How do I describe beauty?

A certain lady of elegance
Who wanted concrete evidence
That when I say she is beautiful
It is the truth without pretence
Asked me to describe her beauty with eloquence
.....
However I have hit speech impediments
How do I describe her radiance?
How do I start describing beauty?
How do I articulate it truly?
This is a painstakingly difficult duty
.....

Do I tell her that she is the
priceless image of Isis?
That she is the apotheosis
of the elegance of Pisces?
The task indeed has me freezed
caught in a crisis
.....
How about I speak of her
strong cheek bone,
or her own unique natural
African skin tone?
Her scintillating smile
Her hidden-lid eyes
Her natural braided hair
that is a gift from the skies?
.....
Her eyes forever sparkle
I gaze at them and marvel
Her iris glittering a permanent tear
Her lens is a blistering armament flare
Eye-lashes
like the sun's rays flashing
piercing through the clouds on a rainy day
Would it be fine
for me to describe her beauty this way?
.....
Perhaps I should touch
upon her physique
Body created to near perfection
with technique
Simultaneously slim and thick
She is a natural mystique
She gets that from her martenal lineage
Just a glimpse of her is a privilage
She was designed with precision like the pyramids
.....
I do not mean to sound unruly
It is impossible to describe such beauty
