P550_61 – APOLLO BOTTOM PRESSPOTS
Apollo bottom pots where initially made for automatic machines but since the introduction of the rough and polished analizers, the crown height is being indicated by percentage depth and apollo pots became more common in the manual polishing. Also the wider variety of diameters gives a more precise fit for the diamond and hence increases the quality of the polished. Available depths : 13% – 14% – 15% – 16% – 17% – 18% – 19% – 21% – 23% . Other depths can be made on request with a minimum of 100 pieces per size and depth. Example : Size Nr 36 stands for stone diameter of 3,60 mm .
