A diamond's shape is one of the most important factors in its appearance and personality. While many people focus on carat weight or clarity, the shape is often what creates the first impression. Whether you choose a lab-grown diamond or a natural diamond, the shape determines how the diamond reflects light, appears on the hand, and complements your personal style.
At Twinkle Jewellery, we offer both natural and laboratory-grown diamond Jewellery in a variety of timeless and modern shapes and designs. Understanding the characteristics of each shape can help you make a confident and informed choice.
