The most popular diamond shapes — each with its own character and brilliance
Shape refers to the outline or form of a diamond when viewed from above— round, oval, square, etc. Cut refers to the quality of craftsmanship— how well the facets are proportioned, aligned, and polished.
Every shape can have excellent or poor cut quality. A beautifully cut oval will outshine a poorly cut round every time. When selecting your diamond, consider both the shape that appeals to you aesthetically and the cut grade that ensures maximum sparkle.
Shape is the most personal choice you will make, and it is also a quiet way to buy well. An elongated oval, marquise, or pear can look noticeably larger than a round of the same weight — more presence for the same budget. Our buyers have used that knowledge for over 20 years; now it is yours.
At 2N Diamonds, we offer 10 stunning shapes, each IGI-certified with detailed grading on cut, symmetry, and polish — and each priced up to 45% below traditional retail.

Bow-tie effect visible in elongated shapes
Elongated shapes like Oval, Pear, and Marquise often display a dark bow-tie pattern across their center. This is caused by light leaking through the pavilion rather than reflecting back to your eye.
Some bow-tie is normal and even adds attractive contrast. However, a severe bow-tie creates an obvious dark band that diminishes beauty.
Our advice: When choosing elongated shapes, always view the diamond in person or request video to assess bow-tie severity before purchasing.
For maximum brilliance: Round, Oval, or Radiant
For appearing larger: Marquise, Pear, or Oval
For vintage appeal: Cushion, Asscher, or Emerald
For modern style: Princess or Radiant
For romantic symbolism: Heart or Pear
For sophisticated elegance: Emerald or Asscher
Remember: there's no "best" shape—only the shape that's best for you. Consider your personal style, lifestyle (some shapes are more durable), and what makes your heart sing when you see it sparkle.
