Personal Advice in Nice

Compare diamonds and receive personalised guidance according to your preferences and budget.

 

Buying a diamond in Nice means being able to compare stones using reliable criteria and receiving advice tailored to your project. At i-diamants, we help you select certified diamonds based on their quality, grading report, visual appearance and your budget.

Choose Your Diamond

Every diamond has its own characteristics. Carat weight, colour, clarity, cut quality and fluorescence all play a role. We help you understand these key criteria so you can choose a stone suited to your project and budget.

GIA, HRD and IGI Certified Diamonds

Our diamonds are accompanied by grading reports issued by internationally recognised laboratories such as GIA, HRD and IGI. These independent reports describe the stone’s characteristics in detail and make it easier to compare diamonds using objective criteria.

Compare Several Diamonds

During your search, we can help you compare several diamonds with different characteristics and price points. The aim is to find the right balance between visual quality, grading report, proportions and budget.

 

Choosing a diamond is about more than comparing carat weight or price. Cut quality, clarity, colour, proportions, fluorescence and the grading report all influence the stone’s appearance and value. In Nice, i-diamants helps you understand and compare these criteria so you can make an informed choice suited to your project.

Understanding the Grading Report

A diamond grading report details the stone’s key characteristics, including carat weight, colour, clarity, cut quality, proportions and fluorescence. We help you understand this information so you can compare diamonds more effectively.

Comparing Diamonds

Two diamonds with the same carat weight can differ significantly in appearance and price. We help you compare their visual quality, proportions and characteristics to identify the options that best suit your requirements.

Choosing for Your Project

The right diamond also depends on the jewellery piece it is intended for. Whether you are looking for a loose diamond, an engagement ring, a wedding band or a bespoke creation, we advise you according to your project, preferences and budget.

 

Jeweller in Nice: Bespoke Jewellery Creation

At i-diamants, selecting the right diamond can be followed by the creation of a fully personalised jewel. Our bespoke jewellery approach allows the setting to be designed around the stone, your style and your project, whether for an engagement ring, wedding band, solitaire ring or a unique creation.

Bespoke Design

Each piece is designed according to your preferences, budget and selected diamond. We tailor the setting, metal and proportions to create a jewel that reflects your style.

From Diamond to Setting

The diamond and its setting are considered together to achieve a balanced, harmonious result suited to the way the jewel will be worn.

Guidance from Start to Finish

We guide you from the first ideas through to the finished piece, with expert advice at every stage of the creation process.

 

Behind every polished diamond lies a precise and highly skilled process requiring experience, technical knowledge and careful judgement. The diamond dealer analyses the rough stone, assesses its potential and determines the cutting stages that will best reveal its brilliance, proportions and value.

At i-diamants, this diamond expertise is at the heart of our approach. It allows us to better understand each stone’s characteristics and provide more precise guidance when helping you make your selection.

Marking

 

The diamond cutter carefully studies the diamond from all angles and draws a cutting line in India ink to give instructions for sawing and/or cleaving.

Cleavage

 

This technique, known for more than 2000 years, is used to split a diamond in two. After cutting a notch in the diamond, a steel blade is placed in this slot. The principle is to give a sharp blow with a mallet on the blade which is fixed at a very precise angle. The cleavage is done parallel to the crystallite grain. Diamond is a bit like wood, there is a direction in which it is easy to split (parallel to the wood grain) and in the other direction (perpendicular to the wood grain) where it is much more difficult to split.

Sawing

 

Sawing allows a diamond to be split in a non-cleavable crystallization plane. With the traditional method, the diamond is placed on a vertical blade rotating at high speed, which saws it very slowly. Nowadays, diamonds can be sawn very precisely by a laser beam. The sawing is done against the crystallite grain.

Scraping

 

Known since the Renaissance, rough cutting is the process by which the future rondiste (or girdle, the round part of the diamond) is created, by cutting the stone against another diamond. This phase consists of rounding the diamond's belt before it is cut into facets. This is the preliminary operation to the cut. It prepares a rough outline of the shape the diamond will have once cut.

Faceting

 

On a polishing wheel, each facet is cut on the stone, one by one. Generally, a brilliant is cut by different people: a cross cutter (who cuts the table, the 4 main facets of the crown and the breech), eventually by the 8/8 cutter and then finally by the brillanteur. When all the facets are cut, the diamond is ready to be set in a jewel.

 

These professions belong to the same world, but they involve different areas of expertise. A diamond dealer specialises in diamonds, their evaluation, cutting and selection. A jeweller designs and creates jewellery set with precious stones, while a jewellery maker works more broadly with jewellery and precious metals.

At i-diamants, these skills come together to guide you from the selection of the diamond through to the creation of the finished piece, with particular attention to the stone, the setting and your project.
