The 3mm size creates a small but clearly visible heart detail. The faceted K9 Crystal surface reflects the light across its bright red colour, giving the decoration a rich and sparkling appearance.

The classic heart silhouette makes these stones especially suitable for love-inspired designs, but their vivid Siam shade also works beautifully in festive winter and Christmas nail art.

Suitable nail styles

The 3mm K9 Crystal Flatback Hearts work beautifully on short, medium and long nails. Their compact size is suitable for almond, oval, square, coffin, ballerina and stiletto nail shapes.

They are perfect for romantic manicures, Valentine’s Day looks, red crystal nail art, Christmas designs, party nails, heart-themed accents and detailed salon work.

Use a single heart as a delicate accent, line several hearts along the cuticle, or combine them with round rhinestones, pearls, bows and other nail-art decorations.

Colour combinations

Siam red hearts look especially striking on white, milky white, nude, blush pink, soft pink, red, burgundy, black, silver and gold nail bases.

On white or nude nails, the bright red creates a clean, high-contrast romantic accent. On red or burgundy bases, the hearts create a coordinated, luxurious monochrome effect. On black nails, the vivid Siam colour becomes a dramatic statement detail.

Pair them with Crystal, Crystal AB, Siam, Light Siam, Jet, white pearls, gold foil, silver chrome, red glitter and heart-themed decorations.

The special beauty of Siam hearts

The main attraction of these decorations is the combination of an instantly recognisable heart shape and a vivid Siam red colour. The faceted K9 Crystal surface gives the tiny hearts a bright, jewellery-inspired sparkle.

At 3mm, these hearts are small enough for fine detail work but large enough to remain visible on the nail. They can be used to create neat, elegant accents without overwhelming the overall design.

Their vivid red shade makes them versatile across romantic, festive and glamorous manicures.

How to apply and remove

• Prepare the nail and complete the base colour or nail art. Apply a small amount of rhinestone gel, Glue Gel, builder gel, nail glue or another suitable adhesive to the placement area.
• Pick up the 3mm heart with tweezers, a wax pencil or a rhinestone picker. Place it carefully onto the adhesive and adjust its position before curing.
• When using a gel-based adhesive, cure under a UV/LED lamp according to the product instructions. For extra durability, secure the base and outer edges with a small amount of clear gel or Glue Gel.
• Avoid covering the faceted top surface completely, as this may reduce the Light Siam colour depth and sparkling reflection. To remove, carefully file or soften the adhesive before lifting the heart gently. Do not pull it forcefully from the natural nail.

Styling ideas

• Place one 3mm Siam heart on a milky white or nude accent nail for a clean romantic detail.
• Create a Valentine’s Day manicure by pairing the hearts with pink polish, white pearls, bows and Crystal rhinestones.
• Use several hearts along the cuticle line for a small red crystal border.
• Combine the hearts with red glitter, gold foil and green details for a festive Christmas manicure.
• Pair them with black polish, Jet rhinestones and silver chrome for a bold dark-romantic nail design.
• Create a love-letter-inspired manicure by adding the hearts to French tips, handwritten details or tiny bow motifs.
