Diamonds might be a girl’s best friend, but did you also know they make for great pendants, soap, and decorations?

With this flat diamond-shaped silicone mold, you can create chunky diamonds for a fun and light-hearted style! This mold will leave engraved lines on your diamond, adding that finishing touch to make your diamond really stand out, or letting you create a bright and bold multicolored diamond! The choice is yours!

But don’t think that the engraved lines mean that using this mold is a chore: I’ve designed this mold with ease of use in mind. You will be able to easily create your dazzling diamonds thanks to this molds reusability and durability.


This mold has one cavity. You will create one diamond per use.

A diamond made with this mold has the following dimensions:

  • Size: 41 x 35 mm (1 5/8″ x 1 3/8″)
  • Thickness: 5 mm (3/16″)

This mold is glossy with relief lines. The relief lines are matte. This means that your diamond will be untexturized and will have engraved, pitted lines.


All of my silicone molds are flexible, resistant to tearing, and are durable in use.

Plus, all of my silicone molds can be used with these materials:

  • Resins
  • Epoxy resins
  • Polymer clay
  • Soap
  • Wax
  • Low-temperature melt light metals
  • Plaster
  • Gypsum
  • Concrete

All of my silicone molds have a useful temperature range of -53°C to 232°C / -65°F to 450°F.

Please, don’t hesitate to contact me if you have any questions!
