Semi-precious stones

precious stone is a premium decorative material made from large slabs of natural mineral crystals such as fluorite, quartz, and agate. Its distinctive feature is its translucent appearance, which sparkles when illuminated from behind, making each slab a unique, one-of-a-kind work of art.

Siamtak sources semi-precious stones from origins around the world, including Brazil, Uruguay, Madagascar, and South Africa, and offers a Cut to size service to ensure your designs are unique and stand out

What are semi-precious stones?

precious stones are natural minerals that closely resemble gemstones in beauty but are less rare, making them more affordable. When used in decorative applications, crystals with similar colors and patterns are carefully selected and arranged to form a complete sheet. These are then bonded together with clear resin and reinforced with a backing structure to create large, ready-to-install panels.

Due to the unique nature of each mineral crystal, every piece of semi-precious stone has a distinctive pattern that cannot be replicated. Choosing to own this type of stone is therefore like having a one-of-a-kind work of art in your home

How many types of semi-precious stones are there?

The types commonly used for decorative panels are as follows:

Fluorite (calcium fluoride) comes in both green and purple colors. It is highly translucent, making it most suitable for backlit applications.
Rose quartz is a sweet, soft pink crystal that evokes a gentle feeling and is much stronger than fluorite.
Agate, or chalcedony, has clearly defined layered patterns and comes in a variety of shades including gray, brown, and white.

Advantages and disadvantages of semi-precious stones

strength

Translucent and backlit, creating effects that other decorative materials cannot achieve
Each sheet has a unique pattern; it's a one-of-a-kind piece
Cut to size as needed on-site

weakness

Fluorite has a hardness of only 4 on the Mohs scale, which is softer than marble, making it easily scratched and unsuitable for areas with heavy use
Because it involves arranging crystals with resin, high heat and harsh cleaning agents should be avoided
It is a rare material, so its price is higher than that of ordinary natural stone

Where can semi-precious stones be installed?

The selling point of semi-precious stones is their translucency, making them suitable for placement where they can be illuminated from behind, for example:

Backlit wall
Room dividers / partitions
Headboard bar / display counter
Decorative table / Center table
Headboard walls and decorative elements that need to create a focal point

For high-traffic areas like floors or kitchen countertops, we recommend choosing the more durable granite or quartzite instead. Alternatively, consult the Siamtak team about reinforced coatings before making your decision

About Semi-precious stones

What are Semi-Precious Stone Slabs?

Semi-precious stone slabs are decorative surfaces made from pieces of natural gemstones such as agate, rose quartz, amethyst and fluorite.

Unlike marble or granite, these gemstones do not naturally occur in blocks large enough to produce architectural slabs. Individual pieces are therefore selected, cut and carefully arranged before being bonded together with resin to form a larger surface.

The finished slab is then ground and polished to create a smooth surface that reveals the colour, crystal structure and natural variation of each gemstone.

Many semi-precious stones are naturally translucent. When backlit, light passes through the crystals and reveals colours and details that may be less visible under normal lighting, making them particularly effective for feature walls, bar fronts, counters and decorative panels.

Production

The general production process involves:

Selecting natural gemstone pieces for colour and quality.
Cutting or slicing them into suitable pieces.
Arranging the pieces by hand to create the desired pattern.
Bonding them together with resin.
Grinding the completed surface flat.
Polishing the slab to reveal its colour, translucency and crystalline depth.

Because the slabs combine natural gemstone with resin, their technical performance depends on both materials. Application, heat exposure, UV exposure and installation requirements should therefore be confirmed for the specific product.

Application

Semi-precious stone slabs are particularly suited to applications where the material can become a visual feature, including:

Feature walls
Backlit panels
Reception counters
Bar fronts
Vanity areas
Tabletops
Furniture
Decorative architectural elements

Because these slabs combine natural gemstones with resin, suitability for flooring, kitchen worktops, exterior applications, heat exposure and other high-use areas should be confirmed according to the individual product specification.
