For reference, a 2 carat round-cut cubic zirconia (CZ)—the same cut used in our solitaire pendant—typically measures approximately 7.5 to 7.8 millimeters (mm) in diameter.
This size is a popular choice for everyday elegance: it’s noticeable enough to deliver the "sparkle factor" you want (without feeling overly bulky) and perfectly proportioned for a dainty choker. To put it in perspective, it’s slightly larger than a standard pencil eraser (which is about 7mm) but still sleek enough to sit comfortably at the base of your neck—whether you’re wearing it solo or layering with other delicate necklaces.
Since our CZ is precision-cut to maximize brilliance, the 7.5-7.8mm diameter also ensures the stone catches light from every angle (just like a genuine diamond of the same carat weight), making it a stunning focal point for any outfit—from casual tees to cocktail dresses.
If you’re curious about how it will look on you, this size works beautifully for most necklines: it complements V-necks by drawing the eye upward, adds a subtle glow to crewnecks, and pairs seamlessly with scoop necks for a polished, balanced look.
