50+ Years With Diamonds
The RJ House Journey
Our family has worked with diamonds for more than 50 years, beginning in natural diamond manufacturing. That experience grew into growing and cutting our own lab-grown diamonds, and from there into making the jewellery they are set in.
Rangani Jewelry House brings that knowledge together: lab-grown diamonds set in 10K, 14K and 18K gold and 925 sterling silver, made with the attention to detail that comes from understanding a diamond from the inside.

Principles
Our Mission and Values
Rangani Jewelry House exists to prove that extraordinary diamonds should not cost the earth — in every sense of the phrase. Master craftsmanship, honest sourcing, and diamonds grown rather than mined, so beauty never comes at the expense of conscience.
Integrity
Honesty in how every material is sourced and every piece is priced — standards we would be proud to explain in full.
Craft
Respect for the skill of the artisans who shape each setting, continuing techniques taught bench-side.
Permanence
Jewelry designed to be passed down rather than replaced — made for decades of wear, not a single season.
Etymology
The Meaning Behind the Name
“Fine jewelry should feel personal and alive — not simply valuable.”
Rangani draws from a word rooted in color and richness, a nod to the vivid life a well-made piece of jewelry brings to the person who wears it.
Paired with House, the name signals belonging rather than transaction — a family atelier and, by extension, a home for every client who enters it. The name has stayed a constant through every evolution of the craft.
Distinction
What Makes Us Different
Rangani Jewelry House builds exclusively with lab-grown diamonds and responsibly sourced gold — a deliberate choice rather than a trend, so clients never have to weigh brilliance against conscience.
