RUBY
Coloured rubies are among the safest gemstone investments. They are seen by collectors to agree their value and market demand better than diamonds, particularly every bit they become rarer.

At the same time, similar examples from other sources, such every bit Madagascar, Mozambique and Tanzania, are also quickly increasing in price. Brilliant carmine examples are the most valuable, known to dealers equally "pigeon's claret". Rubies oft have inclusions, so colour is a more important factor in the value of a stone than clarity.
EMERALD
Though the market place for emeralds has seen some disruption in the last couple of decades, the stone has traditionally been considered an investment. In ancient Egypt, they were used past merchants to hedge their wealth against disasters. Greenish emerald is a favourite among collectors, in particular big-sized stones from Republic of colombia and Brazil. Even so, information technology is becoming increasingly more than difficult to find loftier-quality emeralds, making them as safe an investment as you can find in the gemstone market.

SAPPHIRE
While blue sapphire is the second most pop coloured stone for investors, after carmine, other colours are fast growing in popularity. Sapphires are found in all colours of the rainbow, from greenish and orange to purple and even salmon pinkish, in the case of Padparadscha sapphires. Globally, a medium- to dark tone called Imperial Blue with lots of saturation is best for investors, though this can depend on the location of your market. More often than not speaking, greater colour saturation and a deeper tone will push button up the price, although a darker stone will invariably exist cheaper than a lighter coloured one.

TANZANITE
Mined in only i location roofing just half-dozen square kilometres in Tanzania, tanzanite can just go up in value. The owner of this land, in the foothills of Kilimanjaro, is attempting to control the marketplace, similar to the way De Beers sets the value of diamonds. If it succeeds, which is probable, this will pb to a pregnant ascent in prices, which currently showtime from U.s.$ane,000 upwards to U.s.$five,000 per carat. With more than interest coming from the vast Asian market, led past People's republic of china, supplies are nether pressure level, and could be depleted quickly.

PARAIBA TOURMALINE

Blue-green examples are worth twice equally much every bit pure blue stones, as are other shades of green. Investors tip mid-range tones for best returns.
ALEXANDRITE
Another exceedingly rare and investment-worthy rock is alexandrite, a color-changing crystal that has been outperforming the stock markets in recent years. Otherwise a chrysoberyl, itself a precious stone, what marks alexandrite out is how its chemical limerick reacts to different light sources, turning from blueish-greenish in daylight to a red-purple at nighttime. Over the last one-half-decade, collectors have been seeing double-digit almanac returns on this mineral investment. And with fourth dimension running out on reserves of an already exotically priced stone, their investment is bound to bound further upwards in value as remaining stocks are depleted. Prices vary according to individual stone, with gems of infrequent quality reaching up to U.s.$100,000 per carat.
SPINEL
Hardly anyone seemed interested in investing in spinels only five years ago, just after some excellent price growth, and benefitting from an elevated contour fuelled by the popularity of candy-coloured designer jewellery collections, they are now considered worthy investment gems. Though pure spinel is colourless, impurities are responsible for its rainbow of colours.
