10 Stunning Diamond Shapes to Choose From
Choosing diamond shapes is one of the most personal decisions in the buying process. Each cut interacts with light differently, produces a unique face-up size, and carries its own character. At Noble Jewelers, we carry nine distinct shapes to match every style and preference.

Cushion Cut
Cushion cut diamonds blend a rounded square or rectangular shape with larger facets that enhance the stone's natural fire. Their soft, pillow-like outline has a romantic, vintage feel and works beautifully in both solitaire and halo settings.

Asscher Cut
The asscher is a square step-cut diamond with deeply trimmed corners and a distinctive "hall of mirrors" optical effect. Like the emerald cut, it highlights clarity and rewards buyers who appreciate architectural precision over conventional sparkle.

Round Brilliant
The round brilliant cut features 58 precisely angled facets engineered to maximize light return. It is the world's most popular diamond shape, accounting for approximately 75% of all diamonds sold globally. If brilliance and fire are your top priorities, round cut diamond is the benchmark cut.

Oval Diamond
The oval diamond cut offers the brilliance of a round diamond in an elongated shape that flatters the finger and can appear larger than its carat weight suggests. Its symmetrical form makes it versatile across ring styles, from classic to contemporary.

Emerald Cut
The emerald cut diamond uses a step-cut faceting style that creates long, open flashes of light rather than sparkle. Its rectangular shape and large, flat table emphasize clarity and color, making stone quality highly visible. Best suited for buyers who prefer understated elegance over maximum brilliance.

Marquise Cut
The marquise cut features two pointed ends and a curved body, maximizing carat weight while creating one of the largest face-up appearances of any shape. Its elongated profile makes it ideal for those who want a bold, distinctive look.

Heart
The ultimate symbol of love, the heart cut diamond is among the most romantic of the diamond shapes.

Radiant Cut
The radiant cut is a trimmed-corner rectangle with 70 facets that deliver powerful brilliance similar to a round but in a more geometric form. Its versatility pairs naturally with both rounded and square accent stones.

Princess Cut
Princess cut diamonds feature a square shape with sharp corners and 76 facets. They deliver striking brilliance and typically princess cut diamond price from 20–30% less per carat than a comparable round diamond, making them an excellent choice for buyers who want maximum size and sparkle within a budget.

Pear Shape
The pear, or teardrop, cut combines a rounded bottom with a single point at the top. It produces exceptional brilliance and creates a visually elongating effect when worn as a ring. A strong choice for pendants and drop earrings as well.
The 4Cs Choose Brilliance with Confidence
Every diamond’s value is determined by diamond 4Cs universal grading criteria. Understanding these four factors allows you to balance quality and value with confidence.
- Carat measures size and weight.
- Cut governs how effectively the stone handles light — it is the most impactful factor in a diamond’s visual performance.
- Diamond color grade is on a D-to-Z scale; Noble Jewelers carries D through J, spanning colorless to near-colorless.
- Diamond clarity measures internal and surface characteristics; our inventory ranges from FL (flawless) to SI2 (slight inclusions visible under 10× magnification).
Which Diamond Wins? Natural vs. Lab-Grown
Natural diamonds form over one to three billion years under extreme pressure more than 100 miles beneath Earth’s surface. Lab diamond Aruba diamonds replicate that process in six to ten weeks using HPHT or CVD technology. Both types are graded identically on the 4Cs and are chemically, physically, and optically identical. Noble Jewelers carries both options, allowing you to choose based on origin preference, budget, or both.
