What Are Specialty Diamonds? A Comprehensive Guide to Their Unique Characteristics

Specialty diamonds are diamonds that fall outside the standard selection due to their rare characteristics. These may include unusual cuts, vivid colours, or custom shapes. Unlike mass-produced stones, specialty diamonds are selected for their uniqueness and artistic value. They’re perfect for clients who want something more than the conventional. From fancy coloured stones to hand-selected custom cuts, specialty diamonds turn fine jewellery into personal statements.

Rare Diamond Cuts

The shape of a diamond plays a major role in how it reflects light and how it stands out. Rare diamond cuts include:

  • Asscher Cut

    A vintage-inspired step-cut with bold facets.

  • Trillion Cut

    A triangular cut offering brilliance and modern flair.

  • Rose Cut

    A flat-bottomed diamond with a dome-shaped crown, popular in antique settings.

  • Cushion Modified Brilliant

    A unique twist on the cushion cut with extra sparkle.

These cuts are not commonly available at chain retailers and are typically sourced through custom or boutique jewellers like Diamovida.

Fancy Coloured Diamonds

Colour adds a whole new dimension to a diamond. Fancy coloured diamonds naturally occur in hues like yellow, pink, blue, and green. Their rarity makes them highly valuable.

  • Natural Fancy Colours

    Formed over millions of years with trace elements like nitrogen or boron.

  • Treated Coloured Diamonds

    Enhanced through heat or irradiation—more affordable but less rare.

Whether you want a champagne diamond for everyday wear or a vivid pink stone for an engagement ring, coloured diamonds redefine what’s possible in fine jewellery.

Custom Diamond Shapes and Designs

Specialty diamonds also include those that are custom-cut into specific shapes based on client requests. Examples include:

  • Heart-shaped diamonds

  • Initial or symbolic shapes

  • Asymmetrical or geometric freeform cuts

These are ideal for clients looking to create deeply personal, bespoke pieces. At Diamovida, we work closely with clients to design and source diamonds that fit their vision.

Why Choose a Specialty Diamond?

A specialty diamond offers more than just beauty—it tells a story. Here’s why more buyers are making the switch:
