💎 The Diamond Guide | Auvier Fine Jewelry
The Timeless Beauty of Natural Diamonds
Every Auvier diamond tells a story written deep within the earth — a story that took over a billion years to form.
We work exclusively with natural diamonds, each ethically sourced and hand-selected for its fire, brilliance, and character.
At Auvier, we believe a true diamond’s beauty lies not only in how it sparkles, but in what it represents: authenticity, rarity, and eternal love.
1. The 4Cs of Diamonds
Every Auvier diamond is graded according to the 4Cs — Cut, Color, Clarity, and Carat. Understanding these characteristics helps you appreciate the artistry behind each stone.
Cut — The Sparkle Factor
The cut determines how light interacts with the diamond, creating brilliance and fire.
Grades range from Excellent to Poor, with Auvier diamonds always selected for superior light performance.
Auvier Tip: Even a smaller, well-cut diamond will outshine a larger one with an average cut.
Color — The Subtle Shade
Color is graded from D (colorless) to Z (light yellow or brown).
Our natural diamonds are chosen from the near-colorless to colorless range for exceptional radiance.
Auvier Note: Slight warmth in a natural diamond can add vintage depth and individuality — part of its unique charm.
Clarity — The Diamond’s Inner Landscape
Formed under immense pressure, natural diamonds often contain tiny inclusions — their birthmarks from the earth.
Grades range from Flawless (FL) to Included (I), but Auvier’s selections always balance natural purity with stunning brilliance.
Auvier Tip: Many inclusions are invisible to the naked eye — a reminder that true beauty is often perfectly imperfect.
Carat — The Measure of Presence
Carat measures weight, not size.
Auvier curates diamonds across a range of carats, focusing on proportions that enhance sparkle, not just scale.
Auvier Note: Slightly below milestone sizes (like 0.90ct or 1.80ct) often offer better value without visual difference.

3. The Rarity of Natural Diamonds
Every Auvier diamond is earth-mined, ethically sourced, and certified for authenticity.
We do not work with lab-grown or simulated stones — because we believe that true luxury comes from nature’s own craftsmanship.
Natural diamonds are finite — each one a miracle of time, temperature, and pressure that cannot be replicated.
This natural rarity gives Auvier diamonds their enduring emotional and material value.
Auvier Note: The beauty of a natural diamond lies not in perfection, but in its origin — a masterpiece only the earth could create.
4. Certification & Authenticity
Each Auvier diamond is accompanied by an official GIA (Gemological Institute of America) certificate detailing its 4Cs and confirming its natural origin.
This ensures complete transparency, authenticity, and trust — the cornerstone of Auvier’s promise to you.

6. Diamond Care & Maintenance
Diamonds are the hardest known material but still require thoughtful care:
-
Clean regularly with warm water, mild soap, and a soft brush.
-
Store separately to avoid scratching other gemstones.
-
Avoid harsh chemicals, lotions, or extreme temperature shifts.
-
Have your diamond inspected annually by a professional jeweler.
Auvier Note: Even eternal brilliance deserves attention — small acts of care keep your diamond’s sparkle alive forever.
