I've been doing extensive research regarding lab diamonds, moissanites, and cubic zirconia. This purely based on the amount of sellers advertising lab diamonds in gold and silver plated jewelry. According to research, it's a fact that authentic diamonds and lab diamonds have almost the same value, lab diamonds having enhanced clarity and colour. Flaws are also filled to make them more pure. But they are still diamonds. They are also only set in pure white gold, platinum and yellow gold. Moissanites can also be tested on a standard diamond tester, like authentic and lab diamonds, as they have the same composition. Cubic Zirconia and simulated diamonds are one and the same thing. They are man made, The one being a slight better quality than the other. CZ's are more often used in the cheaper range of costume jewelery, lab diamonds also in costume jewelery and sterling silver. As pure gold and platinum are very expensive materials, authentic stones are preferred. In cases where very high quality simulated diamonds are used, like the new Russian Simulants, gold and silver settings can be used. These new simulants are scratch-proof and can even cut glass, have the same cut and clarity as authentic diamonds, can now be set in solid gold or sterling silver. If there are any gemmologists on the site, please assist with this topic as there are many misleading ads as to stones being advertised as lab diamonds when in fact they're cz's. Maybe you'll have a tip or two for the other Bobbers?
