Clarity & Cut

Inclusions in natural coloured gem stones are a positive sign to differentiate them from man-made materials. Clarity of a gemstone is one of the price determining factors, alongside with colour, cut, and carat weight.  Normally in a fine gem inclusions are not visible to the naked eye. In cheaper stone inclusions can be obvious from a certain angle.  We photograph all stones from different angles with no editing to show the maximum interior. However, you may reveal more internal features when you study the stone thoroughly. Having said that, the closest to seeing the real gem would be a video, so you can always request us to offer a short clip under natural light to help you decide better.
