Product Identification Manual

Why This Guide Matters

Travertine door handles often look similar at first glance.
The difference only becomes clear after months—or years—of daily use.

This guide is not about brands or prices.
It explains how to identify a truly well-made travertine handle, based on material origin, internal structure, craftsmanship, and long-term performance.

Section 1｜Stone Origin & Internal Structure

Is the stone structure natural and stable?

NO – Common inferior stone

  • Pores are chaotic and irregular

  • Visible crystal impurities and deep fractures

  • Color appears muddy or uneven

  • Stone feels soft and brittle

YES – ABC-STONE standard

  • Selected Italian Roman-origin travertine

  • Fine, naturally distributed pores

  • Clean internal structure with controlled density

  • Warm, original stone color

Section 2｜Pore Quality

Are the pores naturally formed, not artificially repaired?

NO – Artificially treated pores

  • Large pores filled with glue or cement

  • Surface looks “too perfect”

  • Pores appear blocked or flat

YES – Natural pore preservation

  • Small, open pores remain visible

  • No excessive filling or surface coating

  • Texture remains breathable and authentic


Section 3｜Edge Craftsmanship & Radius

Are the edges rounded for long-term hand comfort?

NO – Mechanical or rushed finishing

  • Sharp chamfered edges

  • Inconsistent curves

  • Feels rigid or uncomfortable in hand

YES – ABC-STONE edge standard

  • Carefully refined 68° edge radius

  • Gradual, multi-step hand polishing

  • Smooth transition without sharp breaks


Section 4｜Surface Finish & Aging

Does the surface age gracefully over time?

NO – Surface deterioration

  • Color darkens unevenly

  • Becomes patchy or stained

  • Texture loses depth

YES – Natural patina development

  • Surface develops soft patina

  • Color becomes warmer and deeper

  • Texture gains character over time

Section 5｜Structural Consistency

Is the handle shape consistent and structurally sound?

NO – Inconsistent shaping

  • Uneven thickness

  • Visible asymmetry

  • Weak structural points

YES – Balanced stone geometry

  • Controlled proportions

  • Consistent thickness

  • Designed for daily use, not display only
