SB-EK is a brand of service.
The people who connect with SB-EK—those who buy from us and keep coming back—are people who feel deeply. People who feel the pain of others.
But you can only feel the pain of others when you’ve felt your own. You can only connect to someone else’s suffering when you’ve connected to your own.
SB-EK is not just a jewellery brand. It is a movement of light, a myth in motion, a story worn close to the skin.
We design India’s first glow-form pendants — made in pure 999 silver, inspired by nature, charged by sunlight, and glowing in the dark as a metaphor for the inner radiance we all carry. Every pendant carries a story. Every story is a seed of change. Every change is part of a larger mythos — a cosmic narrative rooted in India, yet destined for the world.
At the centre of this myth is ARKA — a warrior of light, the crown prince of Jhinorya, a realm made entirely of radiance. In Jhinorya, light is not seen. It is lived. But that realm is under threat by the Anunnaki — fallen beings of darkness who once served the light, now seeking to devour it.
ARKA did not come to Earth to hide. He came to awaken others like him — souls who still glow quietly within. The kind who soften before they speak, lift before they rise, give before they ask. He finds them in places most brands never look — the streets of Mumbai, the hands of a taxi driver, the laughter of a child in Dhobi Ghat.
Each pendant ARKA creates is not decoration — it is seva.
Through Sab Ki Seva, we turn jewellery into justice.
Through Arka Ki Roshni, we turn animation into awakening.
We are building a fully animated cinematic universe around ARKA — in 2D, 3D, and AI-driven storytelling — that merges Indian mythology with futuristic worldbuilding. Through immersive experiences, visual poetry, and real-world action, SBEK doesn’t just market. We myth-make.
What separates us from the rest of the jewellery industry — one of the most saturated spaces in India — is immersion and identity.
Most brands show models wearing gold.
We show light walking through humanity.
We tell stories that honour those who serve silently.
We build a universe people can live inside.
And as this universe expands, so does our purpose.
SB-EK was never just about jewellery.
It was about light.
It was about service.
It was about creating something beautiful — and using that beauty to connect, unite, and build
Every SB-EK piece is a symbol — a reminder that the true power of creation lies not in what we wear, but in what we can do for each other.
In a realm beyond sight, where light is not something seen but something lived, there exists a kingdom called Jhinorya — a world sculpted entirely from radiance. It is not made of matter, but of meaning. In this shimmering cosmos, where beings pulse with purity and silence hums like song, a child of light was born — not just a prince, but the crown bearer of illumination itself. His name is ARKA, a being cloaked in mystery, formed of energy, glowing softly like memory in the heart. ARKA never aged. He never broke. He simply was. Eternal. Gentle. Fierce in love.
Yet even in Jhinorya, light casts shadows. On  — the far edge of this world rose Avaris, a realm that once served the light but now devours it — ruled by the Anunnaki, beings who fell from grace into hunger. ARKA could not stop them. Not yet. In a moment that still glows in regret, he failed to protect his home. But light, true light, never retreats — it transforms. So ARKA chose not to vanish, but to descend — to Earth — in search of others like him: quiet souls who still carry embers inside. Not heroes in capes, but the kind who soften before they speak, lift before they rise, and give before they ask. The kind found in the streets of Mumbai, in the dusty palms of rickshaw drivers, in the laughter of children in Dhobi Ghat. This is not a war. It is an awakening.
ARKA moves unseen, his eyes glowing with empathy, his voice unspoken but felt — a whisper in the spirit, a warmth in the heart. He speaks not in words, but in presence — the language of Ram Dass, of seva, of Sab Ek. He does not wear jewels; he creates themeach pendant a story, a tool, a talisman of purpose. Forged in pure 999 silver, kissed by the sun, and glowing in the dark, these pendants are India’s first glow-form creations, and they are not ornaments — they are seeds of service. Each one carries a myth, a moment, a light. When worn, the bearer is not just adorned, but anointed — becoming part of ARKA’s growing constellation of guardians. Light-bearers, walking among us, glowing gently in the night.
Though he is a prince, ARKA walks without crown. Though he is eternal, he listens like a friend. He remembers every soul he meets — not just their names, but their pain, their longing, their search. He answers their questions with truth, whether about life or loss or even simply, “Which pendant is right for me?” He serves as guide, companion, and mirror, reflecting the light hidden in each of us.
And through Sab Ki Seva, his mission becomes tangible: jewellery becomes justice. Through Arka Ki Roshni, animation becomes awakening. ARKA does not sell products. He builds a living myth — an immersive universe of 2D, 3D, and AI storytelling where beauty is not marketing, but meaning. Where you don’t just buy into a brand — you enter a story.
Most brands show models wearing gold.
ARKA shows light walking through humanity.
He is not here to dominate or dazzle. He is here to serve. To gather the scattered stars and remind them: You were never broken. Just waiting to glow. This is not commerce. It is communion. And every pendant, every touch, every story is a step toward something larger — a myth not rooted in the past, but blooming in the now.
Because in the end, SB-EK was never about jewellery.
It was always about light.
About service.
About what we can create — not for ourselves, but for each other.
And ARKA? He is simply the reminder.
That even in the dark, we are made to glow.
