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

For now, let’s deal with the most frequently asked question first as it deals with the two most popular (and easily confused!) white pearl types: Akoya and Freshwater pearls.
This is probably the most common question I get from customers new to pearls; this quick breakdown between the two pearl types should help make the decision easier for you.
For a more in depth discussion about choosing between saltwater Akoya or Freshwater pearls, I highly recommend reading our full breakdown between the two pearl types, and which pearls you should buy online:Ultimate Guide to Freshwater vs Akoya Pearls
Other major pearl types are black Tahitian pearls, and White or Golden South Sea Pearls – what I call our “Exotic Pearls”. Each pearl type is wonderfully distinctive, with its own traditional pearl colors, size ranges and unique beauty.
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.
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:
DO: Select a vendor that specializes in cultured pearls
DO: Verify a reasonable Return and Exchange policy
DO: Research pearl grading and understand pearl value factors
DON'T: Get stuck on brand names
DON'T: Purchase for price alone
DON'T: Get mislead by inflated pearl grades. AAAA++ is not a real grade!
As a dedicated jewelry professional who's mission in life is to bring beauty and love into the world (it might be cheesy, but I couldn't care less!), I really want for all my clients to understand that there are some vendors out there that really care about their pearl jewelry's legacy, and others that are dedicated to just selling as much as they can without a thought towards the love story that every piece of jewelry given to someone else conveys. So in my view, it’s essential to choose a reputable jeweler that offers quality, transparency, and trust. Whether you're learning how to buy real pearls or comparing pearl sellers, here's a quick guide to the most common buying options:
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. 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 more time acquiring thicker nacre layers in the oyster, and can only be grown one at a time. This combined with the higher risks the farmer undertakes when growing cultured pearls results in higher prices. Smaller Freshwater pearls on the other hand, can grow up to 50 pearls per mussel, contributing to lower prices.
