Blue Nile: Pear Shaped Rings
You want a teardrop-shaped diamond. Because pears are not uniformly standardized, we explore why one brand makes selecting a beautiful stone objectively less dangerous.
Quick Verdict
Buying a pear shape online without seeing high-definition video is essentially gambling. Pear shaped diamonds notoriously suffer from the "bow-tie effect" — a dark, light-blocking shadow cast across the center width of the stone. Blue Nile easily wins this category because their unrestricted 360-degree high-definition video allows you to spin the pear and visibly verify if a crippling bow-tie shadow exists. Blue Nile has excellent inventory, but "blind buying" a pear shape relying solely on certificates is highly discouraged.

The Danger of the Bow-Tie
Round diamonds hide their flaws through immense, algorithmic light return. Pear shapes are "fancy cuts." As light travels from the rounded bottom towards the sharp point, the angles of the facets get confused. This frequently creates a harsh black shadow across the very center of the stone that looks exactly like a man's bow-tie.
Almost all pear shapes have some minor shadowing, but a severe bow-tie ruins the diamond. Unfortunately, "bow-tie severity" is NOT listed on a GIA certificate. You cannot read a piece of paper to avoid it; you have to see it with your own eyes.
James Allen's Technological Ace
This is where the James Allen business model acts as a lifeline. They physically capture a 360-degree, 40x magnification video of every diamond in their database.
You can spin a pear shape on the Blue Nile website and watch how light reacts across the center facets. If you see a thick, distracting black bow-tie shadow, you skip the diamond. Blue Nile often relies on stock photos or standard certificates for cheaper fancy cuts, making it a severe gamble. You simply cannot safely buy a pear diamond without visual confirmation.

The Final Decision
If you buy a round diamond, math can protect you. If you buy a pear shape, your eyes must protect you. James Allen's requirement that every diamond is filmed in ultra-high resolution prevents you from making a devastating mistake. Navigating past a thick, black bow-tie shadow is the single most important aspect of buying a pear shape, making James Allen the clear victor.
