Our Mission
Luxury diamonds,
grown not mined
Vajra Box connects the world's great diamond production centres — from Surat, the global capital of diamond cutting and polishing, to Antwerp's legendary trading expertise, London's celebrated Hatton Garden, the artistry of Paris, the scale of New York's Diamond District, and the Asia-Pacific reach of Melbourne. Founded in 2025, we bring together the very best of global diamond craftsmanship under a single, uncompromising vision.
We believe that a diamond should symbolise love, commitment, and beauty — not environmental harm or conflict. Every Vajra Box stone is grown in controlled laboratory conditions, certified by IGI or GIA, and crafted to the highest standards of the 4Cs.
Ethically Grown
Every diamond is conflict-free, sustainably produced, and fully traceable from lab to your hand.
Certified Quality
Every stone comes with an IGI or GIA certificate guaranteeing its cut, colour, clarity, and carat.
Bespoke Craftsmanship
Work with our master artisans to create a completely bespoke ring or jewellery piece, unique to you.
The 4Cs
Understanding Your Diamond
Every diamond is evaluated across four characteristics. Learn what makes a stone truly exceptional.
Cut
Ideal — Excellent
The cut determines a diamond's brilliance. We select only Ideal and Excellent cut stones for maximum light performance.
Colour
D — J Scale
From the rare colourless D to near-colourless J, we stock the full spectrum with expert guidance.
Clarity
FL — SI2
Inclusions and blemishes define clarity. We offer every grade with honest photography and professional guidance.
Carat
0.25ct — 5ct+
Carat is a measure of weight. Our collection spans from delicate accent stones to statement centrepieces.
