Yes, they are different by several reasons, not just because of the number of zeros added to the right, and to make clear, we will not show contempt neither by one nor the other; we are actually going to explain the difference so you can have the idea of each one.
You must know jewelers draw two lines of distinction between types of jewelry. A line separates the natural jewels of jewelry created in laboratories, while the other separates these two types of jewelry that contain metals or precious gems. What we mean with lab-created is that they produce synthetic gems through a steady process of minerals, heat, and pressure making them more accessible for the buyer.

In order for a piece to be considered fine, it has to be made with certain materials. Fine Jewelry is classified as real gold, platinum, and semi-precious to precious stones and is made to last for generations, on relation to durability and style. Metal is used as base part of fine jewel because it resists corrosion and is not reactive, making jewelry ideal for daily use throughout life. Fine jewelry is made only of solid gold that has to have at least 10K to be considered fine, or platinum, and gemstones must be naturally made. From these stones, among the most expensive and famous you will find diamonds and brilliant-cut that are even more expensive. We also have the emerald and the ruby.
 
Although, today’s fantasy jewelry has created a big impact on humanity because some designers chose to create gorgeous designs on laboratories that look just as the real handmade jewel. Fantasy jewelry emerged in the 1930s as a low-cost and available to all kinds of people, and not intended to be transmitted and bequeathed through the generations; it was intended to be fashionable jewelry for a short period of time.
Of course, they look superficially like gold or platinum, but do not have the corrosion resistance of precious metals as fine jewelry has. Another important difference between fine jewelry and fantasy jewelry is that some fine jewelers make a small collection and each design is rarely seen duplicated on everyone, also each gem has the signature of the designer who created it and that makes them more exclusive and less affordable; on the other hand, fantasy jewelers usually sell for wholesale the same design and its duration is not guaranteed.

To sum up!
So fine jewelry is not cheap, but is worth its price. Since you will have something beautiful for life, and even that will be with the family for generations to come. Fantasy jewelry is a fashion accessory, which plays an important role in enhancing your beauty.
