Leopardwood is generally much more dense and heavier than lacewood. I have leopardwood in my shop that has small fleck in the grain, honestly about the size of a pin head. I have another piece of leopardwood that has long stripes of fleck that are 1/4" wide by about 2 1/2" long. You really can't go by the size of the fleck in the grain. The lacewood I bought years ago did have more of a pink tint to the fleck in the grain, where leopardwood has more of a tan color in the fleck. Leopardwood also generally has somewhat of a waxy feel to it. Lacewood when turned will be almost a powder rather than a fine chip like leopardwood. Hope this helps a bit.
