Lucky numbers agree with nothing
You can tell a real tradition from something bolted on later by counting how much the sources agree with each other. Nobody publishes that count. Here it is.
The measurement
For each field: how many distinct sign-and-value pairs exist across the twelve signs, against how many times any source states one. Where the two numbers are close, effectively every source is saying something different.
| field | distinct values | attestations | oldest source |
|---|---|---|---|
| element | 12 | 114 | antiquity |
| modality | 12 | 129 | antiquity |
| polarity | 12 | 78 | antiquity |
| lucky Number | 64 | 68 | modern only |
| lucky Colour | 50 | 89 | modern only |
| stone | 30 | 49 | modern only |
| flower | 17 | 22 | modern only |
| metal | 11 | 11 | modern only |
| tarotCard | 4 | 4 | modern only |
Twelve values, or 64
Element, modality and polarity manage exactly twelve values each — one per sign — across more than a hundred attestations spanning every century in the corpus. Every source that states them states the same thing.
Lucky numbers manage 64 distinct values across 68 attestations. That is very nearly one new answer per source, and not one source older than 1929 mentions them at all.
Neither of those is a reason to stop enjoying a birthstone. It is a reason not to be told it is ancient, and a reason the correspondence table on every sign page is banded by what kind of claim each row is rather than printing them all in one list at one weight.
