Rizalites & Bikolites!!!

We have a nice selection of the finest Philippinites that we have ever seen on the market. The Bikolite-types were acquired over a 7-year period from placer gold miners on Luzon. We bought all we could get, and there's no assurance that we'll be able to get any more when these are gone, so don't procrastinate. The Rizalites are from two other old collections, including a selection of monsters from the collection of the late H. Otley Beyer, the father of Philippine tektites. Beyer first recognized and described these in 1926 and proceeded to assemble the finest Philippinite collection in history.


There are two basic types: classic spheres with amazing breadcrust ornamentation, and phenomenally grooved curved polygonal flakes. Although I have never seen this written up, it is clear that the two types are related in the following fashion:

The deeply ornamented polygonal flakes typically have rounded concave basal surfaces (as in image #2). These surfaces nicely match their counterparts on the breadcrust sphereoids in both curvature and polygonal form. This relationship indicates that the crust of the primary bodies initially developed deep, complex grooving and a relatively systematic pattern of breadcrust cracks. In the advanced stages of this process, concentric shells split away from the cores, possible due to thermal expansion of the outer surface during their final plunge through the atmosphere. Note that image #4 above is an actual specimen with part of the textured crust still attached. It forms a perfect series with image #3, but different specimens are involved.

It is also interesting that the relative abundance of the two types matches what the above model would predict: every ball has around a dozen polygonal uplands, which we would suppose would yield an equivalent number of polygonal flakes; that is to say that the ratio of balls to flakes should be around 1 to 12. In our inventory, the ratio is about 1 to 15----close enough!


Following is our present inventory. Please email us for detailed images of specific specimens if desired. Variations in price per gram reflect our perception of relative quality. This is amazing stuff!

Most of these have a relatively smooth, concave lower surface and a convex, deeply ornamented upper surface. See introductory text and illustrations.
