Before and after recutting

My priorities are, best brilliance first, then biggest possible dimension
and last but not least weight retention.

All the below gemstones have been recut, because their beauty was compromised through a less than optimum cut. They where either faceted for weight retention, or on old faceting machines or on machines which do not permit to read the faceting angles or by inexperienced faceters, or a combination of all above.

See for yourself the difference after the stones have been recut. Only now do they reveal their beauty and show the true nature of a gemstone.
