Red sandalwood and mahogany are common wood varieties, which are widely used in furniture, handicrafts and other fields. Although they have some similarities, they are also different in some important aspects. The following are the differences between them:

1. Species difference: rosewood refers to pteridaceae plants, while rosewood refers to many kinds of tree species, such as big-leaf mahogany, pointed-leaf mahogany and ebony.

2. Color difference: mahogany heartwood and sapwood are the same color, deep purple, mahogany heartwood is deep red and sapwood is light red.

3. Hardness difference: rosewood has higher hardness, harder than mahogany and better stability. Mahogany is soft and is mainly used to make furniture.

4. Value difference: Due to the slow growth and low yield of rosewood, coupled with its hardness and aesthetics, the value of rosewood is much higher than that of mahogany.

5. Maintenance difference: Because mahogany is stable in color, not easy to fade and has a long service life, mahogany is relatively easy to fade and deform, so it needs frequent maintenance.

To sum up, although there are some similarities between rosewood and mahogany, there are some obvious differences in variety, color, hardness, value and maintenance. Because of the scarcity and high value of rosewood, it is usually used in the fields of jade beads and high-grade furniture. Mahogany is suitable for ordinary furniture and handicrafts.
