The Oct 2021 Preorder Period is now over. If you pre-ordered, laps will be shipping in February 2022, unless you chose Tucson pickup in which case you can pick up from uspersonally at the Tucson Gem Show Feb 1-6. Next Preorder will likely be in March and we will have a few extras to sell in person in Tucson as well.  See you then!


We are happy to present our favorite sintered laps for sale. We have been faceting with these for the past 4 years and they provide a great user experience. If you've been using plated laps, then upgrade your faceting game with sintered laps. These are a copper and diamond matrix on an aluminum.  The laps are light weight but with a long lasting lifespan.


Benefits of sintered laps
-Last longer (years instead of months)

-Cuts quickly and easily

-Smoother, more consistant surface texture on the facet versus plated



We are offering two sizing options (6" and 8") in three grits:

100 grit (160-325 Mesh) for Preforming

600 grit (28-40 Mesh) for Cutting

1200 grit (10-14 Mesh) for Fine Cutting


The laps have approximately 5mm (1/5") of diamond sintered copper. The blend is using a very high concentration of diamond.


The arbor size is 1/2".


Includes a dressing stick.



The prefoming lap cuts fast and smooth. Despite looking very agressive at 100 grit it gives a texture more like a 360 plated.


The 600 grit is the workhorse. If you are only planning to get one lap, this is the one. Often you can do all your cutting on this and jump straight to a prepolish.


The 1200 grit lap is for the stones that need an even smoother finish before going to prepolish. In some materials, such as synthetic corundum, you might experience orange peeling in certain directions.
