Gemcutting

The quality of cutting is often overlooked when pricing a colored stone unless it is a native cut. However, a precision cut gem will always present a far brighter and more desirable appearance than is observed in an average make. Precision is cutting is always worth the extra cost and a premium must be considered with pricing such a stone using the GemGuide.
