Understandably probably of yawn value to you but for believers it's another piece of evidence. There are at least 315 known gemstones. https://www.gemsociety.org/gemstone-encyclopedia/ Of them 19 ?? have a unique property detectable only when exposed to a CROSS POLARIZED light (laser) ** Exodus 28:17-21 Rev 21:19-21 List 12 gemstones These 12 all have the unique CROSS POLARIZED property ** How did man (thousands of years ago) without laser manage to LUCKY GUESS 12 of 19?? from a selection of 315 gemstones known today ? PS, not offended if you dismiss it as just a fluke equivalent to 2 consecutive 6/45 xlotto wins in a row
