When you invest on jewelry you pay for the raw gold plus labor. When you want to sell the jewelry piece, gold buyers will  pay based on the value of the gold not the labor put into it. Especially, during periods of increased gold prices, production costs for jewelry manufacturers rise and force industry operators to either incur lower profit margins or raise the price of goods (gold plus labor). Most will choose to increase the price of goods which creates more demand, this allows them to take advantage of the increase in demand without losing anything. Gold investors put as much as they can towards raw gold like bars, coins, or scrap, and stay away from any alternates like jewelry or finished goods. They want to only play for the raw gold and not any extra characteristics of the piece like labor costs. This guide is meant to point you in the right direction to when you want to sell your gold or buy gold.
