|01 ||The rough Chrysopras has been sliced and a center hole was drilled.
||02 ||Thikness about 1.5 cm.|
|03||A large silicon carbide wheel served to shape
||04||a rough preform,|
|05||and to separate front and back petals.
||06||The individual petals are roughly modulated.|
|07||The next step is done on a large diamond wheel
||08||as demonstrated by Katerina Kestemont.|
|09||Here the petals are ground deeper
||10||and the separation between high and low petals is accentuated.|
|11||I start grinding diagonally between the petal to create the over lapping of them.
||12||The shape of the petals is not defined yet.|
|13||With a narrow diamond wheel the separation between the petals is ground deeper.
||14||The flower gets some life. The texture of the coarse diamond wheel can easily be seen.|
|15||Also the back side is carved, taking into account the overall thikness of the flower.
||16||The next step requires small diamond coated tools with a finer grit.|
|17||At least 3 different shapes are used to schape the surface and the separation between the petals.
||18||The flower still looks bulky.|
|19||I proceed with a rounded and quite wide grinding tool.
||20||The surface and also the shape of the petals is defined.|
|21||Nicely seen here the shape of the petals.
||22||This is still a coarse grinding step and the tool leaves a rough surface.|
|23||Ondulating the petals carefully from the front and backside.
||24||And then working on the final thikness|
|25||of the petals.
||26||Working with a very thin diamond blade the separation between the petals is carved to its final depth.|
|27||I start grinding with silicium carbide wheels which are fashioned into exactly the same shapes as the diamond tools.
||28||Smoothing the surface first with roundes shapes, and then with narrower and sharper silicon carbide wheels.|
|29||At least 2 different smoothing grits are used (400 and 600 mesh)
||30||All carving traces have to disappear on the front and back side.|
|31||The shape has been ground to a thikness where it becomes translucent. Good material without cracks is required.
||32||The chrysopras flower is ready to undergo the fine grinding (1200 mesh) and final polishing step.|
|33||This is the reward for several hours of work.
||34||The finished chrysopras gemstone carving.|
