Forever In My Heart ♥ cores for charm beads that fit resin, polymer clay and glass donut beads to make them look perfect on any Biagi, Chamilia or Pandora bracelet. A set for one charm bead consists of a part A and part B. Part A is inserted through your charm bead’s core, the part B placed over the top and flared gently with a 6mm doming punch. You can also use a 6mm ball bearing (included) and lightweight hammer, but the doming punch method is easier, both methods are shown below.

These are the cores we use at Tree of Opals made by the same people for us for the past 4 years. The phrase “Forever In My Heart ♥” is our most requested phrase for engraving, so we know that your clients will feel happy to have this on their charm beads. It’s suitable as a breastfeeding and baby keepsake (breastmilk charm beads, first curl charm beads, placenta and umbilical cord charm beads) but also as a memorial for your clients (cremation ashes charm beads and hair and fur charm beads).

Cores For Charm Beads – Compatability

Perfect for use with our

Please note they are not compatible with slim, super slim, small or large beads due to length of the core. For inserts which are compatible with charms of a different length core please click here for our glue-in charm bead inserts. For advice on making keepsake and memorial jewellery see our blogs here. Don’t forget, we sell bead mould masters too so if you’re able to make your own bead moulds, we’d recommend buying medium, faceted or honeycomb bead masters.

These cores are sold by the set, so for one charm you would just need to purchase one core set. They are much wider than other inserts on the market so they’re ideal for covering up the sanding area on resin charm beads and slight colour run on glass beads.

How to Use Charm Bead Cores

Full blog coming soon with information on sizing lampwork glass beads and attaching the cores. You do not need a machine to fit these (in fact, a grommet press is not recommended and can warp the core). A piece of cloth and a 5mm or 6mm doming punch are all you need, just apply a firm pressure downwards to flare part A over part B. Do not press too hard or you will warp the core and need to use pliers to remove it. We will not replace cores damaged during setting.

We will include 6mm ball bearings with Forever In My Heart Cores, which can be used with a gentle tap of the hammer to flare, be sure to put the bead on a soft cloth before you do it though! Video coming soon.

Pro tip – at Tree of Opals we like to make the client two charm beads with their elements (ashes, hair etc) at the same time. Remove both from the moulds and send the client a photo to check they’re happy and offer them a choice. Let the clients know that you will return the second one free of charge as a spare, and set their favourite with a core. Over half of our clients ask for the second charm to be set, which you may charge £20 for doing. So it’s always worth buying an extra core just in case!

Costing Cores For Charm Beads

Over at Tree of Opals we sell charm beads with hair for around £70 (80EUR/85USD/120CAD/130AUD appx) and sets of them down to around £50, plus occasionally up to 30% off for large family orders, wholesale (funeral homes and crematoria, I used to do 30% off for 10 pieces or more for a breastfeeding group) or black Friday deals etc. The very cheapest I would sell a charm bead for would be £25 as a mystery piece/mystery order addon or for someone who wanted a second charm bead set when you’ve already made two. The profit margin on that is high enough to cover my overheads (websites, payment processing fees, my admin manager, moulds etc) and support my family.

Of course, you can sell charms for £15, and I have seen them that low, but only with silver plated cores. Clients will happily pay extra for a solid silver setting on any piece. We also sell glue-in charm inserts and a set is a little less expensive but they do not fit all the way through the core and will need to be glued in. This will take longer and occasionally they can fall out. These cores provide the most professional option and will set your business above others using glue-ins.

Cores For Charm Beads – Large/Custom orders

If you would like some custom charm beads made our minimum order quantity is 200pcs and your first order will include the cost of designing and making a “die stamp”. You can choose your brand name or business name, or your own special phrase such as “Breastfed with Love” or “Over Rainbow Bridge”. Please order our Branded Charm Bead Core Quote here and give us the details of your business, how many charm beads you sell a month etc.
