Is diamond pricing based solely on the 4 C’s of color, clarity, cut and carat weight?

Jewelry Judge Ben Gordon - GIA 4CsWhile the concept of the 4 C’s for diamonds was provided by GIA in 1953, and is a great industry standard today, there are additional factors to consider when pricing a diamond or other gemstone.

For example, the enhancement or treatment of a diamond (and gemstones) must be included as a price factor because it can have a significant impact on the price. Diamond treatments such as fracture filling and high heat + high pressure treatment did not exist prior to the 1980’s, but are common today. As are synthetic lab-grown (man-made) diamonds and look-a-likes, both have much less value than natural earth mined diamonds.

Transparency is also another price factor. Transparency is describes how clear, hazy, cloudy or opaque a gemstone is. It’s a separate factor from clarity. Hardly ever mentioned by retail jewelers, transparency has always been a value factor for colored gemstones, and it can be just as important as color in today’s diamonds.  Non-transparent diamonds are becoming more common in today’s color diamond market.

4CsSalespeople like a quick easy way of presenting gemstone pricing to their customers, so they use the 4 C’s.

February Birthstone – Amethyst

Amethyst Rough and cutAmethyst is not only the February Birthstone, it is also used to celebrate the 6th and 17th wedding anniversary. Amethyst is the perfect color to provide warmth and strength during this winter month.

Amethyst is the purple variety of quartz. While amethyst is most commonly recognized as a purple color, the gemstone color range is a light pinkish violet to a deep purple.

Sometimes, they will have layers of color variations, so the way the gemstone is cut is important to the way the color shows through the top of the finished gemstone.

Amethyst Ring3Amethyst jewelry has been found and dated as early as 2000 BC, and has been associated with many myths, legends, religions, and numerous cultures. Some historical accounts say that Saint Valentine had an amethyst ring carved with an image of Cupid. And for those familiar with Old Testament history, amethyst was one of the twelve gemstones that represented the twelve tribes of Israel.

Is it OK to have an Amethyst Engagement Ring?

Amethyst is appropriate for everyday wear, but its Mohs hardness of 7 means it will show wear over the years and may require re-polishing. Today, consumers make unconventional engagement ring choices, choosing birthstones or other colored gemstones rather than diamond. It’s a personal choice.

 

When looking to purchase Amethyst:

  1. Visit and consult the Jewelry Judge, who is trained and certified to ensure that the consumer gets the best information to make a great purchase.
  2. Check the color of the stone. Amethyst often has “stripes” or layers of color from how and when it was formed, so the cut and polish of the stone is important to show the overall color evenly. Avoid brownish or rust colored tints to the stone and be careful the color is not too deep or it can appear black in some lights.
  3. Look for clarity in an amethyst. Most gemologists will favor a richly colored stone with some minor inclusions (not eye-visible), since the color of this gem is so highly prized. In lighter colored amethysts, visible inclusions will greatly reduce the value of the gemstone.

During early history, amethyst was held to be one of the most precious gemstones, and it was the exclusive choice of clergy as a symbol for the deity of Christ. Today, availability of abundant supplies of amethyst allowed the commercialization and marketing to the general public.  Amethyst’s abundance means the price difference between large and small sizes is minimal, so it is a great gemstone for a statement piece. Larger rings, earrings or pendants can make a great addition to any jewelry collection. Smaller amethysts can be deeply and richly colored, making these pieces pop and get noticed.

Does Where an Amethyst is Mined increase it’s value?
Jewelers and dealers often tell consumers origin matters, because an amethyst from Siberia or Zambia might have a better color than amethyst from Brazil. Origin alone does not add or detract value to amethyst or any gemstone. The Jewelry Judge bases Value on the 4Cs of Cut, Color, Clarity and Carat size, which like diamonds helps determine the quality. Color is the most important value factor regardless of the country of origin for Amethyst and most gemstones.

What’s AAA Quality Amethyst?
Individual companies and dealers often create their own quality descriptions, like AAA, AA, A to denote the range of quality for their goods. No Standard quality grading scale has been accepted by the industry for amethyst or any colored gemstone. The Jewelry Judge uses the 4Cs for Diamonds to guide value for amethyst and all colored gemstones.

What are Enhancements or Treatments?

Gemstone treatments or enhancements refer to the way some gemstones are treated to improve their appearance or durability, or even change their color. Many gemstones are treated in some way (such as heat) to improve their color. The effects of some treatments may lessen or change over time and some treated gemstones may require special care.
Enhancements do affect the value of a gemstone, when measured against a comparable untreated gemstone.

Treatments and/or enhancements should always be disclosed by the seller, along with any special care that might be required. You can shop better by taking the time to learn how to buy jewelry. It can seem like a lot, but with a short consultation with the Jewelry Judge, you’ll be shopping like a professional in no time.

Here are a few basics to get your shopping jump-started:16-SimsBlue

What are natural gemstones?
Natural gemstones come from the earth and are mined worldwide. Some natural gemstones can be enhanced, which means sometimes they are treated in some way (such as heat) to improve their color.

What are imitation gemstones?
Imitation or simulated stones look like natural gemstones in appearance only. This includes tinted glass, cubic zirconia, moissanite or other material that resembles natural stones when treated. Laboratory-created and imitation stones should be clearly identified by the seller, but too often are not.

What are laboratory-created gemstones?
These stones, which can also be referred to as laboratory-grown, manufacturer-created, man-made, or synthetic, have essentially the same chemical, physical, and optical properties as natural gemstones (but not the value). Laboratory-created gemstones do not have the rarity or value of natural-colored gemstones. Although they are similar in many ways to natural gemstones, a professional gemologist like the Jewelry Judge will be able to recognize their difference with proper testing.

Here are four sure fire tips to assure a great purchase:

  1. Compare before you decide. We frequently help couples decide between two or three center diamonds . Often they appear quite differently under the microscope which is almost never on the sales counter in a jewelry store. Local jewelers will often hold a credit card for 24hrs while our clients bring in diamonds for our evaluation. This is called a pre-sale consultation and could save thousands of dollars.
  2. Trust but verify It’s not unusual for us to have a client bring in a $20,000 or $50,000 diamond that was purchased on the Internet. We authenticate and match the stone to the laboratory report that came with the purchase to assure everything is ‘kosher.’ Get a Jewelry Judge Double Check!
  3. Insure before the honeymoon We do not sell insurance, but can show our clients how to obtain no obligation complementary insurance quotes.
  4. Condition Check – Our laboratory instruments can detect small chips or fissures in a diamond that might have occurred during the stone setting process. It’s fairly common to find a chipped corner hidden under a prong that was squeezed to tightly. Jewelry Judge Ben Gordon Double Check

NOROVIRUS IS NOT THE ONLY CRUISE DANGER

Norovirus is an epidemic of gastroenteritis, happening all too often on cruise ships. Limit your exposure by:

  • Washing your hands frequently with soap and water.
  • Washing fruits and vegetables and ensure seafood is cooked thoroughly.
  • When you are sick, do not prepare food.
  • Clean and disinfect contaminated surfaces.
  • Wash laundry thoroughly and machine dry.

Pirate Virus is an epidemic of Tourists easily separated from their money.

Limit your exposure to overpaying for jewelry by avoiding:

Pirate Ploys

  • Inflated List Prices – Nothing says value like a price tag. Pirates inflate “list” prices on the tags, trying to lure you into thinking the jewelry is worth much more than it is. Then if you bargain they will reduce the price and still make a pirate’s profit.
  • Light Makes White – Bright lights make every diamond look better. Pirate shops may have special light bulbs to make a yellowish diamond glisten white.
  • Hide the Flaws – Pirates may hide flaws under the prongs of the setting. Under the prong, an I1 clarity may appear like a more valuable VS2. Learn more about the  4Cs.
  • Grade Bumping – Pirates exaggerate the grade. Pirates will be INACCURATE by one or two color and clarity grades since you do not know which lab definitions they use. Pirates like to provide a range, such as G-H color.
  • Laser Drilling – Pirate diamonds may have drill holes to hide dark carbon impurities and enhance the diamond clarity when viewed by the naked eye.
  • Fracture Filling – Pirates use inexpensive fracture filled diamonds, which make the flaws invisible, but the diamond is unstable and likely to break.
  • Synthetic Diamonds – “Natural” Lab Grown diamonds are everywhere! Especially on pirate ships where synthetics may get mixed-in with natural mined diamonds. Learn more about Synthetics.
  • CZ, Quartz or Moissanite – Diamond look-a-likes “simulants” can fool you and every pirate knows it. You might come home with a $12 cubic zirconia that cost you $2,000. It is amazing how these look-a-likes get mixed into pirate jewelry.
  • The 50% Off Sale – Pirates love Huge Sales (don’t you?). Don’t fall for it, pirates mark up everything, then mark them half-price during a sale. Liquidation and “going out of business” sales use the same ploy.

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!
