If I recall correctly, Leopard and Lace woods come from the same tree, and are basically heart and sapwood or something like that. This piece might be from a region bordering the two, hence the slight "leopard" appearance in places.
If that's a piece from me, I might have another one Gerry. I haven't made any lace/leopard pens in a while, and I know I had several (5-10) blanks in total.
Do you know what the characteristics were of the wood that she liked? Was it the small circular "spots", or the other aspects of the grain/figure/color? Macadamia is another wood with a leopard-like appearance, but the color and figure are different. Here's a pic of one I made from Macadamia a while ago:<br />

You'll notice that the color is slightly different, and that the grain pattern is more pronounced than in most of the leopardwood I've seen. I have a few blanks of Macadamia, and I think Big Rob had some as well.
