The colour of rubies is sometimes said to appear as though there is a flame eternally burning within the stone, symbolising everlasting love.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"background-color:#c03232\"><div class=\"wp-block-group__inner-container\">\n<h4 class=\"has-very-light-gray-color has-text-color has-text-align-center\">2. <strong>The ruby was originally named \u201cratnaraj\u201d.&nbsp;<\/strong><\/h4>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-1024x682.jpg\" alt=\"necklace\" class=\"wp-image-24541\" width=\"570\" height=\"379\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-1024x682.jpg 1024w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-300x200.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-768x512.jpg 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-1110x740.jpg 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-930x620.jpg 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-750x500.jpg 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-510x340.jpg 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-360x240.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280-120x80.jpg 120w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625724_1280.jpg 1280w\" sizes=\"(max-width: 570px) 100vw, 570px\" \/><\/figure><\/div>\n\n\n\n<p>The first ruby was discovered in India, so the stone was named in the native language. The Sanskrit \u201cratnaraj\u201d means \u201cking of precious stones\u201d. Although in modern times, the diamond is often seen as being the superior gemstone, the ruby certainly deserves this royal title for its deep, enticing colour. \u201cRuby\u201d comes from the Latin \u201crubeus\u201d, meaning \u201cred\u201d.<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"background-color:#c03232\"><div class=\"wp-block-group__inner-container\">\n<h4 class=\"has-very-light-gray-color has-text-color has-text-align-center\">3. <strong>They are of the corundum family.&nbsp;<\/strong><\/h4>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/joshua-fuller-p8w7krXVY1k-unsplash-1024x683.jpg\" alt=\"10 Interesting Facts About Rubies\" class=\"wp-image-24508\" width=\"570\" height=\"378\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/joshua-fuller-p8w7krXVY1k-unsplash-300x200.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/joshua-fuller-p8w7krXVY1k-unsplash-360x240.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/joshua-fuller-p8w7krXVY1k-unsplash-120x80.jpg 120w\" sizes=\"(max-width: 570px) 100vw, 570px\" \/><\/figure><\/div>\n\n\n\n<p>Both rubies and sapphires are members of the corundum family. Corundum stones are suitable for jewellery as they are dense, compact and do not have gemstone cleavage. This means that the stones do not have pre-existing weaknesses and are therefore less likely to crack.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"background-color:#c03232\"><div class=\"wp-block-group__inner-container\">\n<h4 class=\"has-very-light-gray-color has-text-color has-text-align-center\">4. <strong>Their colour comes from chromium.<\/strong><\/h4>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-1024x661.jpg\" alt=\"ring\" class=\"wp-image-24547\" width=\"574\" height=\"370\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-1024x661.jpg 1024w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-300x194.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-768x496.jpg 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-1536x992.jpg 1536w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-2048x1323.jpg 2048w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-1110x717.jpg 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-930x601.jpg 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-750x484.jpg 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-510x329.jpg 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-360x232.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/ruby-1-120x77.jpg 120w\" sizes=\"(max-width: 574px) 100vw, 574px\" \/><\/figure><\/div>\n\n\n\n<p>Pure corundum is colourless and made up of aluminium and oxygen. In order to gain colour, it must come into contact with small amounts of chromium. The chromium replaces some of the aluminium in the stone\u2019s structure and it becomes a red ruby. Strangely, chromium also gives emeralds a green colour.<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"background-color:#c03232\"><div class=\"wp-block-group__inner-container\">\n<h4 class=\"has-very-light-gray-color has-text-color has-text-align-center\">5. <strong>There are different types of rubies.&nbsp;<\/strong><\/h4>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625720_1920-1024x683.jpg\" alt=\"tear drop ruby necklace\" class=\"wp-image-24787\" width=\"574\" height=\"380\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625720_1920-300x200.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625720_1920-120x80.jpg 120w\" sizes=\"(max-width: 574px) 100vw, 574px\" \/><\/figure><\/div>\n\n\n\n<p>As rubies can be found in many parts of the world, they are not all going to be the same. Burmese rubies are recognised as being the highest quality and have a deep red colour. African rubies tend to be a purplish, dark red colour. Thai rubies are a deep shade of red as they have traces of iron in them. Star rubies are a natural phenomenon. They can be identified from the six-prong star that is visible on the surface. Light reflects off of tiny fibres of rutile to create this striking effect.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"background-color:#c03232\"><div class=\"wp-block-group__inner-container\">\n<h4 class=\"has-very-light-gray-color has-text-color has-text-align-center\">6. <strong>Rubies have been used in the foundations of buildings.&nbsp;<\/strong><\/h4>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625727_1920-1024x683.jpg\" alt=\"flower ruby necklace\" class=\"wp-image-24796\" width=\"574\" height=\"379\"\/><\/figure><\/div>\n\n\n\n<p>Although rubies are the second strongest gemstone, they were not placed in the foundations of buildings for structural purposes. As the stone is believed to bring good luck and fortune, some have placed a ruby in the ground before the foundations of their house have been laid. It is hoped that the good luck from the stone will have a positive influence over the household.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-group has-background\" style=\"background-color:#c03232\"><div class=\"wp-block-group__inner-container\">\n<h4 class=\"has-very-light-gray-color has-text-color has-text-align-center\">7. <strong>The Liberty Bell Ruby is the largest mined ruby in the world.<\/strong><\/h4>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-1024x683.jpg\" alt=\"10 Interesting Facts About Rubies\" class=\"wp-image-24799\" width=\"570\" height=\"379\" srcset=\"https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-1024x683.jpg 1024w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-300x200.jpg 300w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-768x512.jpg 768w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-1536x1024.jpg 1536w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-1110x740.jpg 1110w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-930x620.jpg 930w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-750x500.jpg 750w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-510x340.jpg 510w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-360x240.jpg 360w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920-120x80.jpg 120w, https:\/\/www.firstclasswatches.co.uk\/blog\/wp-content\/uploads\/2021\/03\/jewelry-625725_1920.jpg 1920w\" sizes=\"(max-width: 570px) 100vw, 570px\" \/><\/figure><\/div>\n\n\n\n<p>The ruby was discovered in east Africa in the 1950s and weighs 4 pounds and is 8500 carats. <a href=\"https:\/\/www.worldatlas.com\/articles\/a-list-of-the-most-valuable-and-word-famous-rubies.html\">The Liberty Bell ruby<\/a> was sculpted into the shape of the Liberty Bell, a symbol of American independence.

It sits in the centre of the Imperial State Crown of the United Kingdom, above the Cullinan II diamond. Although commonly referred to as a ruby, this impressive stone is actually an irregular cabochon red spinel. Prior to 1783 when spinels were first chemically differentiated from rubies, all red gemstones were called rubies. Rubies are corundum stones, whereas spinels are made up of magnesium, iron, oxygen and chromium.
