Selecting the right diamond or gemstone is a significant decision. This guide provides the knowledge you need to make an informed choice, understanding the factors that determine quality and value.
Natural vs. Lab-Grown Diamonds
Both natural and lab-grown diamonds are real diamonds — chemically, physically, and optically identical. The difference lies in their origin and the value considerations associated with each.
Natural Diamonds
- Formed over billions of years deep within the Earth
- Each stone is geologically unique
- Carries inherent rarity and historical significance
- Higher price point reflecting scarcity
- Traditionally preferred for significant occasions
Lab-Grown Diamonds
- Created using advanced technology replicating natural conditions
- Identical in composition to natural diamonds
- More accessible price point for the same quality
- Environmentally considered option
- Certified by the same gemological laboratories
At Artisier, we offer both natural and lab-grown diamonds, each certified by leading gemological laboratories. The choice between them is personal — both create beautiful, lasting jewelry.
The 4 Cs of Diamond Quality
The universal standard for evaluating diamond quality was established by the Gemological Institute of America (GIA). Understanding these four characteristics will help you select a diamond that meets your preferences and priorities.
Cut
Cut refers to how well a diamond's facets interact with light. It is the most critical factor in determining a diamond's brilliance and fire. A well-cut diamond will reflect light internally from one facet to another, then disperse it through the top of the stone.
Clarity
Clarity measures the absence of inclusions and blemishes. Most diamonds have tiny natural characteristics, often invisible to the naked eye. The clarity scale ranges from Flawless (no inclusions visible under 10x magnification) to Included (inclusions visible to the naked eye).
Color
Diamond color is graded on the absence of color. A chemically pure diamond has no hue and consequently, a higher value. The scale ranges from D (colorless) to Z (light yellow or brown). Colorless diamonds allow more light to pass through, creating greater brilliance.
Carat
Carat is the unit of measurement for diamond weight. One carat equals 200 milligrams. While larger diamonds are rarer and more valuable, carat weight alone does not determine a diamond's quality — a smaller diamond with excellent cut, clarity, and color may be more valuable than a larger stone with inferior characteristics.
Understanding Certifications
A gemological certificate is an independent assessment of a diamond's characteristics. It provides objective verification of quality and serves as documentation of your stone's attributes. All significant Artisier diamonds are certified by leading laboratories.
GIA
Gemological Institute of America
The most widely recognized and respected grading laboratory in the world. GIA created the 4 Cs grading system and is considered the gold standard for diamond certification.
IGI
International Gemological Institute
One of the largest independent gemological organizations, with laboratories across the globe. IGI is particularly prominent in the certification of lab-grown diamonds.
IGL
International Gem Lab
Provides detailed gemological assessments with comprehensive documentation of diamond and gemstone characteristics.
CGL
Central Gem Laboratory
Respected laboratory offering thorough analysis and certification services for diamonds and colored gemstones.
Each Artisier piece includes the relevant certification documentation, providing complete transparency about the stones in your jewelry.
Colored Gemstones
Beyond diamonds, colored gemstones offer their own unique beauty and character. Each type has distinct properties and quality considerations.
Sapphires
Prized for their rich blue color, sapphires are extremely durable (9 on the Mohs scale) and available in various colors including pink, yellow, and padparadscha. The most valued sapphires display vivid, saturated color with excellent clarity.
Rubies
The most valued of all colored gemstones, rubies are judged primarily by their color. The finest rubies — described as "pigeon blood" red — command prices exceeding even top-quality diamonds. Rubies are equally durable as sapphires.
Emeralds
Valued for their distinctive green color, emeralds often contain natural inclusions (called "jardin") that are accepted as part of the stone's character. The finest emeralds display a vivid, saturated green without being too dark.
Making Your Selection
Selecting a diamond or gemstone is a personal decision that should balance quality, preference, and investment. Consider these guidelines:
-
Prioritize cut quality
A well-cut diamond will appear more brilliant than a larger but poorly cut stone. Cut has the greatest impact on a diamond's visual beauty.
-
Balance the 4 Cs to your preferences
If size matters most, consider slightly lower clarity or color grades that remain visually appealing. If perfection is paramount, prioritize higher grades in all categories.
-
Insist on certification
Independent certification provides objective verification of quality. Never purchase a significant stone without certification from a reputable laboratory.
-
Consider the setting
The metal color and setting style can affect how a diamond appears. Yellow or rose gold settings are more forgiving of warmer diamond colors.
