Rough textured gold is found not far from its source. However, people like to wear fairly smooth and flat nuggets which don't snag or tear clothing. Thin nuggets are preferred by most jewelers because their reduced weight costs less and they appear to be larger. Del and his wife, Gail, have mined on Gold Dust Creek near Circle, and at remote locations in both the Alaska and Brooks ranges. The finer stuff is used for bezels and gold settings around gemstones.
General overlay uses grains to small oatmeal-flake gold.
Anything over one ounce is too heavy. I don't wear the heavy watchband stuff, either. The last 10 years I haven't recovered many nuggets above one-third ounce. Since dealing with individual sales to jewelers takes a lot of time and usually involves small volumes, we now send all of our gold directly to the refiners. Supporting this is evidence that gold in a dissolved or colloidal solution makes nuggets from a gradual process of accumulation and compaction.
