What items are similar to those sold online on sites such as eBay?

Are there potential buyers for the product?

We also have to consider the current market prices for the product. Silver and Gold prices, for example, will fluctuate throughout the day.

The value of diamonds and precious metals like gold and silver is largely determined by their quality. Diamond merchants use the combination of cut, color, clarity, and carat, known as the 4 C's, to determine a diamond's value. Similarly, Platinum, Gold, and Silver values are determined by their purity. The open Market sets the price, as shown above, while quality determines the value.
