberlite up the Southfork (see cover photo) shown for my reader’s personal self-benefit. The author assumed it would only be coal black or serpentine green. Rather, think of Kimberlites like a huge vacuum tube sucking up whatever is below it – below the EARTH’S mantle and injecting it into the de-pressurized open air or Earth’s surface. Crudely, it could be compared to a popped pimple on the face?

The author has always picked up odd looking rock as tokens of what the subsurface geology is. He collected jigsaw pieces out hiking; as he wanted later to examine these rare stones as a piece of the puzzle we see around us every day. Sadly most humans have no clue what is a “keeper” gem or a “Leverite (Leave it right there)” The old gold miner rarely had a clue. like a monkey, he often mimicked what neighbors were doing. Diamond mining ventures are relatively a new thing on Earth.

Most rural people would not know sand from diamonds!

My regular readers know that I have been slowly putting the South Fork geologic together as personal local prehistoric river drainage. Frankly, the Author never had seen former diamond beds before this summer. The Southfork has serpentines and associated soap stones and jades; but I literally stumbled upon the much harder and older, hidden diamond-bearing kimberlites.

Do all Oregon serpentine or greenstone stripes all across our state have diamonds?

Like most I assumed prehistoric forest buried as coal was the carbon to make pure carbon diamond; but all the diamonds chemically dated predate even life on earth. We are talking meteorites or melted earth making diamonds!

All diamond individuals are billions of years old and come from some “Prehistoric Graphite” still under scientific investigation and debate.


“Diamcor defines Primary Kimberlite Projects as any diamond project which involves the exploration for, or underground mining of, any new or existing kimberlite source, these areas being the primary source where diamonds originate from.

Although this type of exploration, and any such resulting project, could provide an extreme economic benefit to Diamcor in the long-term, primary kimberlite diamond exploration is accepted to be an inherently high risk proposition which requires the commitment of significant high-risk capital to support the ongoing economic evaluation needed. Associated long lead times of five to seven+ years to production are typical, as is capitalization into the hundreds of millions of dollars, and these efforts currently fall outside the primary scope of Diamcor's current near-term focus.

Our initial involvement in any such projects may occur should we acquire other projects and then discover new kimberlite pipes or blows of interest on those properties. Should this occur Diamcor has the ability to perform initial exploration efforts to define the potential significance of such a find, after which it is anticipated any warranted additional efforts would be completed in conjunction with a suitable larger joint venture partners in order to offset associated costs and minimize risk.”

Oregon Lottery dollars could initially help Oregon’s inventory of diamond assets and fund the set up an Oregon Diamond Market (ODM!) for a better world tomorrow!

This could be a great current governor’s campaign issue!

We Oregonians do not seem to demand much of our elected governors to help us voters specifically get ahead and our State economy moving ahead again.

Think! An Oregon discovered diamond could really be a girl’s best friend again. Plus, “No more “blood Diamonds” in our corrupted world.

It is remarkable to collect your own Oregon diamonds!
