Diamond Buying Guide: 4Cs, Certifications, and What to Avoid

Being aware of the 4Cs of a diamond, guaranteed purity, and trap situations can enable you to make a smart and deserving investment. Let us discuss these aspects in detail.

1. Knowing the 4Cs of Diamonds

The 4Cs: Cut, colour, Clarity, and Carat are the global criteria for determining the quality and price of a diamond. They all impact the appearance, brilliance, and value of a diamond.

Cut: Determines brilliance and fire

Cut is also known as the most important one because it makes a diamond look brilliant and shiny.

• Ideal Cut: Achieves maximum brilliance with perfect proportions.
• Deep Cut: Dulls brilliance by limiting light.
• Shallow Cut: Let’s light escape, reducing brilliance.

VBJ Tip: Utilise cut quality instead of carat weight to achieve maximum sparkle. A properly cut diamond will be brighter, although smaller.

colour: From D (colourless) to Z (yellowish colour)

The diamond’s colour varies from D (completely colourless) to Z (obvious yellow tint). The more colourless, the more valuable and the more rare the diamond.

• DF (colourless): Top quality and most costly.
• GJ (Near colourless): Slightly warmth but still pleasing.
• KZ (Noticeable Tint): More yellow cast, usually lower-cost.

VBJ Tip: GJ near colourless diamonds are a steal, looking bright to the naked eye but without the cost of a completely colourless diamond.

Clarity: Grading imperfections (inclusions and blemishes)

Clarity determines the presence of natural imperfections (inclusions in the diamond and blemishes on the surface).

• Flawless (FL/IF): No flaws visible under 10x magnification.
• VVS1VVS2 (Very Very Slightly Included): Essentially flawless.
• VS1VS2 (Very Slightly Included): extremely small inclusions, not visible to the naked eye.
• SI1SI2 (Slightly Included): small imperfections that can be viewed under magnification.

VBJ Tip: VS1 or VS2 diamonds offer clarity at a reasonable cost. Most of the inclusions are not visible to the naked eye, therefore these grades must be taken into consideration.

Carat: Spelling applied to diamond weight, not diameter

Carat weight will determine the diamond’s size and not its quality.

• 0.50:1.00 carat: Ideal solitaire ring size, providing brilliance and value.
• 1.00:2.00 carats: Traditional engagement ring size, providing luxury.
• 2.00+ carats: Expensive large stones with scarcity.

VBJ Tip: Rather than paying attention to carat weight alone, make sure your diamond is well-cut to reflect a bright appearance. A well-cut 1carat can look larger and whiter than a poorly cut 2carat.

2. Diamond Certifications: Why They Matter

A diamond certificate is crucial to verify the gem’s authenticity, quality, and ethical origin. Accurate appraisals from reputable diamond grading labs enable consumers to make sound decisions.

GIA (Gemological Institute of America) : Most reputable grading agency

GIA is the benchmark for diamond grading with rigorous examination of the 4Cs. GIA certification guarantees your diamond was evaluated in a unbiased setting, ensuring quality, transparency, and legitimacy.

AGS (American Gem Society) : For precise cut grading

AGS is also a very well-known grading lab, with thorough examination of cuts along with colour, clarity, and carat grading. They possess highly precise scales, especially for determining the light performance of a diamond.

IGI & EGL : Also very well-known certification agencies

• IGI (International Gemological Institute) : Very well-known for grading the diamonds that are sold in Europe and Asia.
• EGL (European Gemological Laboratory) : Reports extensive diamond analysis but is less critical than GIA or AGS.

VBJ Tip: Always request a grading report to guarantee diamond quality before buying. GIA or AGScertified diamonds provide more accuracy and reliability than other laboratories.

3. Common Errors to Avoid When Purchasing Diamonds

Purchasing a diamond is a big investment, and smart choices provide the best value and quality for money.

Paying too much

Prices dramatically differ with the brand, certification, and retailer practices. Consumers compare diamonds at various vendors and scan their online ads so that they get fair prices.

VBJ Tip: If two diamonds are equally graded 4Cs but one is costlier, check for unnecessary brand premiums or overpaid prices.

Not Reading Grading Reports : Don’t Buy GIA or AGScertified diamonds.

Some merchants offer inferior diamonds or inferior grading organisations, which exaggerate quality grades.

VBJ Tip: Always ask for a GIA or AGS report when purchasing to avoid overpaying for lower-quality diamonds.

Overlooking Ethical Sourcing : Purchase conflict-free diamonds

Not all diamonds are conflict-free, and conflict diamonds (also called blood diamonds) pay for inhumane actions.

VBJ Tip: Choose Kimberley Process certified diamonds, and ensure your diamond is sourced ethically.

Wrong Shape or Setting : Match diamond shape to a practical setting

Diamond shapes fit certain ring settings and styles.

• Round brilliant : Most popular cut with most brilliance.
• Princess cut : Low profile edges and contemporary style.
• Oval & emerald cuts : Elegant elegance, stretching fingers.

VBJ Tip: Consider your lifestyle, tense fingers might prefer secure fit styles like bezels, while those who love sparkle will enjoy prong settings.

Skipping Certification : Always verify with proper documentation 

Buying an uncertified diamond can lead to a lower resale value and uncertainty regarding quality.

VBJ Tip: Always purchase diamonds with official grading reports to be transparent and confident.
