Diamond Guide

Everything you need to know

Buy with confidence with LeDiamanti

At LeDiamanti, we understand that buying a diamond is an important decision that can sometimes seem complex. That's why we've created this detailed guide to help you navigate through the essential aspects of diamonds, allowing you to make an informed and confident choice.

What is a diamond?

Diamond is a rare gemstone, formed from pure carbon under extreme pressure and heat several kilometers below the Earth's surface. These unique conditions, often found in kimberlites, give diamond its unmatched hardness and exceptional brilliance.

The life cycle of a diamond

Natural diamonds come from deposits located mainly in South Africa, Botswana, Canada, Namibia and Russia. After mining, rough diamonds are often sent to Antwerp for sale and then cut in Surat, India. Once cut, they are certified by gemmological laboratories before being put on the market. This process illustrates the rarity and unique value of each diamond.

The hardness of diamond

Known as the hardest natural material, diamond scores 10 on the Mohs scale. However, despite its hardness, it can break under severe impact, making it important to handle diamonds with care.

Fluorescence and shapes of diamonds

Fluorescence is a characteristic that can affect the perceived color of a diamond under ultraviolet light. As for shapes, each cut (round, princess, oval, etc.) offers unique reflections and aesthetics, suited to different styles and preferences. Discover our diamond collection to explore the different shapes available.

Why have a diamond certified?

Certification by an independent laboratory such as GIA, HRD or IGI guarantees the authenticity and quality of the diamond, detailing its exact characteristics. This transparency is crucial to make a safe purchase.

The 4Cs of diamonds: the key criteria

Carat (diamond weight)

The weight of a diamond is measured in carats, where 1 carat equals 0.20 grams. Each carat is divided into 100 points, facilitating precise measurements such as a 0.50 carat diamond (50 points).

Color (diamond color)

The color of a diamond is graded on a scale from D (colorless) to Z (light yellow). Diamonds graded from D to F are considered the most valuable for their lack of color.

Clarity (diamond purity)

Clarity refers to the presence of internal or external flaws. The purest diamonds, graded FL (Flawless), show no inclusions visible under a 10x loupe.

Cut (diamond size)

Cut influences the brilliance of a diamond. A well-cut diamond reflects light optimally, increasing its brilliance.

Complete Guide to Buying a Diamond at the Best Price

Maximize Your Investment

Les Secrets d’un Diamantaire pour Acheter un Diamant au Juste Prix

Buying a diamond is a big decision, whether it’s for an engagement ring, a luxury piece of jewelry, or a collectible stone. To ensure good value for your money, it’s essential to understand the factors that influence the cost of diamonds. This guide gives you the keys to buying a diamond without overpaying, explaining how to evaluate the price through the 4Cs, certification, and other crucial aspects.

Understanding Diamond Prices

Key Factors

The price of a diamond depends on several factors that together determine its value on the world market, where it is traded primarily in dollars.

  • Carat (Weight): The price increases exponentially with the weight of the diamond. For example, a 0.5 carat diamond can cost between $1,500 and $3,000, while a 1 carat diamond can go for as much as $25,000 depending on its other characteristics.
  • Cut: A perfect cut maximizes the diamond's brilliance, which can compensate for average color or clarity characteristics.
  • Color: Graded from D (colorless) to Z (yellow or brown), a diamond's color affects its price. G or H colored diamonds often offer a good compromise between price and quality.
  • Clarity: Measured by the presence of internal or external flaws, clarity also impacts cost. VS1 or VS2 clarity diamonds are popular options for good value.

Price Ranges per Carat

  • 0.5 carat: $1,650 to $3,500
  • 1 carat: $4,000 to $25,000
  • 2 carats: $19,000 to $70,000
  • 3 carats: $28,000 to $200,000

How to Evaluate the Price of a Diamond

The Importance of the 4Cs

The 4Cs (Carat, Cut, Color, Clarity) are essential to assess the value of a diamond:

  • Carat: Look for diamonds just below popular weights (like 0.90 carat instead of 1 carat) to save money without sacrificing appearance.
  • Cut: The quality of the cut is essential for the brilliance of the diamond.
  • Color: Grades G or H are often the best in terms of value for money.
  • Clarity: A VS1 or VS2 clarity generally offers a good compromise between price and absence of visible defects.

Calculate Price per Carat

The price per carat increases with the size of the diamond. For example:

  • 0.90 carat at $6,000 per carat: Total cost $5,400
  • 0.45 carat at $5,500 per carat: Total cost $2,475
Diamond Certification

Make sure your diamond is certified by a reputable lab like GIA, HRD, or IGI. Certification ensures that the diamond meets the specifications advertised.

Lab-Grown Diamonds: An Economical and Ethical Option

Lab-grown diamonds offer an economical alternative to natural diamonds, while having the same chemical and optical characteristics.

  • Lower Cost: They are generally less expensive than natural diamonds, offering equivalent quality at a lower price.
  • Ethics and Sustainability: Without mining, these diamonds are perceived as more sustainable and traceable.
Buy in Jewelry or Custom-made

Buying a diamond in a custom design can save you up to 30% compared to traditional jewelry stores. Be sure to check the diamond's certification, whether it's natural or lab-grown.
Tips to Maximize Your Purchase

  • Choose diamonds with G or H color and VS2 or SI1 clarity.
  • Prioritize a high-quality cut.
  • Buy online for savings, checking the seller's credibility.
