Abstract (en)

[origin: WO2018016966A1] Gemstone cutting and polishing apparatus comprising two main components: a precision divider (100) and an angle and elevation platform (200). The precision divider (100) is arranged to cut and polish a desired number of facets in a gemstone with high precision. The precision (100) divider is attached, preferably releasable, pivotal to the angle and elevation platform (200). The precision divider (100)can be positioned and locked in an angle between 0° and 90° withrespect to the horizontal level, to produce precisely cut facets in the gemstone with desired angles. The precision divider (100) is provided with an improved dopstick receptacle (106) with a non-circular cross-section, and a correspondingly shaped dopstick (500, 503), thus providing a highly fixed and stable attachment of the gemstone being processed.
