Our Materials

Crafted, Not Mined — Because Shine Shouldn’t Cost the Earth.

At Grandma Jojo’s Lab, every jewel begins in a lab — not deep underground.
We don’t dig, we design. Our gemstones are born from science and finished by artistry, created to catch the light with fearless brilliance.

Our Gemstones

We use high-quality cubic zirconia (CZ) — lab-crafted crystals known for their diamond-like radiance and rainbow fire.
Each stone is precision-cut to dance with light, rivaling natural gems without the environmental weight of mining.
They’re not “imitations.” They’re innovations — responsibly made, endlessly bright.

Why We Love Them

  • Dazzling brilliance that rivals natural gems

  • Ethically made — no mining, no guilt

  • Durable for everyday wear

  • Accessible, so everyone can shine their way

Our Metals

Every piece from Grandma Jojo’s Lab is crafted with fine metal alloy, plated in 18K gold (Au750) or sterling silver (S925).
The finishes come in golden or silver tones — both chosen to keep their glow and resist fading through time.
Each piece bears its purity mark, a quiet promise of authenticity and care.

Why We Choose These Materials

Because we believe jewelry should celebrate joy, not privilege.
Our materials let us design boldly — jewels that look royal, feel personal, and invite you to wear them everywhere: at work, at karaoke, or on your way to somewhere new.

Sustainably made. Beautifully accessible. Fearlessly bright.
That’s the promise behind every creation from Grandma Jojo’s Lab.
