Pearl certified appraised jewelry is that pearl jewelry which comes with a certificate of appraisal.
This is vital for high quality expensive pearls and pearl jewelry and if you are buying online it is a must.
Check that the seller has a returns policy so you can return the piece if you find it is not as described or not as the appraisal certificate states. It is a good idea to get an additional independent appraisal and check that it matches the one that comes with the pearl.
If the pearl comes set in jewelry check the setting minutely. If there is a string of peals the certificate should include all the pearls or there should be a certificate for each pearl (unlikely however). Check that the pearls are round and have good lustre.
There are different types of pearls, Freshwater, Akoya, Tahitian Black etc. Ensure you know what you want and what you are buying matches what you want.
It is a good idea to have an idea in mind of what you want and how much you wish to pay. Including any precious metal that may come with the pearls as part of the jewelry.
Do a lot of browsing both online and at professional gemological jewelers in your town or city. Try and get to see many pearls. Feel them and roll them in your hand and check out the lustre and colors available.
The more you are familiar with pearls the better informed you will be when it comes to making a choice.
And any pearl or pearl jewelry should have a proper certificate accompanying it. If not them look elsewhere.
Keeping the above in mind will go a long way to ensuring that you are satisfied with your eventual purchase of pearl certified appraised jewelry
