From the source to the finished piece, Maison Celinni ensures complete traceability, from the extraction of the diamond through to the final delivery of your jewelry, in keeping with our founding values: responsibility and transparency. We are committed to offering some of the fairest prices on the market, true to the very essence of our Maison — making luxury more accessible. Your satisfaction remains at the heart of everything our Celinni diamond experts do.

Why Do We Sell Our Diamonds for Less?

Diamonds Direct from Antwerp, with No Middlemen

As a diamond dealer and member of the Antwerp Rough Diamond Bourse (Antwerpsche Diamantkring), Maison Celinni provides its clients with diamonds at direct prices, without intermediary markups.

This direct purchasing model allows us to offer prices up to 60% lower than traditional jewelry stores for comparable quality. We also offer exceptionally rare grades, including diamonds above G color and VS1 clarity. Maison Celinni specializes in particular in D–FL and IF diamonds, among the most sought-after quality grades on the market.

Direct Access to the World's Leading Diamond Trading Centers

Celinni.com features more than 150,000 diamonds, with stones physically available across the world's major international diamond exchanges, including Paris, Mumbai, Antwerp, Hong Kong, New York and Tel Aviv, among many others.

Our advanced information system allows us to monitor the availability of each stone around the world in real time. This exceptional selection enables Maison Celinni to provide one of the largest and most competitively priced diamond offerings on the market.

A Dual Certification Guarantee

All our diamonds come with one of the following two guarantees:

Certification issued by internationally recognized independent laboratories — GIA, HRD and IGI, three of the world's leading authorities in gemological grading and expertise.
Certification issued by Maison Celinni, which is authorized to provide appraisal reports recognized by insurance companies.

This enables us to offer you an exceptional selection of diamonds at some of the most competitive prices on the market.

Understanding the Life Cycle of a Diamond

To understand why buying diamonds directly can make such a significant difference to the final price, it is helpful to look at the journey a diamond typically takes before reaching a traditional jewelry store. In the conventional supply chain, a rough diamond generally passes through several intermediaries: a rough diamond trader, a cutting and polishing workshop, a wholesaler, sometimes a second regional specialist wholesaler, and finally the retailer who sells the diamond to you.

Each intermediary adds its own markup, which can significantly increase the final retail price compared with the diamond's original price at the source.

As a direct member of the Antwerp Rough Diamond Bourse, Maison Celinni eliminates several of these intermediary stages. Our diamond experts purchase stones directly, without relying on a long chain of successive traders. It is this elimination of multiple intermediary markups — not a reduction in diamond quality — that explains most of the price difference between Celinni and traditional jewelry stores.

Other Reasons Behind Our Competitive Prices

Beyond purchasing diamonds directly through the diamond bourse, several structural choices explain why we are able to maintain consistently competitive prices:

Controlled overhead costs: despite the prestige of our locations, our rents remain significantly lower than those of traditional jewelry stores situated in the heart of major shopping districts. Without costly retail premises or oversized inventory, we pass these savings directly on to our customers through more competitive prices.
Full control over the creation process: from selecting the diamond to crafting the finished piece, every stage is handled through our workshops in keeping with the finest traditions of Parisian jewelry craftsmanship. Delivery is complimentary, whether to your home or to one of our jewelry stores.
Lower advertising costs: unlike many jewelry brands that invest considerable amounts in marketing and advertising, we deliberately keep these expenses under control so that we can offer our customers a more competitive final price.
Significant sales volume: with more than 15 years of experience in the online diamond industry, Maison Celinni benefits from substantial sales volumes, allowing us to operate with lower margins while passing the savings on to our customers.

How Can You Verify the Quality and Authenticity of Your Diamond?

Buying a diamond online, even at an attractive price, should never be done without proper verification. At Celinni, every diamond we offer can be assessed according to several objective criteria, regardless of its listed price:

Certification: always check that the grading report — whether issued by GIA, HRD, IGI or Celinni — corresponds to the diamond being offered. You can do this by comparing the certificate number laser-inscribed on the diamond's girdle with the number shown on the grading report.
The 4Cs: color, clarity, cut and carat weight should always be clearly stated and consistent with the price of the diamond. A transparent diamond expert will explain each of these criteria in detail before you make your purchase.
Traceability: Maison Celinni is committed to complete traceability, from the extraction of the rough diamond through to the delivery of the finished piece of jewelry, in accordance with the Kimberley Process, which helps ensure the responsible sourcing of diamonds.
Personal guidance: beyond certificates and documentation, an appointment with a diamond expert, either in one of our showrooms or at your home, gives you the opportunity to ask questions and examine the stone in person before making your decision.

Why Entrust Celinni with the Creation of Your Jewelry?

Bespoke Jewelry, Crafted Piece by Piece

We deliberately keep limited inventory because every piece of jewelry is unique. Each order is therefore made to order and handcrafted, ensuring a high level of quality while keeping prices under control.

In-House 3D Jewelry Design

The 3D modeling of your jewelry is carried out in-house, allowing us to remain flexible and responsive throughout your bespoke jewelry design project.

We provide the initial design of your jewelry free of charge, along with a wax model before production when necessary, so you can approve the design with complete confidence before the final piece is created.

Recognized Expertise in 950 Platinum

Maison Celinni specializes in crafting jewelry from 950 platinum, a precious metal that requires specialized expertise and craftsmanship that few workshops today master with the same level of precision.

Denser and more challenging to work with than gold, platinum requires specific tools and technical expertise that our artisans have developed over many years, enabling us to create pieces ranging from timeless classics to decidedly contemporary designs.

Does Buying Online Change the Diamond Jewelry Shopping Experience?

Many prospective buyers are still hesitant about buying a diamond online, fearing they may lose the personal guidance traditionally associated with purchasing jewelry in a physical store. At Celinni, this should not be a barrier: online diamond shopping does not replace personalized advice — it complements it.

Every purchase can be preceded by a consultation with a diamond expert, whether by phone, video call, during an appointment at one of our jewelry stores, or in the comfort of your home. This means you retain all the benefits of traditional, personalized service — expert guidance, answers to your questions, and the opportunity to see and handle the diamond before purchasing — while benefiting from the lower operating costs associated with our direct-sales model.

It is this combination of human expertise and an optimized business model that enables Maison Celinni to offer significantly more competitive diamond prices without ever compromising on personalized service.
