How To Buy Pearls

Fine pearls are one of the least understood and most niche gemstones in the jewelry world – even professional jewelers often run into trouble identifying pearl types, understanding grading scales and pearl value.

It’s not surprising then that there are a number of questions that need to be answered before taking the plunge and investing hundreds or even thousands of dollars into a fine pearl necklace or pair of earrings.

You probably already have an idea of what kind of jewelry you want to buy (i.e. pearl necklace, earrings, full set, etc.), so let’s focus on how to choose the right pearl type first before looping back into jewelry designs, budgetary issues and finally, selecting the right vendor where to buy pearls.

STEP 1: Choosing the Right Pearl Type

So, you’ve decided that you’d like to buy a fine pearl necklace (or a pair of earrings), but now you’re stuck: what kind of pearl necklace should you buy??

There are 4 main pearl types to choose from:

  • Japanese Akoya Pearls
  • Chinese Freshwater Pearls
  • Tahitian Pearls from French Polynesia
  • White or Golden South Sea Pearls from Australia and the Philippine Islands

Each one of these has its own unique beauty, size ranges, pearl color and budget parameters.

Let’s deal with the most frequently asked question first as it deals with the two most popular (and easily confused!) white pearl types.

Should you buy Akoya pearls or Freshwater pearls?

  • Choose Freshwater Pearls If ...
Reasons to Buy Akoya Pearls
  • Your budget is $350 & up to purchase the Classic White Pearls you've been dreaming of.
  • Perfectly Round pearls and Bright, Excellent Luster matter a lot to you.
  • Only that traditional "Mikimoto" style of pearl jewelry will do.
  • You want elegant "high-end" pearls for special occasions.

Reasons to Buy Freshwater Pearls
  • Your budget is $350 & under but you still want a pretty white pearl necklace.
  • You want an everyday strand of pearls. Freshwater pearls can easily stand up to hot days, children's sticky fingers, perfume office meetings and more.
  • You're worried the pearls may be handled roughly and/or lost. Lower price points make these relatively easy to replace.
  • Slightly off-round shapes and softer glow don't matter as much as long as the jewelry gives an overall impression of fine white pearls.

As mentioned earlier, the other main pearl types are black Tahitian pearls, and White or Golden South Sea Pearls – what I call our “Exotic Pearls”. Each variety is wonderfully distinctive, with its own traditional pearl colors, size ranges and unique beauty.

STEP 2: Choose the Perfect Pearl Size

Pure Pearls offers TONS of advice and real-life pictures of our pearls actually being worn on models so you know how your pearls are going to “measure up” when they arrive.

Generally the most popular sizes are within the 7.0-9.5mm range, which are considered the most traditional and versatile pearl sizes to buy.

The larger the pearls get (all other attributes like Luster, Shape, and Surface Quality being equal), the more valuable they are.

Check out:  Pure Pearls Ultimate Pearl Size Comparison Guide.

Inside you’ll find a complete range of traditional pearl necklace and earring sizes modeled for you so you know what to expect, a “Pearl Sizes in Real Life” printable PDF you can keep, and a complete breakdown of each pearl type’s size ranges from Akoya to South Sea pearls.

STEP 3: Select the Right Necklace Length

DEFINITELY visit:  Pure Pearls Ultimate Guide to Necklace Lengths  to learn everything you could ever need to know about pearl necklaces – from the timeless classics to more modern styles!

Pro-Tip: The most popular and versatile pearl necklace length is called the 18-Inch “Princess Length” pearl necklace.  This is considered the “Modern Classic” length, and should come to rest about 1.5 to 2.0-inches below the hollow of the throat – suitable for a wide variety of necklines and outfits.


STEP 4: Set Your Budget

For fine cultured pearl jewelry, you should set a baseline of $100 or so for even the smaller-sized Akoya pearl stud earrings mounted in 14K Gold, and the same can be said of fine Freshwater pearls.

Setting the Right Budget for Fine Pearl Jewelry

Each pearl type has its own pricing tiers, and much like diamonds, you can expect prices to increase exponentially with every millimeter size increase. The price difference between a 7.0-7.5mm Akoya pearl necklace, and a 9.0-9.5mm size is quite large.

A good rule of thumb is to expect a 30-50% increase in price with each millimeter size up you go.

This pricing issue is due to a variety of factors, with  rarity  chief among them.

Larger pearls require much more time acquiring thicker nacre layers in the host oyster, and the amount of risk, time and labor that goes into culturing a single 15.0mm fine quality South Sea pearl (for example) is quite a lot ...

Freshwater pearls are very budget friendly, with low to mid-range pricing tiers from just a few dollars to the low thousands for the very largest and finest styles.

STEP 5: Pearl Grading and Pearl Value Factors (there’s 7 of them)


STEP 5: Understanding Pearl Value Factors

Grading Pearls and Understanding Value Factors

Understanding these points is  CRUCIAL.

The main pearl grading factors are:

  • Luster - this makes or breaks pearls as a gemstone. Luster describes the way light reflects off the pearl surface (Sharp and Highly Reflective or Soft and Blurry). The sharper the Luster, the more valuable the pearl.
  • Surface Quality - pearls with smooth, clean surfaces are more highly valued than those with multiple inclusions.
  • Symmetry of Shape - truly round pearls are the rarest shape of all, and the most valued. After that, we look for perfectly symmetrical semi-baroque shapes like tear-drops and ovals, then circled baroques and finally, free form baroques which are totally asymmetrical.
  • Color - pearls come in every color of the rainbow (literally!). This value factor is weighted according to whether the color is naturally-occurring, the depth and saturation of the color, and the rarity of the color.
  • Size - large, perfectly symmetrical pearls are RARE, taking many years to form inside the oyster. If all other value factors are equal, the larger pearls will be the more valuable ones.
  • Origin - The value of cultured (farmed) pearls that dominate the industry today vary by pearl type: Freshwater (least expensive), saltwater Akoya (mid-range), black Tahitian (mid to high-range pricing) and South Sea (highest). We also factor in whether the pearl is cultured or natural / wild. Natural pearls - pearls that are formed without any human assistance - are extremely rare and command premium pricing.
  • Matching - The meticulous matching of a fine pearl necklace layout can take many years depending on the pearl type. You're looking for a steady, smooth graduation rate from smallest to largest pearls in the center, with little to no variation from pearl to pearl in terms of Luster, Shape, Color, Overtone and Surface Quality (Multi-Color strands are given a tad more leeway but still must have an overall well-matched "tone").

To this date, there’s still no set, internationally agreed-upon grading scale for pearls. That means that pearl grading is subjective, depending on the seller you’re dealing with.

PurePearls.com uses the A-AAA Grading Scale, which is a simple and straight forward grading system based upon specific percentages for attributes like surface blemishing, luster rating (the sharpness of reflections), color/overtone and shape, among others. The A-AAA scale is used most commonly with Akoya and Freshwater pearls, but also converts easily from the Tahitian and South Sea grading scales.

If you don’t want to end up with an over-priced strand of pearls (or pearls that have heavy blemishing or a chalky appearance), then it’s important to understand what each pearl type should look like, and what benchmarks it needs to meet on the A-AAA Grading Scale.

If you see a strange grade like AAAA+, then buyer beware.

For an in-depth understanding on each pearl’s grading scales read: The Insider’s Guide to Pearl Grading

Don't Forget About Pearl Luster!

Akoya Pearl Luster Close UP

Lustrous pearls are prized pearls.

The deeper and more intense the luster is, the more valuable the pearl. Look for pearls that display reflected light sources as crisp, clean and delineated, with only slight blurring around the edges.

You should also be able to recognize some of your facial features reflected in the surface of the pearl. AAA quality pearls feature the best luster, AA+ quality pearls should have Very High luster and so on.

STEP 6: Finding the Right Vendor

Fine pearl jewelry is a gift that’s meant to touch the heart. The vast majority of the time, these gems are going to be a very special surprise for a birthday, anniversary, graduation or Holiday event.

Because this purchase is such a special one, there are a few considerations to take into account before settling on a vendor to purchase from. A few Dos and Don’ts to remember before taking the plunge:

Pearl Buying Dos and Don'ts

Choosing the right vendor should balance pearl selection, quality, price and above all, excellent Customer Service.

While Mikimoto definitely does carry beautiful quality pearls, doing a little bit of homework can save you THOUSANDS by avoiding the high premiums charged by luxury brands without sacrificing quality.

On the flip side, shopping by price alone without knowing what you’re buying (or whom you’re buying it from!) is a one-way ticket to frustration. Taking the plunge on an anonymous overseas vendor could net you a strand of potato pearls for way more than they’re worth and no way to return them.

Fraud eBay Pearl Jewelry Purchases

Case in point: I found these on the FIRST page of a popular auction site, total search time: 1 min. The top strand is DEFINITELY not worth even $10.00!

Consider whether you want your pearls plucked off some warehouse shelf, or tailored to your preferences, with all the care that entails.

A Few Last Minute Pearl Buying Tips ...

  • Choose a higher quality over size.  We recommend that if you're choosing between an Elite Collection 7.0-8.0mm strand and a AA+ quality 9.0-10.0mm necklace, you'll find that the higher luster, smoother surface quality and all around prettier pearls will be the better value.
  • Brands have premiums attached to them that can add as much as 300-400% to the price.  PurePearls.com sources from the same pearl farms as many big name brands without the costly overhead associated with big box store names.
  • The most popular necklace length is the 18-inch, Princess Length.  This necklace will drape over the collar bones, and hang about 1.5-2-inches below the hollow of the throat.
  • The most popular pearl earring sizes range from 6.0-8.0mm – stick within 7.0-8.0mm sizes for adult women, and 6.0-7.0mm sizes for petites and “first pearls” gifts.
