Sapphire is the best-known blue gemstone (though it also occurs in many other colors). Sapphire's blue color can range from light-blue to deep-blue. Since sapphire is a gem-quality form of corundum, it is incredibly hard and durable, with a hardness of 9 on the Mohs scale.

It is also considered to be one of the most precious of all gems available today. Some blue sapphires are known to exhibit phenomenal characteristics such as asterism (star) or color shift abilities. Today, blue sapphire from Sri Lanka (Ceylon) is considered most desirable, but previously, finds from Kashmir and Mogok, Burma, were known to be the finest quality.

Blue sapphire from Cambodia (Pailin) was also known to be of distinctive purity. Many even consider Pailin sapphire to be close in quality to Kashmir, Burmese and Sri Lankan (Ceylonese) sapphire. Sapphire can also be found with phenomenal traits, such as rare color change sapphire, as well as remarkable chatoyant star sapphire. Blue star sapphire is highly sought-after and especially valuable by collectors and jewelers alike. Sapphire is also one of September's birthstones.

Rainbow Moonstone Gemstones

Moonstone is the best-known variety of orthoclase potassium feldspar, but 'rainbow moonstone' is technically not a true moonstone at all. Rainbow moonstone is a trade name for a special variety of labradorite, which is plagioclase feldspar that exhibits a bluish adularescence similar to the potassium feldspar moonstone.

However, most consider both gem types to be one and the same for simplicity's sake. The name 'moonstone' is owed to moonstone's bluish-white shimmering effect that resembles the moon shining in the night sky. The phenomenon is known as adularescence and is a result of moonstone's unique structural pattern.

Though most moonstone exhibits a bluish-white sheen, many other colors can be seen through its adularescence. Moonstone that exhibits the optical phenomenaof chatoyancy is rare, but not unheard of. Chatoyant moonstone is known in the gem trade as star moonstone.

Blue Spinel

Natural Blue Spinel Gemstones
Blue Spinel Gemstones

For many centuries, blue and red spinel was mistaken for blue sapphire and red ruby. Spinel has very similar gemological properties to sapphire and ruby, which are both forms of corundum. Like corundum, spinel can also occur in a wide variety of colors.

Some spinel colors are considered rarer and more valuable than others. In general, fine red spinel is considered to be the most valuable, followed by rare blue spinel. Cobalt-blue is the most desired shade of blue spinel. Like diamond, spinel is singly refractive, resulting in very pure color.

The best blue spinel should have medium to medium dark color, similar to fine blue sapphire. Unlike sapphire, blue spinel is typically never treated in any way. Spinel is just slightly softer than sapphire, but it is still considered very hard and durable. Therefore it is perfectly suitable for any type of jewelry application.

Diamond is the hardest known natural material on earth, rating 10 on the Mohs scale of mineral hardness. Its name comes from the Greek word 'adamas', meaning invincible. Diamond is composed of pure carbon, the same material that makes up graphite, a very common material used in the production of pencil lead and various other industries.

Blue diamond is typically irradiated to obtain its color, though some very rare stones may be completely natural and untreated. Most blue diamond will exhibit a secondary greenish hue. Blue diamond is prized for its rarity, exceptional hardness, high refractive index and high dispersion rating - the ability to split white light into its component colors.
