Difference Between Them before Buying Your Pearl Jewellery
Want to know the difference between South Sea pearls and freshwater pearls for a necklace?
In case you need a pearl necklace for an elegant day-to-day look, a gift, or wedding, freshwater pearls are a great option in terms of beauty and price, and South Sea pearls are known for their rarity, bigger size and luxury, so it all comes down to the choice that will fit your personal preferences and budget.
The Gemological Institute of America (GIA) considers the South Sea pearls to be among the biggest pearls in the world. Usually, these pearls have sizes from 8mm to 20 mm, while freshwater pearls can be found in various sizes, shapes, and colors which make them one of the most versatile jewels.
Two Beautiful Pearls, Two Different Stories
These two pearls might seem very alike at first sight.
However, there is a lot more in their stories than just an identical appearance and the opportunity to make a beautiful elegant necklace.
Consider the South Sea pearls to be the statement pearl that you wear only on your most important occasions, whereas the freshwater pearls are the classic pearl that you just can't stop wearing.

South Sea pearls include:
