It is widely believed that the two terms and the distinction they have resulted in has to do with nothing else except marketing. In other words, diamonds, emeralds, rubies and sapphires have been labelled “precious” to sell more by creating the illusion that they’re higher in value than all other gemstones which have been, in turn, labelled “semi-precious.” Even though some semi-precious stones are higher in rarity than precious gemstones, until this day, the following four gemstones continue to be labelled precious:
Beauty, value and sturdiness make diamonds every woman’s dream. Although diamonds are hardly rare, their value only increases by time, thanks to their popularity and, certainly, the harsh conditions under which they’re formed.
Although rubies are known for being bright red, their color can range from pale rose to dark red, and sometimes even purple. Just as diamonds are formed from carbon, rubies are formed from corundum which is transparent in color, but whose traces of chromium result in the red color of rubies.
Also formed from corundum with a variety of other mineral traces that result in its blue color. According to geology.com, any corundum that is not red (i.e. ruby), blue (i.e. sapphire) or colorless (i.e. white sapphire) is known as “fancy sapphire.”
A variety of beryl, emeralds are made green by traces of either chromium, the same mineral that makes rubies red or, sometimes, vanadium. According to geology.com, if the beryl gemstone is not rich in color, it’s not an emerald but simply “green beryl.”
Labels aside, the fact remains that precious gemstones are precious, otherwise they wouldn’t have continued to be labelled as such. They are one of the few things that people, regardless of their differences, can hardly disagree about. Whether for their ornamental or monetary value, precious gemstones continue to fascinate jewelry lovers of all tastes and backgrounds.
