This is American Holly, (ilex opaca). The wood has been become rare on the market due to the difficulty in getting white pieces. For decades almost the whole country relied on just one individual who had the special skill and equipment to acquire holly and dry it white. He has now retired. On its own, Holly dries to a grey color with green streaks. It must be dried rapidly and correctly in a vaccuum kiln to get white pieces. Note that holly, when it is polished is at best ivory white with some grain showing. Sometimes it looks whiter when rough cut. These are almost the whitest the wood can be. We currently cannot replace them.
