The four most important factors that determine the value of a diamond are cut, clarity, carat weight and color.
Natural Diamonds
These are the most traditional, naturally occurring diamonds. Their clarity and colour qualities are unmatched and they are usually the most expensive types of diamonds.
Lab Grown Diamonds
With advancements in technology, we were able to create diamonds in laboratory situations. They have a benefit over natural diamonds since they are up to 50% to 60% cheaper than natural diamonds with experts predicting that they might rise up to 75% cheaper.
Treated Diamonds
A diamond that has been mined naturally but enhanced or manipulated in a lab to enhance its cut, clarity or color in a lab is known as a treated diamond. They are drastically cheaper than natural diamonds.
Natural Fancy Color Diamonds
These are extremely rare (1 in 10,000) natural diamonds. Hence, they are incredibly expensive. They come in a huge variety of colors with pink and yellow being the most popular.
