A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum.
The word ruby comes from rubber, Latin for red. The color of a ruby is due to the element chromium. Rubies have a hardness of 9.0 on the Mohs scale of mineral hardness. Historically, rubies have been mined in Thailand as well as in Afghanistan, Australia, Brazil, Colombia, India, Namibia, Japan, and Scotland. As July's birthstone, rubies symbolize freedom, divinity, royalty, wisdom, and spirituality. Rubies are also said to inspire love, courage, confidence, and creativity.
Pink sapphires belong to the corundum family of minerals. They contain traces of iron, titanium, magnesium, copper and chromium that help determine its color. The higher the chromium content, the deeper the pink hue. In some cases, it’s difficult to distinguish a pink sapphire from a ruby. Only a gemologist will be able to make this distinction. The leading producer of natural pink sapphires is Madagascar. Pink sapphires were considered incredibly rare prior to the 1990s when the Madagascar mines were discovered. Pink sapphire mines are also present in Myanmar, Sri Lanka and East Africa.
A pink sapphire’s place of origin doesn’t usually impact its price or value. Many cultures and people believe pink sapphires symbolize trust, loyalty and sincerity. They’re also believed to carry good fortune and intense love.The increase in popularity of pink sapphires has sparked the number of pink sapphire engagement rings on the market. Many brides prefer the unique, feminine color to a white diamond or blue sapphire. For weddings with a blush or baby pink color scheme, pink sapphires are the perfect compliment.
Diamonds are a form of the element carbon with a crystal structure. Diamond's great hardness relative to other materials has been known since antiquity, and is the source of its name derived from the ancient Greek ἀδάμας that means "unbreakable".
Diamonds are the hardest natural substance on earth and rate a 10 on the Mohs Hardness Scale. Diamond is also known as April's birthstone. They are thought to be first recognized and mined in India many centuries ago.
Four characteristics, known informally as the "Four Cs", are now commonly used as the basic descriptors of diamonds: Carat, Clarity, Color and Cut.
This system was developed by GIA (Gemological Institute of America), one of the major gemological associations internationally recognized to evaluate diamond characteristics.
The carat weight measures the mass of a diamond and the clarity is a measure of internal defects of a diamond called inclusions.
GIA’s D-to-Z diamond color-grading system measures the degree of colorlessness: the finest quality as per color grading is totally colorless, which is graded as D color diamond across the globe, meaning it is absolutely free from any color. Last, the cut of a diamond describes the quality of workmanship and the angles to which a diamond is cut.
