If you want a really unique and special engagement ring, forget the diamond. Go for gems that are rarer than diamonds. There aren’t many of them and they are not easy to find but if it is special you are looking for, there is no better way than to get gems that only a few can get their hands on.
Below are some of these gems, their characteristics, and where they may be found.
Where It Is Found: As stated, it was originally found in Russia. However, stories have it that Georg Fredrick Kunz of Tiffany was so fascinated by the stone that he bought most of the stones mined in Russia. There is no way to verify the story but it is true that there is no known mining camp of Alexandrite in Russia anymore. This is also where the biggest Alexandrite gem was found.
However, several other countries were discovered to have it:
- Sri Lanka (up to 65cts)
- Andrah Pradesh, India (Andhra Pradesh)
- Minas Gerais (Brazil)
- Zimbabwe (small and weak stones)
Characteristics: This is one of the few gems high quality gems that change its colors depending on the light that it absorbs. During the daytime, it should like an emerald. The closer its shade to an emerald, the higher the quality of the gem. During the night time or when the light is warm or weak, it should look like a Ruby. The closer the color to a Ruby, the higher the quality is.
It has three minerals – titanium, iron, and chromium – which contribute to its color changing property.
Fake Vs Real: A Natural Alexdrite has inclusions. It means that when you look inside it, it has black spots. These are deposits of other minerals. If you see bubbles inside, instead of black spots, those are fakes.
If a gem changes to any other color outside of what is written on the characteristics section is not an alexandrite.
If you scratch an Alexandrite on a surface, it will leave a white streak.
However, be careful because synthetic alexandrite have so close a characteristic, even professionals are fooled.
Price: Eleven years ago, an Alexandrite from Brazil with more than 11 carats were sold for more than $380k.

Characteristics: Like other gems, the color of Tanzanite changes depending on the light it absorbs. It is blue under a fluorescent light and violent under incandescent light. However, in its raw form, it is actually brown. It has to go through a specific process for it to turn blue.
Fake Vs Real: Keep in mind that tanzanite is a 3-colored gem. The colors blue and violet must be present.
You should also look for a certification from the Tanzanite Foundation. If there is not certification, don’t buy it.
Price: There are talks that Tanzanite is becoming extinct and the price is starting to skyrocket. The highest grade goes for as much as $800 per carat.

Price: The gem is still undervalued primarily because it is new. You can still get it for $400 per carat. However, remember that as the world gets introduced with the gem, the higher the price will go.
