Gold is very soft, almost useless for most engineering purposes. Diamond OTOH is the hardest substance known to man.
That depends on your point of few. If you simply want the hardest gold, then 10k gold is what you're looking for as it certainly is the hardest. However, if you're looking for a durable gold item but with a higher actual gold content, then 18k is your choice and it has a beautiful warm color. In America, the favorite karat of gold is usually 14k followed thereafter by 10k. Bill Warren www.hudsongoldmine.com
