Possibly obsidian for the bottom grain? Hard to tell - but a very beautiful garnet and love how the shadows work well with that bottom grain and the light reflecting from the right. Beautiful reflection and printed as a stunning 11"x14" print mounted in a 16"x20" double mat. The mat will have a small window under the print where the actual sand grains are separately adhered to the mat! Each 1of1 print will be printed ONE time ever!
