What Type of Diamond Do You Have?

Do you want a Natural diamond, a Synthetic diamond, or a Simulant?

Whether you are looking for BLING, an investment, expressing your love, saving money or saving the environment, your choice of gemstone is a personal thing. As long as you know what you are getting, you can enjoy your purchase. There is nothing worse than being misinformed during your engagement ring hunt!

Here are a few things you need to know:

  1. Diamond Simulants — mimic the look of diamonds and include cubic zirconia, moissanite, quartz, and glass, just to name a few. Simulant Retail Value approximately $200 per carat or less.
  1. Synthetic Diamonds — laboratory-created, lab-grown, or man-made diamonds have the same physical and chemical properties as mined diamonds. Synthetic Retail Value is approximately 20 to 50 percent less than mined diamonds, but varies greatly between manufacturers and the size/color of the synthetic diamond. Synthetic Diamond Grading Reports are being issued by gemological laboratories. These reports provide no guarantee and no recourse.


You won’t be able to tell the difference between a natural mined diamonds a simulant or a synthetic lab-grown diamond. With Gem Lab Equipment, Our Experienced Graduate Gemologists Know the Difference.

 3. Natural Diamonds – refers to diamonds made through geologic processes, taking hundreds of millions of years to form. Only 30 percent of diamonds that are gem quality, bright and beautiful, end up in jewelry, the rest are only good for industrial uses.

The four Cs made up of the color, the clarity, the quality of the cut, and the carat weight of the diamond have the greatest impact on the value and price. Know the 5th C – Confidence comes with a Jewelry Judge Appraisal Report!

Why The Eternal Slogan has Lasted so Long…

Ever wondered who came up with the brilliant (no pun, of course) slogan, “A Diamond is Forever?” Would you believe, it’s only been around since 1948? De Beers was experiencing a post Depression era slump in sales. Since then, the slogan is identified with emotion and longevity, love and immortality – representing a major change in advertising concepts that promote the feelings about a product, not the product itself. If you enjoy the psychology of sales and, of course, the glitter of diamonds, read the full article appearing in The Washington Post …. .


Germs – Not the Only Danger of Cruise Vacations

Clients come to us after a cruise vacation to obtain insurance appraisals on the jewelry they purchased. This story almost NEVER has a happy ending! We will continue to document cases like the following…

Our client traded her diamond earrings with .80 ctw stones (SI) for 1.75 ctw diamond earrings (I-2). That’s right I-2/3. Remember I stands for Inclusion. A clarity grade of I-2/3 means the diamond is of industrial quality – not worthy of fine jewelry. But this is not the most painful issue.

In addition to surrendering her pretty earrings, she paid an additional price of $20,000 for the privilege of purchasing the larger, but inferior quality earrings. Yes, size does count, but quality should trump size in most diamond purchases.

Is it a crime if you GIVE your jewelry and money to a Pirate? Maybe it’s not illegal, but is sure is a shame!

How could we appraise low quality stones for their replacement value when the client overpaid by thousands of dollars – maybe even tens of thousands? This is a real dilemma for appraisers and insurance companies as well.

Have fun with the costume jewelry and souvenir purchases and enjoy the vacation. Put the money you save from the diamond purchase toward another holiday! But please beware when buying diamonds while on a cruise!

Trust But Verify

Verification is what we do in our gem lab on a daily basis. Often the paperwork or certificate from a gem lab does not match the stone that accompanies it.

We ‘call them as we see them.’ This past week we examined a diamond ring with a certificate grade for the stone of SI-1. While we agreed with the color grading, we determined the clarity to be SI2 – 3. This meant that the owner had received a lesser quality stone than he thought he was buying.

With the information we provided, he was able to return the stone to the jewelry retailer in exchange for a better quality stone with a GIA certificate – the more trusted grading laboratory.

This type of discrepancy happens more and more frequently so Buyer Beware – Trust but Verify. Here is a helpful link to a news network broadcast:

As appraisers, we see cut and polished stones but the gems in the rough are fascinating as well. Hear comments from the field before sapphires reach the cutters.
