What is the difference between star sapphire and Blue sapphire?

Star sapphires and blue sapphires are both types of sapphires, but they differ in appearance and the phenomena they exhibit: Star sapphires and blue sapphires are both types of sapphires, but they differ in appearance and the phenomena they exhibit:

Blue Sapphire:

• Color: Blue sapphire is declared by its saturated blue hue ranging from light to deep blue color. This coloration is as a result of compounds such as iron and titanium the little amounts of which are present.
  
• Appearance: The blue sapphires are usually transparent and do not incorporate any other kinds of red, green, or other color effects apart from the conventional blue sensationally brilliance.
  
• Formation: They are made from aluminum oxide with other traces of different elements that cause the variation of color.
  

  Star Sapphire:

  
  
  
• Color: Natural star sapphires can be blue or other colors but the blue colored is the most popular among them. These can be from light blue to dark blue color very close to the color of the blue sapphires.
  
• Appearance: The chief characteristic of star sapphires is the asterism, which is a minute starry pattern that emerges on the gem when it is cut into a domed and polished straight crown like surface without any facets. This effect is caused by needle like inclusions of rutile silica crystals within the sapphire, which twinkles when it gets possessed with intense light.
  
• Formation: Star sapphires are also made of aluminum oxide the same way other sapphires, but this type of sapphire has rutile inclusions inside which is the cause of star patterns.
  In any case, but blue sapphires are acquired mainly for color and brilliance while star sapphires’ main attraction is the characteristic ‘star’ that is formed from the light reflected by the stone, which sets them quite apart.
