Pink diamonds, similar to white diamonds, range from Flawless up to Heavily Included. To date, the Pink Star is the world’s only pink diamond that is totally flawless.

Red Diamond

Red diamond is one type of diamond with similar mineral properties as those of colorless diamonds that boasts of red color. Red diamonds are often dubbed as the rarest color and most expensive diamonds in the world, even more so than blue or even pink diamonds. The source of the color of these diamonds are still the topic of debate yet the gemological community often attribute the colors to the gliding atoms in the diamond’s structure as this goes through intense pressure during the formation process.

Emerald

Emerald is one type of gemstone, a variety of mineral beryl, whose green color is due to chromium’s trace amounts and vanadium at times. The hardness of beryl on the Mohs scale is at 7.5 to 8. Many emeralds are highly included, which means that their toughness or breakage resistance is categorized as poor in general.

Taaffeite

Taaffeite is a type of mineral whose name was taken after the person who discovered it, Richard Taaffe, who was able to find the very first sample, a polished and cut gem, in October 1945 in Dublin, Ireland. This is why this is the sole gemstone first identified from faceted stone. Many pieces of the gem had been incorrectly identified as spinel before Taaffe’s discovery. This was known in just a few samples for several years after and this remains to be among the rarest gemstone minerals of the world.
