tags: #publish links: [[Gemstone Faceting equipment]] created: 2022-12-07 Wed --- # Darkside lap From Gearloose. Polymer composite **polishing lap** - oxide or diamond. Medium hardness stones, not hard stones (4-9 is claimed though). 200-400rpm. Use oxides sparingly to avoid scratching. Little water e.g. just spray. Low friction/heating due to good thermal conductivity. Hence need a little more pressure than [[Matrix lap]]. ## Instructions http://www.darksidelap.com/ [PDF brochure](https://www.aussiesapphire.com.au/assets/brochures/116_6.pdf) (from Gearloose via [Aussie Sapphire](https://www.aussiesapphire.com.au/darkside-polishing-lap-from-gearloose)) Forum discussion: http://gemologyonline.com/Forum/phpBB2/viewtopic.php?t=6917 ![[Darkside lap - label.jpg]]
