The growing popularity of lab-grown diamonds is changing how jewelry designers, retailers and manufacturers approach diamond selection and inventory planning. While round diamonds continue to hold a strong position in the market, buyers are increasingly exploring fancy shapes that offer unique aesthetics, larger visual presence and more creative possibilities for jewelry design.
For today’s jewelry businesses, understanding shape preferences is no longer just a design decision; it is also an important inventory strategy. Different diamond shapes appeal to different customer segments, from traditional bridal buyers seeking timeless designs to modern customers looking for customized and distinctive pieces.
In this guide, we’ll explore the most popular lab-grown diamond shapes gaining attention in 2026, why they are trending among designers and buyers and how retailers can make informed decisions when building their diamond collections.
In the lab-grown diamond market, shape plays an important role in customer preferences, jewelry design and inventory planning. While round diamonds represent timeless elegance, fancy shapes like oval, emerald, radiant and pear allow designers to create more personalized and signature collections.
Diamond shape also influences the visual appearance of a jewelry piece. Elongated shapes such as oval and emerald cuts can create a larger face-up appearance compared to round diamonds of similar carat weight, making them attractive to buyers seeking greater visual impact.
For retailers and designers, selecting diamond shapes is not only a creative decision but also an inventory strategy. A balanced collection that includes classic bestsellers and trending fancy shapes helps businesses serve different customer segments and adapt to changing market preferences.
For years, round diamonds have been the preferred choice, especially in bridal jewelry, due to their timeless appeal and exceptional brilliance. However, changing customer tastes and the growth of lab-grown diamonds have increased demand for fancy shapes that offer more individuality and styling versatility.
