— The 4Cs —

The quality of a diamond depends on four key factors

The quality of a diamond is measured by four fundamental characteristics known as the 4Cs: Cut, Colour, Clarity and Carat.

At Diamantes.com, we break down these elements so you can make informed decisions, whether you’re looking for a unique piece of jewellery or want to invest in diamonds.


The cut of a diamond refers to its shape, proportions and cut quality.


The colour of a diamond is one of the most important factors influencing its value.


It is a critical measure that assesses the presence of internal inclusions and imperfections.


Carat weight is a measure of the mass of a diamond.

At Diamantes.com we emphasise that the diamond market is dynamic, and prices can fluctuate due to global economic factors, demand in specific markets and the rarity of certain characteristics. In addition, provenance and sustainability may play an increasingly important role in the valuation of diamonds, with a growing number of consumers looking for ethically sourced options.

To obtain an accurate and up-to-date estimate of the price of a specific diamond, Diamantes.com recommends consulting with experts and using online valuation tools, keeping in mind that the best investment is one that balances quality and budget, reflecting the buyer’s personal preferences.

Together, the 4Cs provide a systematic way to evaluate and compare diamonds, helping buyers to make informed decisions and sellers to determine fair market prices.
