I purchased the Fire Light Lab Grown Diamond Stud Earrings when they were a TSV in late January. I received them and the stones are beautiful but to my surprise they do not come with a certificate of authenticity!  I contacted customer service and their response was that the presentation did not state that a certificate of authenticity was included. Foolish me, after spending over $1,000 on a pair of "lab grown" earrings, I just assumed that they would come with the paperwork.  Lesson learned, I am sending back a pair of earrings that I really do love because I have nothing that states that they are genuine lab grown diamonds. I can't be the only one who feels this way? Is there anyone else who is surprised/disappointed  about this issue?

I found this online:

Certification: Each item often includes a certificate of authenticity, and QVC incorporates the Gemological Institute of America's (GIA) expertise into its quality assurance process.

@tiny 2 ……often includes a certificate of authenticity, but not always?🤷‍♀️

@tiny 2.  Most likely for only genuine gemstones.  Don't think the GIA certifies man-made stones.

@JoanneMcK   If you take a jeweler's loupe and examine the stones themselves, you will see that they are laser-inscribed "lab grown".  That is the only way the diamond industry wants them to be sold in the US market, so they can be distinguished from mined diamonds.  Since they are chemically and optically identical to mined diamonds, the potential does exist for a fraudulent  seller to pass off lab-grown stones as mined diamonds and sell them for far more than lab-grown stones would normally sell for.  So far, the labs that grow diamonds are indeed laser inscribing all their stones, so that serves as the authentication.  For instance, I recently took a pair of 1/2 cttw round Fire Light diamond earrings, set in sterling silver, to my local jeweler to be reset in rose gold settings, since QVC isn't selling them that way right now.  I bought the earrings a few years ago, when Fire Light first came to the Q, and they were selling them at a low price, as a sort of "try me".  Before my jeweler printed out the formal intake paperwork for the earrings, she looked at them under a microscope, and remarked that they were indeed laser inscribed with the "lab grown" label.  I suspect that your earrings are, too, if you just take a magnified look.

I have been buying QVC diamond jewelry for decades, and I never once received a "certificate of authenticity."

The item number, and the online description are your guarantee.

In all my years of watching QVC, I call only recall one time QVC even offered a GIA certificate for a special ring with a large center diamond. 

I have diamond jewelry from other places, like Macy's, and the only "certificate" is the price tag. 

I do not buy or wear lab grown diamonds, but I agree that all reputable lab grown diamonds should have a laser inscribed code, or perhaps just the letters LG. 

Yes, GIA does certify lab grown diamonds, but the report they issue is somewhat different from mined diamonds.  You can certainly pay GIA to examine your diamonds and issue a report. However, usually they prefer loose stones.  IGI is another certification company, with a somewhat lesser reputation. 

Lab grown diamonds do not hold their value, and the market is flooded. However, if you like them and enjoy wearing them, that is the main reason to purchase.  Most jewelers I know will not purchase lab grown diamonds back from customers.

"Lab-grown diamonds are primarily certified by

the International Gemological Institute (IGI) and the Gemological Institute of America (GIA). Other reputable labs include the American Gem Society (AGS) and Gemological Science International (GSI). These reports verify the 4Cs (cut, color, clarity, carat) and confirm the diamond is laboratory-grown, often identifying the growth method (CVD or HPHT). 

Key Certification Organizations:

• IGI (International Gemological Institute): Often considered the leader in the lab-grown market, providing detailed, comprehensive reports for both loose stones and finished jewelry.
• GIA (Gemological Institute of America): Provides "Laboratory-Grown Diamond Reports" that use standard, strict grading scales and include, since 2019, a statement that they are not "synthetic".

• AGS (American Gem Society): Known for rigorous, high-quality grading standards.

• GSI (Gemological Science International): A prominent, fast-growing lab that provides widespread certification services. 

What the Reports Include:

• Origin Statement: Confirms the diamond is "laboratory-grown".
• 4Cs Grading: Evaluates color, clarity, cut, and carat weight.
• Growth Process & Treatment: Notes if the diamond was created using HPHT or CVD methods and if post-growth treatments were applied.
• Laser Inscription: The girdle is typically inscribed with the report number and a "Lab-Grown" designation. 

While GIA is often regarded as the industry standard for natural diamonds, IGI is frequently chosen for lab-grown diamonds due to its early adoption and detailed, specialized reporting in this category."

Not from the Q but I bought a pair of lab diamond studs a while back and I love them. Mine came with a GIA certificate and it shows their grade. I did not buy them with the intent of selling them so I don't care that they have lost any resale value. I got them for a very low price when lab diamonds just hit the home shopping networks. Now lab diamonds cost too much for what they are but I think eventually they will come down in price sort of like what Moissanite has done in recent years.

I researched this....may assist (Chat GPT is the source)

Yes — the Gemological Institute of America (GIA) does certify lab-grown diamonds that are sold at places like QVC, but with some important context you should know:

📍 How GIA Certification Works for Lab-Grown Diamonds

• GIA will evaluate lab-grown diamonds – they will confirm the stone is lab-grown and assess its quality. GIA historically graded lab-grown diamonds on the same 4Cs (color, clarity, cut, carat) used for natural diamonds, and still evaluates these stones in various ways.

• However, GIA has changed how it reports lab-grown diamonds: Starting later in 2025, GIA moved away from the traditional detailed 4Cs grading report for lab-grown diamonds and is instead issuing a simplified “quality assessment” that categorizes stones broadly as “Premium” or “Standard” based on combined attributes rather than detailed individual grades.

• GIA still accepts lab-grown diamonds for evaluation and will issue a report or assessment number if the stone meets minimum quality criteria — but the format and depth of the certification is different from classic GIA natural diamond certificates.

📍 What This Means for Lab Diamonds at QVC

• QVC’s lab-grown diamond jewelry (e.g., Fire Light lab-grown collections) is described as made with diamonds judged by GIA standards as part of QVC’s quality process.

• That doesn’t necessarily mean each individual QVC lab-grown diamond comes with a physical GIA certificate, but the diamonds are evaluated against GIA’s criteria and may carry GIA assessment information. Retailers often list the quality details provided by the grading lab on tags or product pages.

🧠 Keep in Mind

• Because GIA’s lab-grown scoring system is evolving and less detailed than before, many lab-grown diamonds in the industry (especially those sold online) are still graded by other labs like IGI, which continues to use the detailed 4Cs grading.

• If having a traditional detailed GIA certificate is important to you, it’s worth asking QVC specifically whether the item you’re buying includes a GIA report number or downloadable certificate, and checking that the certificate matches the stone (via the lab’s database).

Are you planning on selling them later?  Why do you need it?  You sent back an item that you really liked.  I would have kept them.
