Which ruby gemstone is the best
Yves Lemay | Jul 24, 20
Ancient Hindus valued ruby more than any other gems and named it accordingly "ratnaraj" or "king of precious stones." Its red color purity defines the top-quality rubies, which do not have any violet, orange or brownish overtones. Rubies will have microscopic inclusions; these are not detrimental if they do not detract from the gem's brilliance and are not eye visible.

Though emerald is undoubtedly precious, it is certainly not among the new precious stones. Before the discovery of emerald in Colombia in the sixteenth century, the green variety of corundum was called oriental emerald. The only source of real emerald known to early Mediterranean cultures was the fabled Cleopatra’s mines in the Sinai Desert.

What is zircon stone
The beautiful, historically significant gemstone, zircon, has, unfortunately, in recent years, become tarnished by its name-only similarity to cheap, synthetic cubic zirconia. Of course, the two are totally distinct in their chemistry, optical properties, and origins.

Is turquoise green or blue
Chemically, turquoise is a hydrated copper/aluminum phosphate, of aggregate, cryptocrystalline structure. There is only one known deposit in Virginia, where turquoise is found in transparent to translucent visible crystals. Specimens from that locality are rare and bring a hefty price from collectors.

Where tourmaline is found
Tourmalines are gems with an incomparable variety of colors. According to an old Egyptian legend, the tourmaline, on its long journey up from the center of the Earth, passed over a rainbow. In doing so, it assumed all the colors of the rainbow. And that is why it is still referred to as the 'gemstone of the rainbow' today.

Where topaz is found
The term "precious" topaz was originally used to distinguish yellow and orangish topaz from other gems such as some citrines and smoky quartzes, which had erroneously been referred to in the past as "Maderia topaz' and "smoky topaz." Topaz of any type is an excellent jewelry stone, and it is historically one of the most valuable gemstones.
