Carat weight doesn’t always equal how “big” a diamond looks. Oval, pear, and radiant shapes often appear larger than round diamonds of the same weight. During your appointment, we’ll show you how shape affects presence on the hand.
The setting dramatically changes the look of a shape. Solitaire, halo, hidden halo, bezel, and three-stone settings each enhance sparkle and proportion differently. We’ll help you compare combinations that match your aesthetic.
Some shapes hold up better for active lifestyles. If you’re hands-on daily, rounded shapes or protective settings may be ideal. We’ll walk through durability, wearability, and long-term care.
You don’t need an exact number—just a range. This allows us to curate diamonds that give you the best beauty and value without guesswork.
White, yellow, and rose gold all frame shapes differently. We’ll help you try different metals to see what complements your diamond and your personal style.
