Lab-grown diamond by HPHT

Our first synthetic diamond by High Pressure and Hight Temperature (HPHT) ! (aka 'Lab-grown') . As gemologist working for a gemstone testing 'Lab', i would actually prefer to call them 'Factory-grown' ! What's wrong with 'Synthetic' anyway ? In these pictures : typical 'Stop-sign' tension pattern and metallic inclusions.
