 ### Main reasons for fork:
 * add more tools
 * make changes to code to make use of modern Minetest (such as ore drop string)
+* make 3D prerendered textures of gem (item) and mineral (and optional block textures)
 
 ### Notable issues found in original (see items marked with '!' in "Changes" section for others):
 (hopefully these changes get corrected there)

 ## Changes:
 '!' is for bugs in 2012 version that are fixed (as opposed to features that were changed/added) in this fork
+* (2017-03-20) Change garnet from Spessartine to pomegranate seed colored Rhodolite to reflect the original meaning of the word garnet (comes from the word pomegranate) -- see  and  https://www.americangemsociety.org/en/garnet-history
+* (2017-03-18) new textures for garnet: gem (item), mineral, block (realistic style)
+* (2017-03-18) tint of garnet block (classic style) changed to be that of Spessartine garnet
 * (2017-03-13) textures improved: opal mineral overlay, alexandrite classic block
 * (2017-03-13) default block style changed to classic
 * (2017-03-13) now uses settings from server's minetest.conf: birthstones_texture_style (can be realistic or classic)

 ## Known Issues
 * Improve remaining block textures
-* Make 8-bit style block textures (using default_diamond_block.png as luminance)
 * Make a trm for treasurer (separate mod)
 * Make variables based on real hardness values (but allow all birthstones to break the same types of blocks, for playability):
   * #of uses, dig times, and fleshy damage group value now all based on real-life hardness values (see xlsx spreadsheet for details and sources and extrapolation formulas)
