Consumer Alert: Synthetic Diamond Prices Crashing

Nov 21, 2023

Consumers Beware. Synthetic diamond prices are crashing yet some retailers are pricing them high by comparing them to prices for natural diamonds. Consumers think they are getting a good deal, but they are not. Synthetics trade as low as 98% below the Rapaport Price List for natural diamonds.

Synthetic prices are all over the place. Walmart sells a 3 ct., Round, F-G, VS1-VS2, synthetic diamond solitaire ring for $2,975, while Signet’s Blue Nile sells a similar 3.00 ct., Round, G, VS1 synthetic diamond solitaire ring for $8,190. That’s a 275% difference for the same ring.

Some jewelers are pushing synthetic diamonds because they can make huge profit margins. This won’t last because synthetic diamond prices are crashing to hundreds and even tens of dollars per carat. This is because they are available in unlimited supply.

Whether or not to buy a cheap diamond as an engagement ring is a consumer preference. However, consumers who spend thousands of dollars on synthetic diamonds may be seriously overpaying.

Consumers should be aware that synthetic diamonds are not like natural diamonds which are rare and expensive. Synthetic diamonds are not real diamonds. They do not retain value. are not real diamonds and are not a store of value.

My Consumer Alert on the crashing prices of synthetic diamonds made quite a splash. It generated numerous positive responses, along with backlash from those questioning my motives, my integrity, and even my relevance after 46 years in the diamond industry.

I will now begin a series responding to the most common questions on my Consumer Alert, sharing data and facts that may challenge the skeptics to reconsider.

But the first question is more about my personal opinion.

People asked me: Why do you hate Lab diamonds?
My answer: I don’t.

I love them… for costume jewelry.

With their brilliant sparkle and lower price point, they’re perfect for flashy fashion jewelry that will be enjoyed today and set aside when the next trend arrives.

My problem starts when synthetic diamonds are presented and priced as fine jewelry. I especially don’t like when they are marketed as ideal for engagement rings, or other jewelry that symbolizes lasting love.
True love is precious, synthetic diamonds are cheap (and getting cheaper every day).

Your engagement ring, an heirloom that you and your family will treasure forever (God willing), deserves to be worth more than the dinner you were eating when it was presented to you!

No, I don’t hate synthetic diamonds.

What I do hate is the misinformation surrounding their value. I can’t stand that so many consumers might overpay for them this holiday season.
I abhor the possibility that, very soon, today’s buyers will realize that they’ve been duped by the jewelry industry.

Sellers of synthetic diamonds often present themselves as the champions of the budget-conscious jewelry shopper. “I’ll get you more bling for your buck!”So far, uninformed consumers have been buying it.

In the business world, we have a more sophisticated understanding of margins and revenue.
Current exorbitant markups on synthetics make them a bad deal for shoppers.

Many argue: “People want synthetics because real diamonds are overpriced.”
The reality is the opposite.

Retail markups on natural diamonds range from 12%-39%. In dazzling contrast, the markup on synthetic diamonds is at least 10 times greater, reaching an astronomical 611%.

This is clearly a bubble. Synthetic prices are crashing. Consumers who pay thousands for overpriced synthetics this holiday season are getting a raw deal.

Synthetic diamonds and natural diamonds, we are told, share identical physical properties. Does that mean they are the same?

Absolutely not! One proof is that we can tell them apart.

Synthetic diamonds are not real diamonds.

The Federal Trade Commission warns:

§ 23.24 It is unfair or deceptive to use the word “real,” “genuine,” “natural,” “precious,” “semi-precious,” or similar terms to describe any industry product that is manufactured or produced artificially.”

  1. Dear Sir,

    I have one comment on your comparison of pricing of Walmart and Signet Blue Nile. Is it not the same for natural diamond too when it comes to different brands of jewelers. It is not that all rings of 1 carat natural solitaire diamond of same attributes have same pricing across all brands.


  2. You state that a synthetic diamond is not a diamond. But yet it possesses all the same chemical, physical, and optical properties of a diamond. With any newer item that hits the market there will be price fluctuations depending on supply and demand along with lowering manufacturing costs. Having over 40 years in the jewelry trade I have seen many changes over the years. There will be two distinct markets going forward because the price of natural diamonds have become out of reach for many prospective buyers. To criticize, instill fear, or shame a prospective client for buying synthetic diamonds is a bullying and disgusting tactic. The client is there to buy a special gift for a loved one and should be treated as such. Store owners need to supply what each and every client wishes to spend their hard earned money on. Diamonds are not rare the price is simply manipulated and kept artificially propped up by the Debeers Consortium. If synthetic diamonds were a flash in the pan then why is GIA giving out reports on them? The person above my post makes the perfect point. I can spend 15k at Tiffany’s or 5k at Costco it’s still the same diamond. The diamond market was exactly the same before there was a
