Prime Style Loose Diamonds


If you are looking for a way to express your personal style and creativity, then loose diamonds are the perfect option for you. Loose diamonds are diamonds that have not been set into any jewelry piece, giving you the freedom to choose the shape, cut, size, color, and clarity of your desired gemstone. Whether you want to create a stunning engagement ring, a dazzling necklace, a pair of elegant earrings, or any other jewelry piece, loose diamonds allow you to customize your design and make it truly unique.

How to Choose the Right Loose Diamonds for Your Jewelry?


Choosing a loose diamond can be a daunting task, especially if you are not familiar with the 4Cs of diamond quality: carat, cut, color, and clarity. To help you make the best decision, we have created a large selection of exquisite loose diamonds, which add a touch of glamour and sophistication to any jewelry piece. Whether you are looking for a classic round brilliant, a romantic heart, or any other shape, we have the perfect loose diamond for you.



Order High-Quality Loose Diamonds Today


Consider a luxurious cushion cut, statement-making emerald cut, historic marquise design, feminine princess shape, or any of the other available cuts. Then shop by carat weight, clarity grade, and price to discover the ideal loose stone. Smart shoppers can often create an even more dazzling piece of jewelry simply by maintaining control over the diamond in the ring, earrings, or bracelet - versus accepting the stone already mounted in a particular piece of jewelry. Browse today and see why PrimeStyle is the ideal destination for diamonds online.
