DIY jewellery box in plaster: trinket boxes, ring holders and organisers to give as gifts

TL;DR: A DIY jewellery box in plaster takes just an afternoon: pour Aqua Resin into a silicone mould, demould after 30 minutes and decorate after 24 hours of drying. Lidded trinket boxes, ring holders and organisers come out with a smooth porcelain-effect finish, perfect to keep or to give as Christmas gifts.

Introduction

A DIY jewellery box solves a very real problem: rings left by the sink, odd earrings in the drawer, necklaces tangled at the bottom of your bag. DIY jewellery boxes made from cardboard or reclaimed wood don't last long or need tools; porcelain-effect plaster ones, on the other hand, are elegant, sturdy and can be made at home with just a mould and a set of scales. In this guide you'll find 7 plaster jewellery box ideas, the method for fitting the base and lid without surprises, decorating techniques and tips for protecting the inside when the jewellery box lives in the bathroom.

Key points

• Ratio: 100 g of Aqua Resin for every 30 g of cold water; demould after 30 minutes, fully dry within 24 hours.
• Material: Aqua Resin is not an epoxy resin: it is a premium alpha plaster, non-toxic and water-based.
• Fit: the base and lid are demoulded together, dried apart and fine-tuned with a light sanding if needed.
• Bathroom: for a jewellery box exposed to damp, brushed-on Aqua Shield protects the inside but leaves a glossy finish.

What you need

• Aqua Resin: the white alpha plaster that gives a smooth porcelain-effect finish
• A silicone jewellery box mould: no release agent needed
• Scales, container and spatula for an accurate mix
• Fine sandpaper to fine-tune the edges where the lid closes
• Colours and finishes (optional): Aqua Pigment, Aqua Metal, gold or silver leaf

The method is also suitable for children aged 5 and over with adult supervision: there are no solvents, fumes or catalysts, and tools clean up with plain water. Gloves are not required.

7 DIY jewellery box ideas

1. Round trinket box with lid

The timeless classic: the Jewellery Box mould with lid is 10.4 cm in diameter and 13.7 cm tall overall, lid included. The base and lid are poured at the same time and, once dry, your DIY jewellery box is ready for earrings, wedding rings and small pendants. In pure white it looks like porcelain; with a brush of gold on the knob it becomes a display piece.

2. Carousel jewellery box

A little bedside merry-go-round: the Carousel Jewellery Box mould measures 10 x 11 cm and has a shape that appeals to grown-ups and little girls alike. In pastel shades, powder pink or sky blue, it makes a sweet gift for a young girl or for anyone who loves objects with a vintage touch.

3. Organiser tray for rings and bracelets

If you're looking for a DIY jewellery organiser for your dressing table, the jewellery organiser tray (10.5 x 18.9 cm, 1.9 cm thick) keeps rings, bracelets and watch neatly separated on a single surface. It is flat and stable: ideal inside a drawer too.

4. Heart ring dish

The quickest DIY ring holder: a small heart-shaped dish to leave by the sink or on the bedside table, where you take off your rings before washing your hands or going to bed. It demoulds in 30 minutes and, with a gold rim, also makes a lovely favour.

5. Angel wings

A soft hollow for rings and little treasures: the Angel Wings mould measures 12.8 × 14.8 cm and is 7 cm deep. In white with silver leaf on the wing tips, it is a delicate idea for a new baby, a First Communion or a loved one.

6. Christmas bell

The Bell mould comes in two pieces, base and lid: it is the little gift box to put under the tree, with a piece of jewellery, a note or a chocolate inside. After the holidays it stays on as a jewellery box.

7. Christmas gnome

A fun jewellery box for lovers of Nordic style: the gnome with its pointed hat keeps rings and earrings safe and decorates the shelf all winter long.

If you need a dish for keys and coins rather than jewellery, you'll find shapes and techniques in the guide to DIY trays and catch-all dishes.

How to fit the base and lid

The tricky part of any jewellery box with a lid is the fit. Here's the method we use in our workshop:

1. Prepare a single mix for both pieces. Pour the powder into the cold water, 100 g of Aqua Resin for every 30 g of water, and stir slowly until you have a smooth cream. With a single mix, the base and lid have the same colour and the same finish.
2. Pour and tap. Fill both cavities to the brim and tap the mould on the work surface to bring the air bubbles to the top.
3. Demould after 30 minutes. Flex the silicone gently, starting from the edges, without levering on the thin parts.
4. Dry for 24 hours, with the pieces apart. Don't close the box straight away: moisture would be trapped inside.
5. Test the fit. If the lid doesn't slide down smoothly, lightly sand the rim with fine sandpaper, brush off the dust with a dry brush and try again.

Pro tip: mark with a pencil the point where the lid and base line up best: if you decorate the two pieces aligned, the design flows from one to the other and the box looks as if it came straight from a ceramics studio.

How to personalise your jewellery box

• Pastel shades: with Aqua Pigment in the mix you get powder pink, sage or powder blue; a few drops are enough for a delicate colour.
• Gold details: Aqua Metal is applied by brush only, never in the mix. Perfect for the knob on the lid or the outline of the Carousel.
• Gold and silver leaf: a few flakes on the rim or on the wing tips are enough for a precious effect.
• Marbled effect: add the pigment to the mix and stir just twice, so the veining stays visible.

Protecting the inside from damp

If the jewellery box is going to sit in the bathroom, next to the sink, it's worth protecting it. Brush Aqua Shield onto the dry piece, focusing on the inside where you put down wet rings; alternatively, you can dip the piece in a bath of Aqua Shield. Aqua Shield is transparent, but it leaves a glossy finish and may slightly alter the colour: if you want to keep the matt porcelain look on the outside, treat only the inside. For an organiser that is always exposed to damp, you can also use Aqua Shield directly in the mix instead of water, 50 g for every 100 g of Aqua Resin, demoulding after at least 1 hour.

A handmade jewellery box as a Christmas gift

As the holidays approach, the DIY jewellery box is one of the projects we recommend most, for a simple reason: it is a useful, personal gift that never goes out of style. You can choose the recipient's favourite colour, write an initial on the lid with Aqua Metal and tuck a small piece of jewellery inside. The Christmas bell in particular is already gift packaging: no wrapping paper needed. To round off your list of presents to prepare in advance, you'll find more ideas in the guide to DIY Christmas gifts.

Common mistakes

• Using two different mixes for the base and lid. The colour may vary from one piece to the other: prepare a single mix.
• Closing the box before 24 hours. Moisture stays inside and the lid may stick or leave marks.
• Sanding too much. One light pass on the rim is enough: remove too much material and the lid will wobble.
• Putting Aqua Metal in the mix. It should only be brushed onto the dry piece.
• Forgetting protection in the bathroom. Without Aqua Shield, the inside absorbs moisture from wet rings.

FAQ

How do you make a DIY plaster jewellery box?

Pour Aqua Resin, 100 g of powder for every 30 g of cold water, into a silicone jewellery box mould. After 30 minutes, demould the base and lid, leave them to dry for 24 hours and then decorate them.

Does a plaster jewellery box wear out with use?

No: once dry, an Aqua Resin jewellery box stands up to everyday use. Just treat it like a porcelain object, without dropping it or submerging it in water.

Can I keep the jewellery box in the bathroom?

Yes, if you protect it. Brush Aqua Shield onto the dry piece, especially on the inside: it protects against damp, but leaves a glossy finish and may slightly alter the colour.

The lid doesn't close properly: what should I do?

Wait until both pieces are completely dry, then lightly sand the rim with fine sandpaper and try again. Often all it takes is removing a small burr left over from pouring.

Is a DIY jewellery box a good Christmas present?

Yes: it is useful, personal and can be made in advance. You can choose the colours to suit the person receiving it and tuck a small piece of jewellery or a note inside.
