Cabbing Rough and Slabs

Many of the names are varietal and do not indicate the actual mineralogical composition of the material.

Looking for Finished Cabs? - Please see our cabochons section

If there's anything you're looking for, please contact us. We have some slabs of interesting Franklin / Ogdensburg (NJ) material not shown on here.

Lapidary slabs are typically photographed wet, because the rough surface does not show the color well. The wet appearance simulates what it will look like with a good polish.



Assorted pieces - Lapidary bulk assortment including Quartz ("rock crystal"), Agate, Unakite, Obsidian, Jasper, Crazy Lace (?), and a couple of small pieces of Rhodochrosite. Almost 17 lbs of cabbing / slabbing / tumbling rough in all!

Some of the pieces (e.g., the crazy lace) are a bit oddly-shaped and would be expected to yield smaller cabs. You should be able to get at least one usable cutting out of each piece in this lot, with some pieces yielding considerably more.

Recommended shipping method: USPS Flat Rate box ($10.75, USA only). Nothing else will fit in the box. If you want to order anything else in the same order, please contact us and we can send you a Paypal invoice with all shipping calculated.

Pieces were photographed WET. Each picture shows different pieces. Lot includes contents of both photos (except for tray).
