The largest, cleanest diamond isn't always the most beautiful one on the hand. The way a diamond is cut, shaped, and set can make it appear larger, shine more brilliantly, and discreetly mask its natural characteristics. Often, these choices influence a diamond's beauty far more than a higher carat weight or clarity grade ever could.

At Royal Asscher, technical precision and 172 years of family craftsmanship work together. Knowing how a shape can hide inclusions, how a cut maximizes face-up size, and how proportion shapes visual impact is at the heart of our bespoke diamond service. Our goal is simple: help you choose a stone that looks generously expansive, sparkles with life, and is worthy of becoming an heirloom.

Start With What Matters Most to You

Every great diamond decision begins with a question: what do you care about most?

Some clients want the internal character of the stone kept discreet. Others want the visual presence of a larger diamond. Many chase sparkle above all else. Naming your priority first makes everything that follows, whether it is shape, cut, and setting , becomes a deliberate choice rather than a compromise.

A few terms worth knowing:

• Inclusion — A natural mark formed as the diamond grew, such as a tiny crystal, feather, or pinpoint. Most are microscopic, but their size and position can affect both the clarity grade and, occasionally, what you can see.
• Face-up size — How large a diamond looks from above once it's set. This depends on shape and proportion, not carat weight alone. Two stones of identical weight can look noticeably different in size.
• Brilliance — The white light a diamond reflects back to your eye. High brilliance reads as bright, lively, and full of sparkle, and it depends on precise cutting and symmetry.
• Proportions — The exact measurements and angles of a diamond's facets: depth, table size, crown height, pavilion angle. They decide how light travels inside the stone, and therefore how bright and how large it appears. Balanced proportions make a diamond look larger and livelier; poor ones make it look smaller or dull.

Want to Hide Inclusions? Choose Brilliant Cuts

If concealing inclusions is your priority, a brilliant-faceted diamond is widely considered the best diamond cut to hide inclusions. Its facets scatter light in every direction, and that busy, sparkling movement makes small internal marks far harder to spot.

The Royal Asscher Brilliant takes this further with 74 precisely engineered facets, which is more than the traditional brilliant, heightening scintillation and optical complexity. The result is greater light performance that camouflages minor inclusions while keeping the stone bright, white, and alive.

Top Brilliant-Cut Shapes for Masking Inclusions

The following diamond shapes are among the best diamond cuts for hiding inclusions due to their dynamic light return:

• Royal Asscher Brilliant – The most efficient light performer, offering maximum sparkle and strong concealment of minor inclusions.
  
• Royal Asscher Cushion – Softened corners and brilliant faceting create a romantic glow while diffusing internal characteristics.

Love Clean Geometry? Understand Step Cuts First

For clients drawn to architectural elegance, step cuts offer a timeless sophistication. But they behave very differently from brilliant cuts. Instead of scattering light, they create a clear, "hall-of-mirrors" effect, which means inclusions show more, not less.

That openness makes clarity selection critical. Those broad, mirror-like facets act as windows into the stone. For an eye-clean result, we generally advise a clarity grade of VS2 or higher, though every stone deserves individual assessment. A clarity grade that disappears in a brilliant shape can become visible in a step cut.

Maximize Face-Up Size Through Proportion, Not Just Carat

Choosing the diamond cut that maximizes face-up size isn't about buying more weight. It's about precision engineering.

Proportions describe the exact relationships between a stone's table, total depth, crown height, and pavilion depth. Together they decide how well a diamond reflects light and how large it reads from above. A heavy stone can still look small if its proportions are off, for example, either burying weight beneath the surface (too deep) or looking glassy and lifeless (too shallow). The sweet spot is disciplined balance, where carat weight becomes visible presence.

Three numbers on a grading report tell most of the story:

• Diameter (mm) — For round diamonds, the average measured width. This directly reflects face-up size: a larger millimeter measurement means a larger visible surface, whatever the carat weight.
• Depth percentage — Total depth divided by average diameter. A slightly lower depth generally spreads the face-up view wider for the same weight. Round brilliants commonly fall around 58–62%; dip much below ~58% and you risk light leakage and lost brilliance.
• Table percentage — The table's width relative to the diameter. A moderately larger table can make a diamond look bigger, but an oversized table sacrifices fire by shrinking the crown.

The finest stones balance a generous spread with disciplined light performance — so size never comes at the expense of sparkle.

Let the Setting Do Some of the Work

The diamond sets the foundation, but the setting shapes how the stone finally appears on the hand. The right metal framework can visually expand a diamond's presence and quietly hide small inclusions, which sometimes lets you choose a slightly lower clarity grade with no loss of beauty.

Settings that maximize size or hide inclusions:

• Halo — A ring of smaller diamonds around the center stone enlarges the overall diameter, creating the impression of a much bigger diamond.
• Micro-pavé — Tiny diamonds along the band add continuous sparkle that draws the eye away from any minor marks in the center stone.
• Bezel or partial-bezel — A slim metal rim encircles the stone, hiding inclusions near the girdle while protecting the edges.
• Strategic prong placement — Thoughtfully positioned prongs can cover perimeter inclusions while still letting light flood in.

Certification, and the Judgment Behind It

Independent certification is your assurance that a diamond's beauty is backed by verified quality. A report from a respected laboratory such as GIA confirms that cut, clarity, color, and carat weight have been evaluated objectively, giving you a confident basis for comparison.

But a certificate only tells part of the story. In 172 years, the Asscher family has learned that a strong report doesn't always mean a beautiful stone, so we sometimes decline diamonds that grade well but don't perform to our eye. Beauty is judged in the hand, not only on paper.

That judgment is woven into the bespoke service at Royal Asscher. You'll receive clear guidance on the 4Cs of diamond quality, the reassurance of our lifetime craftsmanship standards, and a diamond chosen to become a confident, enduring heirloom.
