On rare occasions however, gold can be found in crystalline forms, which are very rare and highly collectable. Gold specimens of rough texture that contain quartz and other host material are also occasionally found by prospectors using gold pans, sluice boxes, and metal detectors. Gold is one of the most sought after elements on Earth.

Many quartz veins, especially those with gold, are in such close proximity to granitic bodies that other sources are rarely considered. Yet, in Arkansas, where we have the greatest concentration of collectable vein quartz in North America, no granitic rocks have been discovered associated with the deposits.
While the surge of solid quartz countertops is likely a response to the excess of busy, speckled granite we saw everywhere in the early 2000s, we''re now seeing a shift back toward center with the rise of countertops featuring less densely packed color variation. The color—which appears in the form of veining that contrasts against the main shade of the stone—is more random and larger in ...
Gold And Quartz Specimens. This page is dedicated to the gold that''s still attached to quartz, or a host rock. This type of gold is highly desired in the mineral collecting community. Gold/Quartz specimens are in a completely different league of their own. Remember the specific gravity of quartz is times heavier than water, whereas pure ...
Quartz veins, indicated by the red lines, formed between and within the layers of rock. This heat caused hot, quartzrich fluids to ooze through the folding rocks, dissolving and concentrating gold. As the hot quartzrich fluids cooled, gold was precipitated out into quartz veins.
If you haven''t seen the look of quartz surfaces in the past few years, you are missing out.. Quartz counter surfaces have come a long way from that pebbly look that many people know.
