Special Feature: Fluorescence: Manganocalcite is a fluorescent mineral.

Under ultraviolet (UV) light: The stone emits a strong pink to reddish glow

This effect is caused by the presence of manganese in the crystal structure, which activates light emission when exposed to UV radiation .

This creates a dual character:

• Daylight: soft, calm pink

• UV light: vivid glowing color

Metal Pairings

• Rose gold: enhances softness and warmth

• Yellow gold: adds richness

• Silver: creates a fresh, clean contrast

• Polished finishes: support the smooth surface

Recommended Settings

This natural gemstone cabochon performs best in:

• Bezel settings for protection

• Minimal designs

• Earrings and pendants

• Concept pieces incorporating UV interaction

Ideal for jewelry where the fluorescence becomes part of the design concept

A Different Standard for Cabochons

Most manganocalcite on the market is:

• Weak in color

• Full of grey impurities

• Structurally inconsistent

• Poorly polished

We reverse that process. Each cabochon is selected under a defined gemstone quality system — only the finest 5% qualifies.

This ensures a high-quality cabochon with:

• Clear and attractive pink coloration

• Smooth, uniform structure

• Strong fluorescent response

The result is a cabochon for jewelry making with both visual and functional uniqueness.

The Gemrock Standard for Manganocalcite

Not all manganocalcite is suitable for jewelry.

Before cutting, we evaluate:

• Color quality (clean pink tones)

• Structural integrity

• Surface quality and polish response

• Fluorescence intensity

Only a small fraction meets these criteria

In-House Precision Cutting

Every precision-cut cabochon is shaped and polished in our own workshop.

We control:

• Dome symmetry and proportions

• Edge precision for a secure setting

• Surface polish to enhance pattern clarity

No uneven domes. No dull finishes. No mass-production shortcuts.

About Manganocalcite

Manganocalcite is a manganese-rich variety of calcite, where manganese replaces part of the calcium in the crystal structure.

This gives the stone:

• Its characteristic pink coloration

• Its ability to fluoresce under UV light

The intensity of both color and fluorescence depends on the manganese content.

Manganocalcite is valued for:

• Its soft, calming appearance

• Its unique fluorescent behavior

• Its distinct position among decorative stones

Durability & Wearability

Manganocalcite is a relatively soft stone.

This means:

• It is sensitive to impact and abrasion

• It should be used in protective settings

• It is best suited for lighter jewelry applications

Ideal for earrings, pendants, and carefully designed rings.

Care & Cleaning

Proper care will preserve the appearance of your manganocalcite cabochon.

How to care for manganocalcite jewelry:

• Avoid strong impact or abrasion

• Do not use ultrasonic or steam cleaners

• Clean with a soft cloth and mild water

• Avoid harsh chemicals

• Store separately to prevent scratching

Gentle handling is essential due to its softness.

Natural Material & Authenticity

This is a natural gemstone cabochon, untreated and selected under strict material standards.

• Lower-grade material often shows:

• Weak or uneven color

• Poor polish

• Limited fluorescence

Our selection ensures only visually strong and fluorescent material is used.
