Dendritic Gold: Gold that “grows” in delicate almost fern like branches.

DENDRRITIC

Crystalline Gold: Gold that is crystallized with thousands of minute crystals that can be seen under magnification.

CRYSTALINE

Crystallized Gold: Gold with geometric crystals visible to the naked eye. Very rare

CRYSTALLIZED GOLD

Leaf / Foil / Plate Golds: Gold that grow in thin to extremely thin sheets usually very shiny but not always. I know some will disagree with me but these golds look similar to each other except for thickness essentially.

FOLDER LEAF

Octahedral Gold: Gold growing in octahedral crystals similar to diamonds this is the most common form of gold crystallization.

Trigon Gold: Gold crystals in a pyramid or triangular 3d shape. This is the second most common gold crystallization.

Wire / Rope Gold: Gold that grow in the form of thin wires or thicker “ropes” This is an extremely rare gold formation and highly prized by collectors

WIRE                      WIRE NEST               

Hopper Gold: The second most rare gold formation and again very highly valued by collectors, usually starting in the hundreds per gram!!! Hopper gold is gold that forms step like structures otherwise known as chevrons. Trigon crystals are the most common type of crystal that will show hoppers.

HOPPER

Flakes gold: piece of chipped gold pieces.Found after shredding.sometime can be found around fool's gold.Therefore best to stay away from this form.

GOLD FLAKES
Cubic Gold: And last but certainly not least! Cubic gold formations, the must have for any serious collector, this is the absolute rarest form of gold crystal even very small specimens are highly prized larger ones selling for obscene amounts of money in excess of $2000 per gram!!!

ALLUVIAL GOLD NUGGETS
are nuggets that are found in creeks which has been tumbled off many years ,so they are smooth appearance

A SPECIMEN GOLD NUGGET
are nugget that are matrix both gold and stone. In Australia it has been found with quartz and/or ironstone.Larges piece found ,was found in 1872 - " Holterman Nugget" weighting in as 630 pounds(250 kg) Note this is not a nugget (as nuggets are 90 to 100% pure gold, this is mostly ironstone/quartz , question is how much gold was in it.This gold piece was melded down.

DOLLYPOT GOLD
This is my friend not natural gold - what you say ? Well its crushed gold ,it contains very minor  impurities - silver etc.

   Believe it or not that is not the full list of types of gold crystals that mother nature creates but that will do for now. I hope this article has given you a greater appreciation for the natural beauty of gold specimens, a beauty no jeweler could ever replicate.

ok i'm new at this but after many hours surfing around , i found that when gold is mixed with other alloys the colour is changered from a bright yellow gold ,down all the way to a white. so lets break's it down a little.

nice bright yellow - 100% gold

white gold - 90%- 70% silver 10%-30%% gold ---

whitish gold  - 70% silver 30% gold - sometime copper gets mixed in to which up to 30% which takes 15% of gold and silver away.

pale green yellow - 30%-40$ silver  ,30%-60% gold and copper 30% to 40%.

green yellow - 30 to 15% silver ,70 to 85% gold and copper 30 to 40%

yellowish - 75 to 45% silver, 30 to 70% gold and 40 to 50% copper

yellow - 40 to 5% silver ,60 to 95% gold and copper 40 to 50%

reddish - 90 to 70% gold, and copper 50 to 70%

red yellow - 5% silver, 95 to 90% gold and copper 45%

copper red -70% gold , and copper 70%

please note that its up to , as i to can see that some doesn't add up to 100%

just picture that its a triangle with gold at top , with silver on one side and copper on the other --the more white the more silver , the more reddish the more the copper.

now with prices white gold and red gold show be cheaper ,as its got less gold, the brighter the colour the more gold and more of a price.
now this is to weight

but collectors go by looks

a flat piece would be priced by weight , as for a nugget that looks like something eg. a ducks head( yes that duck's head again ,i missed out on , so pissed about that one)..say the nugget was 0.20 grams - worth around 6$ ,cause it has a nice shape (duck's head) the price would double. i believe this piece jumped up to 25$ , not bad for a 6$ nugget.

i anyways go for the shaped nuggets that look like something eg, head ,tree(some gold wire can look this way) anything that got a good shape.

i been collecting for 6 months now and upto 1/2  an ounce and its still growing
with help from this site and many others ,my love for gold has growing.

if anything in  document is wrong just p.m me and i will fix the post
thanx michael
