Our Story

We are sister friends

Hi! We’re Crystal Khalil and Dr. Nicole LaBeach.  We call ourselves the Wonder Twins! Together, Zan and Jayna were sibling super friend superheroes from the Justice League in the 1970s.

When they activated their powers, they did extraordinary supernatural things.   Its worth a laugh every time we say it, but the sentiment is trueWe are sister friends with superpowers that once combined shine forth undeniable brilliance

To our tribe, we’re executives, business women, great huggers, and ambassadors of service It’s no surprise, our faith and fierce commitment to empowering the human spirit brought us together. Similar paths, life lessons, and calls to action, we were two diamonds cultivated by fire and pressure.   

In 2020, during one of the most tumultuous times our world has ever seen, we decided our collectivism could not only change lives but be our greatest decision and contribution yet. Together, we would create a brand that empowered others through love,  light and experiences likened to sav for the soul – We created Sister Diamonds, LLC. Its been proven, only a diamond can cut another diamond, and that’s what we do.

We create space for women to celebrate, support, elevate, cultivate, and honor themselves and othersWhen we look in the eyes of a sister woman, we see futures so bright it makes us want to wear shades. And, we figured out our greatest joy is being in service to honoring the purpose, presencepower, and leadership of sister women from all walks of life.

As Sister Diamonds we’ve embarked on a  journey of a lifetime and all other Sister Diamonds are welcomed to join us!
