Our Standard.
Not a Selling Point.
Every piece we make is built on a foundation of independent certification and traceable origin. This is not marketing language. It is the baseline below which we do not go.
It is the condition under which we operate."
In an industry where terminology is often stretched and provenance is rarely questioned, we chose a different path from the beginning. Every natural diamond we set carries independent third-party certification. Every gram of gold is BIS Hallmarked. Every stone is conflict-free and traceable. This is not exceptional. This is what jewellery should always have been.
The Certification Behind Every Piece
Gemological Institute of America
Applied to all diamonds 0.25ct and aboveThe GIA is the world's foremost authority on diamonds. Established in 1931, it created the universal 4Cs grading system — Cut, Colour, Clarity, and Carat — that the entire industry relies on. A GIA certificate is not a sales document. It is an independent scientific assessment of exactly what you are buying.
Every MK DIAM centre stone of 0.25 carats and above is GIA certified. When you receive your piece, you receive the certificate with it — a permanent, verifiable record of your diamond's identity.
International Gemological Institute
Applied to melee diamonds and smaller stonesThe IGI is one of the largest independent gemological laboratories in the world, with a particular strength in grading melee diamonds — the smaller accent stones that surround a centre stone and define the brilliance of a full piece.
Every melee diamond in an MK DIAM piece is IGI certified. The brilliance you see in the full setting is not incidental. It is graded, documented, and accountable.
Bureau of Indian Standards
All gold — 14K and 18K — is BIS HallmarkedBIS Hallmarking is India's official gold purity certification, administered by the Bureau of Indian Standards under the Government of India. A BIS Hallmark guarantees that the gold in your piece is exactly the karat stated — no more, no less.
All MK DIAM pieces are crafted in BIS Hallmarked 14K or 18K gold. The hallmark is stamped on every piece. Your gold is not an estimate. It is a guarantee backed by the Government of India.
Ethically Sourced · Traceable Origin
All diamonds confirm adherence to WDC SoW and WFDB/OECD guidelinesEvery diamond we use is conflict-free. We source exclusively from suppliers who confirm adherence to the World Diamond Council's System of Warranties (WDC SoW) and operate in alignment with the WFDB/OECD guidelines for responsible supply chains.
Surat's position as the world's diamond cutting capital gives us direct access to the supply chain at its source. We use that access with intention — sourcing only from suppliers whose documentation and ethical standing we have personally verified.
The Case for Natural Diamonds
A natural diamond formed between one and three billion years ago, under conditions of extreme heat and pressure deep within the earth. That process cannot be replicated. It can only be found.
Natural diamonds have held value across centuries and cultures. They are among the few objects that retain meaning — and worth — across generations. A piece made to last deserves a stone made to last.
Every natural diamond is unique. No two stones are identical in cut, colour, clarity, or formation. The diamond in your piece exists nowhere else on earth. That is not sentiment. That is geology.
MK DIAM works exclusively with natural diamonds. We do not offer lab-grown alternatives. This is a considered position — one rooted in our heritage, our values, and our belief in what fine jewellery represents.
Every diamond is graded for superior cut, quality and assessed independently — by GIA, IGI, or both. Our role is to select, set, and stand behind what the certificate confirms. Nothing more, nothing less.
Maximum benefit to the consumer — always. Every decision we make on certification, sourcing, and pricing is made with the buyer's interest as the first consideration. Transparency is not a policy. It is our position.
