If it just bothers you for some reason to have a diamond that was created rather than found, then spend the extra for a natural diamond. Sometimes they are referred to as certified diamonds, which just means that they've been inspected and their flaws documented.
- Simulated diamonds are also known as diamond simulants and include things like cubic zirconia (CZ), moissanite, and YAG. They can also include some natural clear gemstones like white sapphire, white zircon or even clear quartz.
- Synthetic diamonds are also known as laboratory-grown diamonds, laboratory-created diamonds, cultured diamonds, or cultivated diamonds. They are real diamonds but not grown by Mother Nature.
It is obvious that real diamonds are much more expensive as compared to simulants. You could probably buy a simulated diamond for a fraction of the cost of an actual diamond.
