Diamond Manufacturing
What does Anand Exports do? Anand Exports is a vertically integrated B2B diamond manufacturer based in Surat, India. We handle the entire supply chain internally, from mine-direct rough diamond procurement to high-precision lapidary polishing and GIA certification, ensuring conflict-free origin and wholesale pricing.
Unlike brokers, Anand Exports controls every stage of the diamond pipeline — from mine-direct rough procurement to the final certificate that ships with your order. This integration allows us to guarantee quality, provenance, and pricing accuracy at every step.
Our facility in the Bharat Diamond Bourse houses 60+ master lapidaries and an on-site grading room, while our laser planning workstations are based in Surat — all operating to GIA Triple Excellent production standards.
Six carefully managed stages transforming rough earth into certified, brilliant-cut diamonds ready for the international market.
We source parcels directly from licensed primary mines in Botswana, Russia, and Canada — avoiding secondary markets that obscure provenance. Each parcel arrives with a Kimberley Process Conflict-Free Certificate and full chain-of-custody documentation.
Every stone passes through our on-site grading room. Our senior gemologists sort by colour (D–Z), clarity (FL–I3), and rough crystal quality. Stones that do not meet our internal thresholds — which exceed GIA minimums — are returned or auctioned off the primary line.
Selected rough stones are scanned using Sarin and OGI Systems technology, generating exact 3D crystal models. Our planning software calculates the optimal cut that maximises retained carat weight while achieving the highest possible light performance grade. Each plan is reviewed by a senior lapidary before approval.
Following plan approval, stones are cleaved or laser-sawn along crystallographic planes. The girdle is then formed by computer-controlled bruting machines, creating the circular profile required for brilliant cuts — or the precise outlines for step and mixed cuts.
Our master polishers work each stone across spinning iron scaife wheels charged with diamond dust, placing every facet to within .01 symmetry tolerances. Table, crown, pavilion, and girdle facets are polished individually, with inter-stage quality checks at each station.
Finished stones are submitted to GIA, IGI, or HRD for independent grading. Once certified, each diamond is packaged in tamper-evident security pouches, insured for full replacement value, and shipped via our bonded carrier network with real-time tracking. Complete customs documentation is provided for every destination country.
Every step of our process is governed by a single principle: that doing the right thing and producing the finest diamonds are not competing goals. From Kimberley Process compliance at the mine gate to acid-free packaging at despatch, we hold ourselves to standards that exceed what any certification requires — because our buyers' trust depends on it.
Wholesale rough parcels from 0.03ct to 5.00ct per stone. Available in mixed colour/clarity lots or sorted by specification. Minimum parcel: 10 carats total weight.
GIA or IGI-certified polished round brilliants and fancy shapes in all standard sizes. Triple Excellent cut grade available across our premium line. Melee and calibrated sizes also available.
Bespoke lapidary services for clients who supply their own rough or wish to commission specific cut specifications — including proprietary branded cuts for jewellery maisons.
A GIA cut grade is a necessary baseline — not the ceiling. Anand Exports uses Sarine's Light Performance analysis on select stones, producing independent scores for Brilliance, Sparkle, Fire, and Light Symmetry.
Sarine reports are becoming a buying requirement for Japanese and European high-jewellery manufacturers who demand measurable optical quality beyond GIA proportions alone.
Return of white light — the primary brightness indicator face-up.
Scintillation — the play of light and dark as the stone moves.
Spectral colour dispersion — the rainbow flashes inside the stone.
Optical symmetry of the light pattern — Hearts & Arrows standard.
Every polished diamond is supplied with independent certification from GIA, IGI, or HRD Antwerp on request. All rough and polished parcels ship with Kimberley Process certificates confirming conflict-free provenance, along with full customs documentation.
We supply both single certified stones for bespoke commissions and bulk calibrated parcels for manufacturers. Minimum order is flexible and discussed per inquiry — we work with independent jewellers and large luxury houses alike.
Yes. We export insured, fully documented shipments to our six core markets and beyond, including the United States, Belgium, Israel, the UAE, Hong Kong, and Brazil. All shipments include certification and Kimberley Process paperwork.
Laser planning uses 3D scanning and optical modelling to map the interior of a rough crystal before cutting. This maximises carat yield and light performance, ensuring each finished diamond achieves the best possible cut grade from the available rough.
Standard polished orders ship from existing stock quickly. Bespoke lapidary commissions, including proprietary branded cuts, have a typical turnaround of 6 to 12 weeks depending on shape, size, and quantity.
