White Crystalline Marble
Mined from the heart of Lampung, Sumatra, White Crystalline is celebrated for its ethereal translucency and the unique presence of embedded calcite crystals that glitter under ambient light.
White Crystalline Marble: The Radiant Masterpiece of Sumatra Island
Introduction: A Symphony of Light and Stone
In the world of natural stone, few materials possess the ability to transform a space like White Crystalline Marble. Exclusive to PT Gramer Indonesia, this stone is not merely a construction material; it is a geological phenomenon. Mined from the heart of Lampung, Sumatra, White Crystalline is celebrated for its ethereal translucency and the unique presence of embedded calcite crystals that glitter under ambient light.
While many white marbles exist globally, White Crystalline marble stands apart due to its “living” texture. Unlike the flat, milky uniformity of standard limestone, our White Crystalline possesses a complex internal structure formed by intense metamorphic pressure. This process creates a semi-translucent surface that absorbs light before reflecting it, giving floors and walls a waxy, deep glow that feels soft to the eye yet cool to the touch.
The Sole Supplier Advantage
PT Gramer Indonesia is the sole supplier of premium White Crystalline marble.

For architects and developers, this exclusivity is your greatest asset. In an industry flooded with generic, rebranded stones, sourcing White Crystalline ensures your project features a material with a verified provenance. We do not purchase blocks from third-party intermediaries; we control the extraction face. This vertical integration allows us to guarantee:
- Consistency: Uniformity in background color and veining patterns across large-scale commercial orders.
- Authenticity: You are receiving the genuine Lampung metamorphic rock, not a sedimentary imitation.
- Value: By eliminating middlemen, we deliver premium stone directly from the quarry to your project site.
Aesthetic Characteristics
The White Crystalline Marble “Diamond Dust” Effect
The defining feature of White Crystalline marble is in its name. The stone is characterized by macroscopic crystal formations embedded within the white matrix. When polished, these cleavage faces act like tiny mirrors, creating a subtle sparkling effect known in the industry as “flash.”



The Mosaic Collection
For spaces requiring intricate detail, our White Crystalline is available in a stunning array of waterjet and CNC-cut mosaics. These are not just simple squares; they are complex tessellations designed to elevate bathrooms, backsplashes, and feature walls.

Organic Forms
The Wave Mosaic (DK002) features fluid, interlocking curves that soften the rigidity of modern architecture.

Geometric Precision
The Small Brick (DK007) and Herrington (Herringbone) (DK005) offer timeless patterns for classic luxury.

Textural Hybrids
We combine finishes within a single mosaic sheet. For example, our “Polished + Bush Hammered” mosaics create a tactile interplay between smooth and rough, adding depth to white-on-white designs.
