# The 4Cs of Diamonds: The AVA ROSSA Guide to Choosing the Perfect Stone

When you choose a diamond, you are not just choosing a precious stone — you are choosing a story that will last a lifetime. At AVA ROSSA we believe every client deserves to truly understand what lies behind the sparkle of a diamond, beyond appearances. That is why we have prepared this guide to the 4Cs — the international standard by which every authentic diamond is assessed: **Cut, Clarity, Color** and **Carat**.

## 1. Cut — The Soul of the Diamond

Of all the 4Cs, cut is the only factor determined entirely by human hand and skill — and, experts say, the most important for a diamond's brilliance. An impeccably executed cut allows light to enter the stone and be reflected back to the eye in a spectacular play of light, known as "fire" and "scintillation".

A diamond cut too deep or too shallow will let light "escape" through the bottom of the stone, resulting in a dull, lifeless stone — no matter how pure or large it may be. Cut grades range from Excellent to Poor, and at AVA ROSSA we select only diamonds with an Excellent or Very Good cut, guaranteeing the distinctive brilliance that defines our collections.

## 2. Clarity — Nature's Fingerprint

Every natural diamond carries tiny internal inclusions or surface characteristics, formed deep within the earth millions of years ago. Clarity measures the absence of these natural "fingerprints", on a scale from FL (Flawless — no inclusions visible even at 10x magnification) to I (Included — inclusions visible to the naked eye).

The good news? Most inclusions are invisible to the naked eye and do not affect the beauty of the stone. At AVA ROSSA, our team selects diamonds with VS (Very Slightly Included) clarity or higher — offering perfect visual clarity, with no compromise on the value of your investment.

## 3. Color — Discreet Refinement

For classic white diamonds, the less colour is present, the more valuable and rare the stone. The international scale starts at D (absolutely colourless) and runs down to Z (visible shades of yellow or brown).

The difference between a D and an H diamond, for example, can be imperceptible to an untrained eye, but it has a significant impact on price. At AVA ROSSA, we work with diamonds in the D-G range — the optimal zone where colour purity meets balanced value, ideal for our 14K and 18K gold pieces.

## 4. Carat — Beyond Size

Carat is perhaps the best-known of the 4Cs, but also the most often misunderstood. A carat is a unit of weight (0.2 grams), not of size — two diamonds of the same carat weight can look noticeably different depending on the cut and the shape of the stone.

It is tempting to chase the biggest number, but a smaller diamond with an excellent cut, high clarity and refined colour can shine far more beautifully than a large but poorly cut stone. At AVA ROSSA we guide you to find the perfect balance between the 4Cs, according to your budget and your story.

Why the 4Cs Matter at AVA ROSSA

Every piece in our collections is crafted from 14K or 18K gold and set with certified natural gemstones, rigorously verified against this international standard. We do not choose diamonds only for their size, but for their balance — for that rare combination in which each of the 4Cs supports the others, creating a truly memorable stone.

An AVA ROSSA diamond is not just a piece of jewelry. It is a certainty: the certainty that, beyond the sparkle, there is authentic, certified and carefully selected quality — for the moments that matter most🤍
