Pendants are one-of-one by design. We cast one, and this is what you receive as a necklace.

All your questions answered

  • Make in solid Gold or Platinum?

    Yes, absolutely! Special jewellery like this deserves a special metal. We can cast your impression necklaces in most base precious metals, including 9kt to 18kt Yellow, White and Rose Gold, and also Platinum.

    Base metal upgrades such as Gold or Platinum are paid for when you return your wax to us for casting, and are priced according to the current market rates. You can explore some prices here, including base metal upgrades.

    If this is something of interest, you don't need to worry about paying for it now. Our online wax return form will ask you for your preferred base metal.

    Once we receive your wax back, we will confirm the weight and send over a quick payment link to confirm your upgrade. Easy peasy!

  • What are the wax balls for?

    Your wax ball will be lost wax cast into a beautiful solid precious metal. This means that the wax to return to us will be exactly the same once returned, except in a beautiful solid precious metal. It is important that you do not combine the wax balls as they have all been pre-weighed to your chosen casting type.

    The wax balls are not used to take the impression from, they are the literal pendants that you are creating.

    This means that you have the full control and freedom over the size and shape, and the location of your impression.

  • Can you make more than one necklace?

    Your kit includes one pendant and chain prepaid for. However, you absolutely CAN make more than once necklace :) If you'd like to make more, this can all be paid for on our wax return form.

    Let's look at options:

    Use the Other Waxes
    Your kit includes three wax balls. One can be used for your included pendant, and the others can be used to create additional ones. Each additional pendant can be purchase with or without a silver chain. If purchased without, £12.50 is deducted from the price.

    Duplicate the Wax
    If you want more than one copy of the original necklace, we can take a mould of it and duplicate it as many times as you like. Again, this is handled on the online wax return form.

  • Can it be a double-sided impression?

    Yes!! And these look amazing 🤩

    This is made possibly by pushing on the wax ball from both sides at the same time. Be careful not to push too hard, but once complete this style looks so beautiful on a necklace.

  • Is it safe for newborns and children?

    Yes. The wax we use has been independently tested for health and safety. The materials are non-hazardous and non-toxic to humans.

    However, please exercise caution as ever whilst using the product. Please do not ingest it and ensure any young children are supervised whilst using the kit.

  • Can I get more wax?

    Sure, your kit can be refilled on our website here: Refill my Heirloom Kit.

  • How long is the kit valid?

    Each kit comes with a casting voucher for the pendant size that you've paid for (i.e. the mini or micro). All CAST casting vouchers come with a 6-month validity window that covers the full price of casting in silver and protects you against any price fluctuations into the future - even if the casting price increases for your chosen casting type.

    Outside of this 6-month window, you are more than welcome to use your casting voucher, however, a reactivation fee would be automatically applied on our wax return form. This fee steadily increases over time.

  • Engraving, Stones, Plating and more.

    Yes, yes and yes!! Why not make this amazingly special piece of jewellery even more spectacular with some of our extras.

    Available on the wax return form we have the option to add yellow or rose gold plating, precious and semi-precious stones, birthstones, engraving and more!
