Always remember that natural pearls are quite rare and are expensive as compared to the cultured pearls
. It is better to go for a natural one for your engagement ring, because generally engagements are held only once in a life time so it should be given more emphasis to get everything at its best for that event and the most important item on engagement is undoubtedly an engagement ring so it should be one which is really unique and breathtaking. A beautiful pearl embedded in a gold or platinum band will be a center of attraction on the occasion.
