Leather Polishing Pads, Oxide and Diamond Polishes When I talk to people about their favorite polishing techniques, I find that works for them may not work for me and vice versa. Here are the old standbys that seem to work for everyone. Leather Polishing Pads Leather pads are used for polishing with oxide polishes such as cerium oxide or tin oxide. We have two types of leather pads: cowhide and elk. Cowhide has a rougher surface than elk. Leather pads do NOT have an adhesive backing. So, you have to use feathering cement to attach them to a base plate or master lap. Feathering cement can be found on our accessories page.
Tin Oxide Tin oxide is a great polish for most cabbing materials, glass and any material containing quartz. It is the polish of choice for marble. Many other stones in the hardness range of quartz and softer polish best with Tin Oxide. Often, when a full polish can't be obtained on a stone, tin oxide will do the trick. Our Tin Oxide is 99.9% pure.
Aluminum Oxide (Alumina)
Aluminum Oxide "A" is used for polishing tourmaline, beryl, garnet, topaz, peridot, danburite, etc. Sometimes topaz, peridot and danburite don't polish well with Aluminum Oxide and polishing with diamond is required. Aluminum oxides labeled as "A" are not all equal in quality or performance. Check the size of the grit. In order to be of top "Linde" quality, Aluminum Oxide "A" should be .3 micron in size, and Aluminum "B" should have an extremely small micron size of .05. To put this into perspective, 50,000 grit is .5 micron and 100,000 grit is .25 micron. For more information on grit vs. micron sizes, check out our How-To & Tips Section. Aluminum "B" polishes very slowly and is mostly used on soft and difficult stones. We no longer sell it.
LapidaryPro
High Grade Friable Diamond Powder LapidaryPro diamond is the highest quality synthetic diamond available. Unlike other diamond that rounds out when worn, LapidaryPro diamond is friable and retains sharp edges that continue to cut, even as the diamond particles wear down. So, less diamond is needed and it lasts longer. LapidaryPro diamond is also very finely graded, which means the powder is extremely uniform in size. So, it cuts like one would expect it to, and with less of that problematic scratching that is so well known to those of us who use loose diamond for grinding and polishing. We stock LapidaryPro High Grade diamond powder from 325 to 200,000 grit in 5 carat, 25 carat and 50 vials.
Italdo Diamond Spray
Italdo Diamond Spray was the first diamond spray on the market and it is still the best. Italdo contains the finest friable diamond, which continues to expose a sharp edge to facilitate quick polishing, but without scratching. Italdo uses the flotation method to grade their diamond grit. The floatation method sorts out different grit sizes with incredible accuracy. The result is quick pre-polishing and polishing, with no hazing or scratching caused by oversized diamonds. Italdo uses a special water/oil carrier that is ideal for ceramic laps. We highly recommend Italdo Diamond Spray on all types of pre-polishing and polishing laps. The spraying action is done by a pump, so it contains no harmful CFCs.
This item can not be shipped outside the US.
