About

Gemstones are formed in the earth, therefore they have something mystical and enigmatic about them.
For thousands of years collectors have been fascinated by the radiance of a ruby seen in daylight or candlelight,
by the deep blue light reflected from a sapphirine or the intense green of an emerald.

What is it that makes a gemstone so special? The answer is simple: its rarity and desirability.
The rarer and more coveted something is, the higher its price will be, whether it is jewellery,
worn as an expression of sentiment, or as a mere store of value.

Especially in times of economic uncertainty gemstones can be a lasting long term investment.
“Natural gem auctions“ (NGA) offers a transparent and reliable occasion
to purchase gemstones by auction for a reasonable price.
