Gold-plated describes jewelry with a layer of at least 10K gold bonded to a base metal. Gold plating eventually wears away, depending on how often the item is worn and how thick the plating is. Each factor affects the price. Make sure you know how a particular scale and grade represent the color of the diamond you're considering. Know the difference between laboratory-created gemstones and naturally mined stones.
Stones created in the lab are visually identical to stones mined from the earth.
But, because they look just like stones mined from the earth, they must be identified as lab-created. If you want a naturally mined stone, ask if it has been treated. Treatments also may affect the stone's value. If you're buying a watch, determine whether you want one that runs on a battery or one that must be wound daily. Ask if a warranty or guarantee is included, how long it lasts, and what parts and repair problems it covers.
