Buy top quality stones in any gem types
Don't buy small stones (under 1 carat)
Buy well cut stones
Stick to the more popular gems

At the moment the stones that are rising in value include: Top Quality Sapphire, Green Tsavorite Garnet, Orange Spessartine Garnet, Chrome Tourmaline, red and hot pink Tourmaline, Tanzanite, Emeralds as well as fancy coloured diamonds and good Mogok rubies.

Obviously the more reasonably you can purchase the gem, the more profit to be made. It is a good idea to purchase your gemstones direct from the miners or gemcutters, not jewelers. Check your stones are genuine and have no treatments. Do not expect to buy and then sell in a few weeks or even months, be patient and watch your market.

Reasons to invest in Gemstones
The world's supply of natural gemstones is limited as to what already exists. No more is being made. As it takes millions of years to create a gemstone naturally Many of the large producing mines of the world are already mined out, or nearly so. Although there are new discoveries, even these are limited supplies and will eventually be depleted. As the worlds population increases, so will the demand. Once it was only the elite that owned gemstones, but now everyone wishes to own( and can afford) natural gemstones. As we move into the future, I can only see natural gemstones going up in value.
