GEMSTONE GUIDE
More than an ornament
A gemstone is more than an ornament — it is a set of characteristics that define its appearance and value. At ANELI Antwerp, we believe every choice should be an informed one. This section helps you understand the differences and see what truly matters.
DIAMOND GUIDE
The 4C Principle (Cut, Clarity, Colour, Carat)
A diamond's quality is determined by a combination of factors. Even slight differences in its characteristics can significantly affect its appearance. Understanding these parameters allows you to make a precise and informed choice.
Diamond Cut
The cut determines how the stone interacts with light. It is responsible for the diamond's brilliance, depth, and "life."
Diamond Clarity
Clarity measures the degree to which a stone is free from internal and external inclusions. Even minimal differences can significantly affect its appearance.
Diamond Colour
Diamond colour ranges from completely colourless to warmer tones. The difference is often invisible to the untrained eye, yet it affects the value.
Diamond Carat
The weight of the stone affects not only its size but also the perception of the piece. It is important to consider the balance between weight and other characteristics.
Certification
Certification confirms the properties of the stone and its authenticity. We work with GIA and HRD Antwerp.
COLOURED GEMSTONE GUIDE
Unlike diamonds, coloured stones are evaluated by different principles. Here, colour, saturation, and natural characteristics play the leading role.
Colour
The key parameter for sapphires, emeralds, and other stones. The depth and evenness of colour define their value.
Saturation
The intensity of colour shapes the visual perception of the stone. More saturated tones are considered rarer.
Origin
Certain regions are renowned for high-quality stones. This can affect rarity and price.
Rare Stones
Beyond the classics, there are unique varieties — such as Paraiba or spinel. They are highly valued for their rarity and character.
HOW TO CHOOSE A STONE
Choosing a stone is a balance between characteristics, budget, and visual perception. Our gemologist helps explain the differences, define priorities, and find the optimal solution.
