How to Pick a Diamond: A Step-by-Step Guide
Selecting a beautiful diamond involves carefully balancing the diamond 4Cs – Cut, Color, Clarity, and Carat weight – to achieve the best combination of quality and value without exceeding your budget. The 4Cs of diamonds are the universal standard for evaluating diamond quality. According to the Gemological Institute of America (GIA), “Cut is perhaps the most crucial of the 4Cs.”
Let’s break down each of these crucial elements and guide you through the process of choosing the perfect diamond. Budgets vary significantly, so ensure your spending aligns with your comfort level. For those with a budget around $4,000, explore our article on $4000 diamond engagement rings after reviewing this guide for further inspiration.
We strongly recommend purchasing from reputable online diamond jewelers like James Allen and Blue Nile. Based on our extensive experience, they consistently offer the most competitive prices and widest selection. Their lower overhead costs and lack of traditional brick-and-mortar inventory translate to better deals for you. Both James Allen and Blue Nile provide high-definition 360° imagery, enabling you to closely examine diamonds before making a purchase.
With this essential background, let’s delve into the key steps in the diamond buying process.
1. Choose Your Diamond Shape
The diamond shape is the foundation of your ring’s design and is largely a matter of personal taste. No single shape is inherently “better” than another. Round brilliant diamonds are the most popular choice for engagement rings, renowned for their exceptional brilliance and sparkle.
Expert Tip: While round diamonds are celebrated for their brilliance, personal style is paramount. If you envision a cushion cut halo ring, the brilliance difference between this round diamond from James Allen and this stunning cushion cut might be negligible in the overall aesthetic.
For a more distinctive look, consider shapes like cushion cut diamonds or oval diamonds. If you’re unsure about your partner’s preference, discreetly inquire with close friends or family.
Selecting the diamond shape is the crucial first step as it influences the ideal parameters for cut quality, color, and clarity in the subsequent steps. Choose a shape to refine your search and begin comparing diamonds.

2. Select Your Carat Weight
Is a 1 carat diamond or perhaps a more substantial 2 carat diamond in mind? Or are you seeking a diamond that’s noticeable yet not overly extravagant? The “perfect” carat weight is subjective, entirely dependent on personal preference.
Determine the carat weight range you’re considering, for example, from 0.95 to 1.08 carats. Remember that diamond price increases with carat weight.

Carat weight affects a diamond’s perceived size, as do shape and cut quality. For more guidance on typical carat weights and diamond sizing, consult our guide to average diamond size to inform your decision.
3. Narrow Down on Diamond Cut Quality
Diamond cut quality is arguably the most significant factor in a diamond’s brilliance and beauty. While cut grading isn’t standardized across all retailers, we generally recommend selecting diamonds with an “Excellent” cut grade from the GIA or an “Ideal” cut grade from the AGS.
Utilize the filtering tools provided by reputable online vendors to refine your search to these top-tier cut grades.
For instance, on Blue Nile’s website for round diamonds, focus on “Ideal” and “Astor Ideal diamonds.” On James Allen, choose “Ideal” and “True Hearts” cuts.

Our Expert Advice on Diamond Cut:
For round brilliant diamonds, exclusively search for “Ideal/Excellent” cut grades. However, for fancy shapes, consider including “Premium” cut grades or even disregarding cut grade filters altogether.
This is not to diminish the importance of cut quality – it remains paramount. Rather, it acknowledges that cut grading for fancy shapes is less consistently reported by jewelers. Filtering too strictly might exclude excellent diamond options from your search. Focus on visual inspection and expert opinions when evaluating fancy cuts.
4. Determine the Correct Diamond Color Grade Range
The objective with diamond color is to select a diamond that appears colorless or white to the naked eye. Contrary to popular belief, achieving a colorless look doesn’t necessitate paying a premium for a D color diamond or E color diamond. Diamonds in the G to I color range generally appear colorless to the unaided eye and offer significant cost savings.
It’s crucial to remember that diamond shape influences color perception. Different shapes reflect color with varying intensity. Therefore, the optimal color grade, balancing visual appeal and price, will depend on your chosen diamond shape. For instance, round diamonds are excellent at masking color, allowing you to go slightly lower in color grade without noticing a tint, especially in certain settings. However, shapes like emerald and asscher cuts, with their large facets, tend to show color more readily, often benefiting from higher color grades.

5. Select Clarity Grade
For diamond clarity, aim for an “eye-clean” diamond – one without visible blemishes or inclusions to the naked eye. Depending on the diamond shape, you can often find eye-clean diamonds in the VS1-VS2 clarity range. Paying for a flawless FL/IF clarity diamond is unnecessary when you can achieve the same visual appeal with a lower clarity grade at a much lower price.
Most online jewelers provide high-resolution imagery to assess clarity. James Allen’s “Virtual Loupe” and Blue Nile’s high-quality photography allow you to inspect diamonds closely online. Carefully examine the diamond imagery to check for any visible inclusions.
For a detailed understanding of clarity grades, refer to the diamond clarity scale.
Eye-Cleanliness is Key:
Our primary advice is to find the most affordable “eye-clean” diamond possible (considering clarity, as other factors also influence value). “Eye-clean” describes diamonds that may have inclusions visible under magnification (loupe or microscope) but are not noticeable to the naked eye of a typical observer.
We’ve developed Ringo, a patented AI model, to analyze diamond videos and determine eye-cleanliness. Ringo also assesses cut quality, fluorescence issues, and setting compatibility, streamlining the diamond selection process.
6. Compare Similar Diamonds
Once you’ve defined your desired diamond specifications, compare similar diamonds to determine the best choice. Evaluate factors like brilliance, eye-cleanliness, and price relative to comparable diamonds.

Additional characteristics like fluorescence, polish, and symmetry have a lesser impact on a diamond’s value and appearance compared to the 4Cs. For in-depth information on these aspects, explore our articles on diamond fluorescence, polish, and symmetry.
7. Verify the Certificate
Diamonds are graded and evaluated by independent gemological laboratories. These labs assess and assign grades for cut quality, clarity, color, and other diamond characteristics.
Some labs maintain stricter and more consistent grading standards than others. For reliable diamond grading, prioritize GIA certified diamonds and AGS certified diamonds.
GIA Certificate Verification on Blue Nile:

Avoid certificates from IGI, EGL, and HRD due to our experience with their inconsistent grading standards. Also, differentiate between GIA grading reports and appraisals by GIA gemologists – they are distinct.

James Allen and Blue Nile simplify your search by allowing you to filter specifically for GIA or AGS certified diamonds.
On James Allen, access “advanced options” and select the “GIA” and “AGS” checkboxes:
At Blue Nile, all loose diamonds are GIA-certified, eliminating the need for certificate filtering.
8. Choose an Engagement Ring Setting
Engagement ring settings range from understated elegance, like the solitaire setting, to elaborate and eye-catching designs, such as the halo setting. Each setting style possesses a unique aesthetic and offers distinct advantages.
For instance, solitaire settings are cost-effective and emphasize the center diamond, while halo settings can create the illusion of a larger diamond.
