OUR STORY
Onya was born from a deeply personal moment — when two souls, eager to begin a life together, found that the wedding ring they loved was out of reach. That experience sparked a vision: to make beautiful, meaningful diamond jewelery accessible to everyone, for every milestone-jewelery that shouldn’t be locked away, it should be worn, cherished, and lived in.
Each Onya piece is crafted with the understanding that jewelry isn't just an accessory—it's an emotion, a memory, a promise.
With Onya’s lab-grown diamond pieces, celebrate your story, your way—embracing style, emotion, and sustainability. Our creations are designed for everyday elegance, so you can carry your milestones with you, always.

FREQUENTLY ASKED QUESTIONS
What are Lab grown diamonds ?
Lab grown diamonds (LGDs) are chemically, optically and physically identical to Natural Diamonds (NDs). The difference is just in their source. They are created in a lab reactor using a process that mimics how diamonds are made naturally below the Earth's mantle.
They have the same 4Cs as Natural diamonds:
- Cut
- Color
- Clarity
- Carat
Why are LGDs better than Natural Diamonds?
- Environment friendly, Ethical & Sustainable
- Higher brilliance due to lack of impurities
- 20% of the cost of natural diamonds.
Which jewellery certificate does Onya provide?
Our lab grown diamond jewelry is certified by leading global gemological institutes - GIA, IGI & SGL, the same authorities that certify natural diamonds. The gold is 14K/18K and BIS Hallmarked, ensuring authenticity, purity, and trust in every piece.

Are LGDs the same as moissanites or cubic zirconia or American Diamonds or Swarovski?
No, lab grown diamonds are real diamonds. Moissanites, Cubic zirconias or American stones or Swarovski are gemstones or glass. They are NOT DIAMONDS. They do not come with a certificate of authentication since they are not a diamond.
