When it comes to adding a touch of the earthy, warm and natural tones of brown to your jewelry collection, there are several unique gemstones that can do the job. One of the most popular options is the cognac diamond, a type of diamond that has been treated to achieve a rich brown color, similar to that of the drink cognac. Another option is the chocolate diamond, which as the name suggests, is a diamond that naturally occurs in various shades of brown from light to dark. They are less common than white diamonds and can add a touch of rarity to your collection.
Other options for those who are looking for something truly unique and rare, include the brown sapphire, a variety of corundum that comes in a range of brown hues, and the brown spinel, a mineral that is beautiful, durable and valued for its range of brown colors. Another gemstone that can provide a great earthy touch is the Smoky Quartz and Smoky Topaz, which ranges from light to dark brown. Dravite, a variety of tourmaline known for its brown hues is also a great option that is less commonly known.
