Adam and Eve:

5 Nestled in 6

So Elohim created Man in his own image,
 in the image of Elohim created he him;
 male and female he created them:

The five-point star is suggestive of the female form, even as the six-point star is suggestive of the male. In terms of geometry, then, the Crown Diamond agrees with scripture, in that its mathematics demonstrate both that the "woman" is taken/derived from the "man" and that the two (male and female) are One, both being portions of the Aysh/Man who became Adam/man and Eve/woman.

Note that the hexagonal sides forming the interior of the Crown Diamond's Mogan Dawid-- which enclose the Fields of Knowledge/Daat, the bosom of Avraham-- note also that they are precisely tangential to the circle enclosing the five-point star. The covering is complete. The illustration's stability speaks of the ultimate inevitability of reunion within every spiritual Adam, the marriage of the Bride and of the Lamb.
