Drilled Setting vs Prong Setting; Which Should You Choose?

Diamonds sparkle because of cut and light, but how a Diamond is mounted changes what you see, how it wears, and how it must be cared for. Two common approaches, drilled single drill or double drill) and prong (claw) settings, offer distinct appearances, strengths and trade‑offs.

Why does the mounting matter?

A setting does more than hold a stone. It controls exposure to light, comfort against the skin, everyday security, cleaning and repair needs; and even long‑term value. Choosing the right method is both a practical decision and a design choice.

Drilled setting

“Drilled” refers to a precise micro-hole created in the Diamond, either a single hole from the pavilion, or two holes running from the crown facet to the pavilion near the girdle on either side. This allows a fine post, tube, or wire to pass through, securing the Diamond while keeping visible metal to a minimum. 

Typical uses:

Drilled diamonds are typically used in floating and minimal  jewellery such as necklaces, bracelets and pendants, as well as in briolette and bead-style stringing, low-profile earrings and suspension settings and specialised invisible or design-driven mounts.

Advantages:

• Low profile and exceptionally clean silhouette; less metal visible, more ‘floating’ look.
• Comfortable for earrings and skin‑close pieces.
• Very secure when done correctly: the internal post/tube anchors the stone.
• Excellent for small melee stones where a minimal metal look is desired.

 

Considerations:

• Permanent alteration: Drilling removes Diamond material and creates a lasting change to the stone.
• Not suitable for every Diamond; clarity, cut and crystal structure affect whether drilling is safe.
• Requires expert lapidary work; poor drilling can cause fractures or stress.
• Cleaning can be trickier (holes can trap dirt).

 

Prong (claw) setting

Metal prongs (usually four or six) grip the diamond at the girdle and lift it above the shank or mount, exposing most of the stone.

Typical uses:

Centre stones in engagement rings and solitaires, larger Diamonds where maximum brilliance is desired.

Advantages:

• Maximises light exposure and therefore brilliance, prongs show more of the stone.
• Versatile: works with many shapes and sizes; prongs can be tailored (V‑prongs for pears/marquises).
• Easier to inspect, clean and re‑set; the Diamond remains unaltered.
• Familiar, classic aesthetic that highlights the stone.

Considerations:

• Prongs can snag on clothing or hair and need regular checks and occasional re‑tipping.
• More exposed profile, a higher setting can be vulnerable to knocks and chipping if bumped.
• Requires periodic maintenance to ensure long‑term security.

Quick comparison:

• Appearance: Drilled = ultra‑clean and low‑profile. Prong = lifted, showy and brilliant.
• Light performance: Prong typically maximises brilliance; drilled mounts can be very attractive but may alter pavilion function depending on the design.
• Security: Both can be secure when expertly made; prongs rely on metal integrity, drilled mounts rely on the drilled anchor.
• Reversibility: Prong is more reversible (stone stays intact). Drilling is permanent.
• Best for: floating and minimal  jewellery. Prong; solitaires and larger centre stones that benefit from light exposure.

 

How to choose the right option for you:

• For studs and low‑profile earrings: drilled Diamonds are a smart choice for comfort and a seamless look.
• For a solitaire engagement ring or a display‑focused centre stone: prong settings show the Diamond to best effect.
• If resale or future re‑setting is important: avoid drilling, a non‑altered stone keeps more flexibility and market appeal.
• If you lead an active life: consider protective alternatives (bezel or flush) — prongs can catch; drilled mounts are low but must be expertly made.
• Consult an expert: not every stone can or should be drilled. An experienced lapidary and jeweller will assess the Diamond’s structure and recommend the safest approach.

You don't have to choose just one. Modern pieces often combine techniques: a prong‑set centre diamond framed by drilled melee, or drilled accents in a predominantly prong‑mounted design. Thoughtful mixing gives you the visual balance of maximum brilliance and a clean, contemporary finish.

A matter of personal expression

Ultimately, the best choice is the one that matches how you want a piece to look, feel and live with you. Whether you prefer the slender, almost‑invisible profile of a drilled setting or the classic lift and sparkle of prongs, both approaches offer beautiful outcomes when selected and executed with care.
