Lab Grown Diamond Engagement Rings from Kohira
An engagement ring marks the beginning of a lifetime together — a promise of forever. At Kohira, we believe this promise deserves a diamond that reflects not only your love but also your values.
Our lab grown diamond ring collection brings together timeless beauty and modern consciousness — designed for couples who want elegance with meaning.
Each ring is handcrafted with precision, using IGI-certified lab grown diamonds set in BIS-hallmarked 18K gold. The result? Exceptional brilliance, ethical origins, and unmatched craftsmanship that shines as bright as your love story.
What Are Lab Grown Diamond Engagement Rings?
Lab grown diamond engagement rings feature real diamonds — created in state-of-the-art laboratories using CVD (Chemical Vapour Deposition) or HPHT (High Pressure High Temperature) technology. These diamonds are chemically, optically, and physically identical to mined diamonds — offering the same sparkle, strength, and sophistication.
The only difference lies in their origin. Kohira’s diamonds are grown above the earth, ensuring every piece is conflict-free, traceable, and sustainable. Perfect for modern couples who believe in love that shines responsibly.
IGI Certification – Beauty You Can Trust
Every lab grown diamond engagement ring from Kohira comes with an IGI (International Gemological Institute) certificate, ensuring complete transparency and trust.
Each certificate details:
Cut: Ideal or Excellent for maximum brilliance
Color: D–F, the purest shades of white
Clarity: VVS1–VS2 for superior quality
Carat: From elegant 0.50 ct to statement 10 ct stones
Each diamond is laser-inscribed with its IGI number — your assurance of authenticity and certified craftsmanship.
