Diamond Cuts: Which Cut Gets You the Best Resale Value?

Every diamond is unique and factors like clarity, cut and colour set each one apart. The internal conditions of the Earth’s surface determine how a diamond forms, giving each its own character. 

In this article, let us explore the ‘cut’ aspect of the diamond in detail, its types, its effect on the resale value and some investment tips to help buyers and sellers make informed, confident decisions.

What Are Diamond Cuts?

Diamonds form over millions of years, deep within the Earth’s crust. Extreme pressure and heat transform carbon into rough stones, later polished by gemcutters. While 'shape' and 'cut' are often used interchangeably, they are not the same.

The cut of a diamond refers to the proportions, symmetry and angles that determine how well the diamond reflects light. On the other hand, the shape of a diamond refers to the external appearance.

The rough diamonds are cut by the gemcutters to enhance their beauty. The cut quality affects brilliance, sparkle and overall appearance. The common types of cuts include round, princess, emerald, oval, marquise, cushion and heart cuts.

Types of Diamond Cuts and Their Characteristics

• Round Brilliant Cut
  Round brilliant is the most popular and highly sold cut. Its brilliance and symmetry make it timeless. Because of its strong demand, it commands the highest resale value.

• Princess Cut
  Princess cut is a modern, square-shaped cut with sharp edges and excellent light reflection. It has a slightly lower resale value compared to a round cut but is a good alternative.

• Cushion Cut
  The cushion cut follows a vintage style with rounded edges. They are named after their pillow-like shape. Often seen in engagement rings for its soft, romantic appeal.  

• Emerald Cut
  Emerald cut is a rectangular, step-cut design that highlights clarity over sparkle. Ideal for high-quality diamonds, offering elegance at a lower price point.

• Oval Cut
  Oval-cut diamonds are highly durable, elongated and stylish, enhancing perceived size. Their resale value varies depending on the proportions and symmetry.

• Pear cut
  The pear-cut diamond is a teardrop-shaped cut known for its elegance. It is  difficult to craft, making it less common than other diamond cuts. 

• Marquise cut
  The Marquise Cut has an elongated shape with pointed edges. Its long and narrow form creates the illusion of greater size, making it one of the timeless diamond shapes. 

• Heart cut
  Heart Cut diamonds are a true showcase of love. Their dazzling appearance makes them perfect for expressing affection and celebrating classic romance.

How Diamond Cut Affects Price and Resale Value

The symmetry of a diamond’s cut determines its brilliance and overall appearance. Well-cut diamonds reflect maximum light, appear more vibrant and command higher prices, while poorly cut diamonds look dull and have lower market value.

When selling diamonds or diamond jewellery, buyers and appraisers focus primarily on brilliance. A well-cut diamond retains its appeal and value over time, whereas poorly cut diamonds may struggle to achieve a good resale price. Round Brilliant cuts generally command the highest resale value, while fancy shapes often cater to niche markets, affecting liquidity. The cut grade (Excellent, Very Good or Good) also significantly influences investment potential.
