How to verify the quality of lab-grown diamonds

I’m excited to guide you through the process of verifying the quality of your newly purchased lab-grown diamonds. These straightforward steps will give you peace of mind and confidence in your investment.

  • Examine the Certificate: First and foremost, make sure your lab-grown diamond comes with a certificate from a reputable organization like GIA, AGS, or IGI. This certification vouches for the quality and authenticity of your gemstone.
  • Assess the 4Cs: Get acquainted with the four critical diamond characteristics: carat weight, cut, color, and clarity. These factors establish the overall quality and value of your lab-grown diamond. Compare the diamond you received with the information on the certificate to confirm its quality.
  • Inspect Your Diamond Closely: Utilize a jeweler’s loupe or microscope to examine your lab-grown diamond for any inclusions, blemishes, or imperfections. Ensure the diamond’s overall appearance matches the retailer’s description and images.
  • Verify the Girdle Number: Reputable diamond grading labs like GIA, IGI, and AGS engrave a certificate number on the diamond’s edge or girdle. This unique number links your diamond to its grading report. Use the lab’s online report check feature to verify your diamond engagement ring by entering this number on their website. Although the inscription is invisible to the naked eye, some retailers, such as James Allen, even provide a diamond loupe in the box for your convenience.
  • Consult a Trusted Jeweler: If you need more clarification about your lab-grown diamond’s quality, seek a second opinion from a reliable jeweler. They can professionally evaluate your diamond and provide expert guidance, bolstering your confidence in your purchase.


By following these steps, you can easily confirm the quality of your lab-grown diamond and know that you’ve made an intelligent choice.

How much should I spend on a lab diamond?

Let’s explore how much to allocate for a lab-grown diamond purchase. While no universal answer fits everyone, several factors can help determine your budget for this significant investment. By understanding these factors, you can establish a realistic budget and identify the best option that aligns with your preferences.

Personal Finances:

Your financial situation is the most critical factor to consider. Establish a budget that takes into account your individual circumstances and ensures you’re comfortable with the amount you’re investing in a lab-grown diamond.

Size and Quality:

Lab-grown diamonds come in various sizes and quality levels, directly influencing their cost. Familiarize yourself with the 4Cs (carat weight, cut, color, and clarity) to comprehend how these factors affect a diamond’s price. Generally, larger and higher-quality diamonds carry a higher price tag, so consider your preferences and prioritize accordingly.

Setting and Design:

The diamond’s cost is just one aspect of the overall price. The setting and design of your chosen piece will also contribute to the final cost. Decide whether you prefer a simple or intricate design, and incorporate this into your budget.

Remember that different retailers offer engagement rings at varying prices, and the choice of material will also affect the cost. For instance, platinum settings are less affordable than 14K white gold.

Know Your Limits and Set Realistic Expectations:

Conduct brief research and filter your options based on your budget to understand what you can afford and what’s unrealistic. Generally, you have three options: buy the largest diamond within your budget, strike the best balance between all factors, or compromise on carat weight and opt for a smaller diamond with maximum brilliance, fire (blue and yellow reflections), and sparkle.

Remember to purchase the most beautiful diamond within your budget and avoid exceeding your financial limit.

Two Months' Salary Rule:

Some people adhere to the “two months’ salary rule,” suggesting you allocate the equivalent of two months’ income for a diamond purchase. However, this is merely a guideline, and it’s crucial to set a budget that suits your individual financial situation and preferences.

In conclusion, determining how much to spend on a lab-grown diamond depends on your personal finances, preferences, and priorities. Consider the abovementioned factors, and set a budget that feels comfortable. Remember, a lab-grown diamond symbolizes love and commitment, so focus on finding a piece that genuinely reflects your unique story and relationship.

Why low prices aren't always the best

You might wonder, “Why haven’t you mentioned websites like With Clarity, Clean Origin, Lab-grown Brilliance, and other lower-tier retailers?” Well, my answer is simple.

While the competitive market allows these smaller retailers to offer seemingly “identical products” at lower prices, you may compromise on other aspects. Customer service, diamond quality, and overall buying experience are not on par with those provided by our recommended vendors.

Opting for a cheaper price could come with hidden costs and risks. Personally, I’d rather pay a bit more and have the peace of mind of knowing I’m in good hands. Moreover, if any issues arise with my diamond, I know someone will be available to help me.

Conclusion - My Personal Experience

Whenever someone inquires about where to purchase their lab-grown diamond engagement ring, James Allen is the first name that springs to mind. Undoubtedly, they currently stand as the ultimate choice, checking all the essential boxes.

They have earned their reputation as a legitimate company with a solid background, exceptional customer service, and policies that ensure you’re covered for any issues that may arise. However, the real game-changers are their competitive prices and the industry-leading 360-degree videos.

People reach out to me daily through my contact page, seeking help choosing a diamond. Sometimes, they send me a link to a diamond from an unfamiliar website, accompanied by a low-quality video. It would be unprofessional for me to work with such a website and jeopardize your hard-earned money, even if they offer tempting low prices.

James Allen provides the best customer experience, allowing me to rely on my expertise and keen eye to select the finest diamonds without risking my reputation. For newcomers like yourself, their videos offer peace of mind, ensuring that what you see is precisely what you get. There’s no need to be a diamond expert—simply recognize what looks beautiful and what doesn’t.

While many diamond retailers have approached me, I hold the highest standards, choosing to collaborate only with those whose services and pricing I can confidently endorse. Your satisfaction and access to quality service are my top priorities. Therefore, you can trust that I maintain an unbiased perspective, without compromising the integrity of this blog.
