Hey All
Does anyone know anything about "Sea Sediment Jasper" or "Emperor Jasper" ? I'm starting to see alot of both materials but always in finished jewelry,never in rough.Both have really neat patterns and colors which makes me skeptical...ecspecially when I can't find any solid facts or descriptions on how either is formed from a trusworthy source.

Hey Phil,

I had never heard of Sea Sediment or Emperor Jasper, so I Googled them. The vast majority of what I saw appeared to be dyed rock in a wide variety of unatural colors.

Hello Phil,
Sea sediment jasper appears to be a low grade of material found in Australia. The high grade material in a unique green color is often referred to as variscite. I haven't tested any to make sure it is variscite or not. A lot of the lower grade material has been dyed and possibly stabilized. Lots of garish colors involved. As to Emperor Jasper, the name is being applied to several different materials that range on color, etc. i won't comment more as i amnot sure wich Emperor Jasper you are regerring to. Oh the joy of lapidary material being slapped with any old moniker that pops into someones head for marketing purposes. You have to call it something so why not anything.
Best Regards,

Hey Mike and Al

The one is actually called Emperor Stone but either way that's pretty much what I was thinking...Enhanced.
Well I'll just stick with the natural stuff the way the good Lord made it!

Hello Phil,
I had to scoot out the door for a while. I was going to add that some of the sea sediment material may also be going under the name Aqua Terra jasper. I have hardness tested a piece of this stuff and jasper it is not. Check out to view the beautiful green material I truly believe to be variscite, especially the spiderweb material that gives me reason to suspect the names sea sediment and aqua terra. I haven't seen any material looking like these called Emperor jasper. I have seen some banded material of chrysocolla and limonite matrix called Emperor "Jasper". Jasper is really getting worked over as a nameately. I have seen sodalite called sodalite jasper as well as some other misuses of the the name. I think some of the Chinese dealers believe jasper and rock are the same word.

Hi Al

Thanks for the Link, The Webbed Variscite is amazing!
I see it is priced accordingly also!

Have a good one.
it appears to be some sort of dyed material...I've heard different claims..that it is something man made with some variscite mixed it to that there is something similar used to make tiles that is literally seabed sediment and it can be easily dyed. The thing that annoys me to no end is that it has gone from being called Sea Sediment jasper to things like variscite jasper to now being marketed without qualification as 'variscite', imperial jasper, turquoise and other real stones.....and while some of it is sort of the color of variscite, they are also selling it in pinks and purples and multicolored conclomerate colors!

Ask any mineralogist and they will inform you it is still just a man enhanced "rock".  Just because someone sells a rock and attaches a fancy name to it does not make it a mineral.  "Pet Rocks" have many names, given by their owners but they are still just nice rocks.

  I'm sitting in front of my PC and listening to my Irish music collection, 48 hours and counting of Celtic music.  Reading how people name rocks to enhance their value brings a chuckle to my weary mind and is quite pathetic that it continues to be associated with rock collectors.  People take "Leaverite" and put a fancy name on it so they can foist it off on a mind beleaguered group of "Lemmings"!! 

  Up the "Tullamore Dew" and long may it enhance the brain cells.

I see Glen Archer every year at Tucson. I have never seen any of his material that appears to befake. That doesn't mean its not so it's just my observation from looking at (and buying) his material.

I was browsing eBay for cabs. While you can find some awesome pieces for pretty cheap auction prices you see a lot of this so called brightly colored "sea sediment jasper" they are quite pretty and extremely cheap on eBay so if you would like a cab or two but don't want to pay natural rock prices that is where I suggest finding them. What about dragon veins agate. Is it man made? If it I just dyed what is its natural color?
Al O
Hello Tiffany,

Most of the material called Dragon Vein jasper is low grade white chalcedony that has been heated and rapidly cooled causing it to crack. It is then sealed and dyed various colors.

Best Regards,
Al O
It is a cultured material and never did claim to be any real mineral, just a fun and cool stone for collecting and creating jewelry. I have several pieces and love them, real or not..!


Sea sediment jaspers are precious stones, very often in shades of blue, and are found in the Asiatic regions. Jasper was a favorite gem in ancient times and is mentioned in Hebrew, Latin and Assyrian literature. The name jasper is derived from a Greek word that means spotted stone.

Pyrite and Rainbow Sea Sediment Jasper make up totally unique stones. Specs of pyrite are seen throughout the in the stones. The Elements of the Earth are represented in the metallic hue of these irregular stones of sea sediment combined with pyrite. Colors are usually interspersed throughout and are deep toned.

Sea Sediment Jasper is only one of the names for these absolutely gorgeous stones that are also referred to as: "Aqua Terra Jasper" (the blue & green colors), "Impression Jasper" (for it does make quite the impression), "Snakeskin Jasper", as well as "Variscite" and "Regalite" and “Sea Sediment Jasper Pyrite”. This stone has proven to be somewhat of a mystery. We know that it is a natural jasper material from Africa that has a somewhat jelly-like luster resembling Natural Turquoise-- but no one in the market knows what exactly to call it yet!


Jasper is a fine-grained chalcedony and comes in all colors. The name jasper comes from the Greek and means "spotted stone." Aqua Terra (Water and Earth -- the blue & green varieties of Sea Sediment Jasper) is a wonderful stone for helping one find inner peace, clarity, love and compassion, helps with the alignment of the physical and "Light" bodies and is an excellent stone for emotional healing.

I really cannot accept that he multicolored sea sediment jasper with pyrite is a natural stone.

First, all the colors are those most associated with material that has been artificially dyed. Then there is the problem that all the colors occour  together. Then toss in the pyrite that looks fractured as if brecciated. If the pyrite was natural authigenic material it shouldn't have this brecciated look. I do believe this is a lot of different crushed material that has been dyed and then cemented together. I know some of the colors run with cleaners such as acetone. I haven't subjected any of it to a flame test to see if a bonding agent starts to burn off.

OK by me if you like the stuff but I can't consider it natural considering how much alteration it has undergone.

As a geologist, I was taught that jasper is a member of the quartz family as one of the cryptocrystalline varieties. Some consider it a form of chalcedony. It is coarser and contains more impurities than chalcedony. Due to the impurities jasper is often more opaque than chalcedony. As such some people classify it separately from chalcedony. Usually I refer to jasper as being a cryptocrystalline material separate from chalcedony for these stated reason. However we must remember that all the definitions for the cryptocrystalline quartz varieties aren't as rigorous as the definitions for accepted mineral species. All varietal names should be used with caution because their definitions are not concise and no overseeing professional group monitors them for consistency. This also opens the door to anyone attaching a name to just about anything for their own marketing purposes. And sometimes those purposes are deceptive. Caveat emptor.

you all mcrockers, crack me up.

  Biggs jaspers, the colors are from sea floor sediments an Fiona an fauna  life forms.  and dead sea / organisms   / geothermal smokers.  minerals sediments.

Hi from across the pond,
I make pretty things out of (mostly) semi precious stones. My favourite supplier was offering free postage in January and I went for the heavy stuff.

Only my neighbours have seen the new Regalite line and they LOVE it. That’s the good news.
The down side is I couldn’t find out much about it from a source I trust. I didn’t even know what colour it is before it hits the dye vat...surely that day-glow orange couldn’t be natural !?!
My customers are used to asking questions about the stones they get from me and I was a bit nervous about displaying these beautiful stones in a total state of pig-ignorance.
Thanks to you ladies and gents, I shall put them on the fun side of my jewellery display labelled as
Moggie Stones (conglomerate(?) of questionable pedigree).   (Moggie is British for a stray cat.)  A conversation piece at least.

Jasper is a sedimentation formation,  MUD. sediment  from many forms of earth phases of past.  Remember the    

K.I.S.S. / Keep - it - simple - sediment  ......

Payday is on Friday and you know what flows down hill, MUD

Good to hear their is bad wording for salesman ship in the trade.

 my favorite word is,   black onyx,  word charge to sale cheap black jet rock in the 30s......----   Onyx meaning, Layer on layer / sounds like a sedimentation formation....... The Egyptians coin the word Onyx  layer on layer Like Sard Onyx  silica  layers.

Blue lace agate is a onyx formation.

To many to list. 


Hello All

I have been reading everyone's comments on Sea Jasper.  I bought some from a dealer and it is so, so pretty.  It is extremely lightweight.  However, when I was setting one in a pendant tray, I cracked one. So  I broke it a part and it is in very thin layers of some materiel. The pyrite looking part it felt like a foil of some type and the rest felt like chips all compressed together.

Even though this is not a real stone, rock it is very, very pretty for jewelry making. I attached a photo with this. I think this is what most are talking about.

Just purchased my first piece of sea sediment jasper.Fossiked in Murchison Victoria. Cut and polished in Murchison Victoria Australia. This stone is turquoise in colour with veins of dark brown sediment and a lighter brown running through it. I purchased it privately and also saw pieces of raw material waiting to be tumbled. This stone was straight out of the ground .. pure .. natural .. and the shades of colours were beautiful. Untampered with .. stunning. My piece which was cut in a heart shape .. polished on front .. raw on back cost $18 .. drilled with ring. Not expensive .. but stunning. I would catagorise this piece as AquaTerra Jasper. .. and remember .. MOOKAITE is a form of jasper unique to Australia.
