The Collection List

Starting a gem collection feels daunting when there are thousands of gemstones in the world. But in actual fact, there is only a handful of gems that Jewellers will collect. Other kinds mostly remain as mineral specimens that Geologists are more interested in.

 

If you're starting your gem journey, this would be a useful guide for you.

If we categorize them in the most traditional way, Precious Gems vs Semi-Precious Gems.

Diamond 

 

Most of the time colourless, which is what people commonly use in engagement rings. 

Ruby 

Sapphire

Emerald

Red, Blue and Green respectively. These are most commonly seen in all retail shops. They can range from dirt cheap to extremely unaffordable.

Only these four gemstones are considered Precious Gems, everything else would be a Semi-Precious Gem. This is mainly due to historical reasons. However today, there are many semi-precious gemstones that are even rarer and more expensive than some of these precious gems, like Paraiba Tourmalines or Alexandrites.
