What does IKS on the inside of a gold and diamond ring mean? Thanks

IKS’ is the maker’s mark for the Sandeep Diamond Corporation, based in New York, NY.

They use this mark for jewelry containing diamonds, most notably bracelets, rings, earrings, necklaces and pendants.

Of all the marks that could be on your ring, the one that tells the carat weight is probably the most important. Carat weight can be written in a variety of different ways, as there is no standard and each manufacturer has its preferred method. You can commonly see it written as 10k or .417 for 10 karat gold (either white or yellow). 14 karat gold may be written as 14k or .585 (again, either white or yellow).

Carat weights are the second most common stamp in a ring and indicate the weight of the diamond or jewel.

One of the most common questions that gemologists are asked is how to tell the difference between a real diamond and a fake stone. Here are some DIY tests to spot a fake diamond shared by Businessinsider.com:

1. Look at the diamond and setting through a loupe.

A loupe is a magnifying glass that you can buy at any jewelry store and will let you take a closer look at your gem and setting.

As per Reyne Hirsch, a 20th century decorative arts expert and consultant for the global online marketplace Loft, “When you’re looking at a diamond, there are a few things you’ll notice. First, the majority of diamonds are made in nature so that means you’re going to see some imperfections in the carbon. A fake stone would be perfect — absolutely perfect.”

Certain lab-grown stones will also look perfect through the loupe, and so you should be cautious before discarding perfect gems. It can be a clue, however, to take a closer look or bring the stone to an expert.

Second, observe the diamond’s edges. “When you’re taking a look at a diamond through a loupe, a real stone is going to have sharp edges, and a fake stone will have rounded edges,” Hirsch explained.

Lastly, look at the mounting and etchings, especially any marks that signify what metal was used. “If the metal is gold plated or silver, chances are it’s not a diamond because why would you put a nice stone mounted in such a cheap metal?” Hirsch said. “Most diamonds are mounted in gold or set in platinum.”

“Also take a look at the mounting itself and how that diamond is set,” she added. “If the setting looks like it’s of poor quality, that probably means it’s not going to be a real diamond either.”

2. Rub sandpaper against the stone.

This is an easy test since diamonds are one of the world’s hardest materials and won’t be scratched by the rough surface. “If it’s a diamond, it will remain perfect, if it’s a cubic zirconium, it will scratch it up,” Hirsch said.

3. Do the fog test.

Breathe hot air on your diamond the same way you would if you were fogging up a bathroom mirror. A fake diamond will fog up for a short period of time whereas a real diamond will not because it won’t retain the heat.

4. Hold it in the light to see how it sparkles.

The way that diamonds reflect light is unique: Inside the stone, the diamond will sparkle gray and white (known as “brilliance”) while outside of the gem, it will reflect rainbow colors onto other surfaces (this dispersed light is known as “fire”).

A fake diamond will have rainbow colors that you can see inside the diamond.

People have a misconception that diamonds sparkle like a rainbow, but they don’t. They do sparkle, but it’s more of a gray color. If you see something with rainbow colors [inside the stone], it could be a sign that it’s not a diamond.

5. Look at the stone’s refractivity.

Diamonds are so sparkly because of the way they refract and bend light. Glass, quartz, and cubic zirconium may mimic a diamond’s brilliance, but they have much lower refractive indexes.

This means that if your stone isn’t in a setting, you can place it over a newspaper and the light will scatter inside the real diamond and prevent a black reflection. A fake diamond will let the black shine through, and you may even be able to read a word depending on the size of the fake stone.

If your diamond is mounted, make sure you can’t see through it to the mount itself — that’s a very bad sign.

Once you’ve done all your home tests, it’s time to take your jewels that could be diamonds to a gemologist. But don’t just take your diamonds to any old jeweler. It’s important to do your research and find a qualified gemologist, as they know how much they’re actually worth.
