A general rule for pricing diamond rings is that as the diamond's weight increases so will the price. And while this is true, there are also a variety of factors that can affect the cost of a lab created diamond ring.
The shape of the diamond and how much rough diamond was maximized in cutting the shape can determine how expensive the diamond will be. For example, round brilliant diamonds are the most expensive diamond shape, not only because they are the 'standard' cut as outlined by the Gemological Institute of America, but because they also create the most diamond waste of any of the shapes.
When compared to fancy-shaped diamonds such as radiant, princess, or oval-cut lab grown diamonds, of similar carat weight, the round diamond will always be more.
Another factor that determines the cost of the diamond ring is how your chosen diamond is graded in the other 4C categories of cut, color, and clarity. The higher the diamond scores the rarer and ultimately, more expensive, the diamond will be.
Finally, a lab created diamond engagement ring will be priced according to the precious metal utilized, yellow gold vs platinum for example, and the style of engagement ring, as seen by classic round solitaires being often priced less than halo settings.
