Natural Diamond Spray

What This Product Is

Natural diamond spray delivers a natural (mined) monocrystalline diamond suspension in a spray applicator for metered, even cloth charging. Natural diamond's tough, blocky crystals are preferred by some procedures, and the spray form makes recharging quick and consistent while reducing waste.

Intended Use in Metallography

Used for intermediate and fine polishing, selected when:

  • A procedure specifies natural diamond
  • Fast, even, metered cloth recharging is wanted
  • A tough, blocky crystal suits the material

Typical Applications

Commonly used for:

  • General and specialty metals and alloys
  • Applications where natural diamond is the established abrasive
  • Routine polishing where quick, even recharging helps

Beyond metallography, natural diamond spray is also used in:

  • Petrography of hard minerals
  • Ceramics, glass, and optics
  • Tool, die, and mold finishing

When This Product Is NOT Ideal

  • When synthetic monocrystalline or polycrystalline diamond is specified or more economical
  • When a paste or suspension better suits the process

Where This Fits in the Preparation Process

  • After grinding
  • Before an oxide final polish, when required

What is the difference between natural and synthetic diamond spray?

Natural diamond is mined and tends to be tough and blocky; synthetic monocrystalline is manufactured and very consistent. Both are supplied in the same convenient spray form; the choice depends on procedure and material preference.

Water-soluble or oil-soluble?

Water-soluble suits most general work; oil-soluble is chosen for moisture-sensitive materials. Both are offered — see the product options.

Why choose a spray applicator?

It applies a metered, even dose of diamond to the cloth, making recharging fast and consistent and reducing waste versus hand-charging.

Can natural diamond spray be used outside metallography?

Yes. It polishes hard materials across petrography, ceramics, glass and optics, and tool and die finishing. Some labs prefer natural diamond's tough crystals; the spray form adds convenient, even application.
