  • Materials: Crystal
  • Made to order

Seller's description

Elevate your space with our stunning, hand-crafted K9 crystal diamonds.

K9 crystal, also known as K9 glass or optical crown glass, is indeed known for its high-quality optical properties. Here are some key points about K9 crystal:

High refractive index: As you mentioned, K9 crystal has a relatively high refractive index compared to many other types of glass or crystal. This property contributes to its ability to bend light more effectively.
Increased "shimmer": The high refractive index does result in more light dispersion, which creates the "shimmer" or sparkle effect. This makes K9 crystal popular for decorative objects, chandeliers, and optical components.

Optical clarity: K9 crystal is known for its excellent optical clarity, which makes it suitable for use in various optical applications.

Durability: While not as hard as true diamond, K9 crystal is reasonably durable for a glass material.

Available in two impressive sizes, these masterpieces blend optical brilliance with artistic craftsmanship.

Sizes and Specifications:

Standard: 300mm (11.81 inches) across, weighing 40 lbs (18.14 kg)
Medium: 400mm (15.75 inches) across, weighing 92.6 lbs (42 kg)
Large: 600mm (23.622 inches) across, weighing 200 lbs (90.72 kg)
Massive: 800mm 31.50 inches) across, weighing 460 lbs (208.65 kg)

Key Features:

High refractive index for exceptional brilliance and sparkle
Superior light transmission and clarity
Precision hand-crafted for unmatched quality
Durable optical glass, more resistant to scratches than regular glass

Light Interaction:

Creates mesmerizing rainbow effects and light dispersion
Transforms under various light sources (natural, LED, incandescent)

Applications:
Indoor:

Luxurious home decor centerpiece
High-end retail display
Hotel and restaurant statement piece
Museum or art gallery installation
Photography and film prop
Corporate lobby or office showpiece

Outdoor (limited exposure):

Garden sculpture
Event and wedding decor
Temporary public art installation

Note: Not recommended for prolonged outdoor use or in direct sunlight.

Care Instructions:

Clean with a soft, lint-free cloth
Use mild soap and lukewarm water for deeper cleaning
Avoid abrasive cleaners or rough materials
Handle with care, preferably with clean, dry hands or gloves
Store in a padded container when not on display
Avoid rapid temperature changes

Customization:
Custom sizes and shapes available upon request. Please contact us for more information.

Handling Note:
Due to the significant weight, professional installation is recommended, especially for the 600-800mm versions. The large size (200 lbs) and massive size (460 lbs) require multiple people for safe handling and positioning.

Experience the unparalleled beauty of our K9 crystal diamonds – where science meets art in a dazzling display of light and precision.

Cost-effective: K9 crystal offers many desirable optical properties at a lower cost compared to some other high-quality optical materials.

It's worth noting that while K9 crystal is marketed as "crystal" due to its optical properties, it is technically a type of glass rather than a true crystalline material like natural quartz crystal.
