See our Returns & Refunds Policy for full details.

Do you offer branded packaging?

Yes. Every order is designed to feel special with the House of Honcho branded unboxing experience. Perfect for proposals, gifts and luxury keepsakes.

Are your diamonds certified?

Yes. Our lab-grown diamonds are IGI or GIA certified depending on the stone selected. Natural diamonds are also available on request and can be sourced with certification for peace of mind.

Do you offer natural diamonds?

Yes. While we specialise in lab-grown diamonds, we can source natural diamonds for custom orders. Message us with your preferred shape, size, budget and design idea.

Are your rings real gold?

Yes. Our jewellery is solid gold or platinum. Our rings come in 18k gold or platinum, and our tennis bracelet is solid 14k gold. We do not sell gold plated or cheap costume jewellery.

Do you offer custom orders?

Yes. Custom orders are one of our specialties. Send us your dream ring, wedding band, tennis bracelet, necklace or jewellery idea and we’ll help bring it to life.

Can you make custom engagement rings?

Yes. We can create custom engagement rings in your chosen diamond shape, carat size, metal type and setting style. DM us your design inspiration and we’ll guide you through the options.

Do you make wedding rings?

Yes. We can source different carat sizes depending on your budget and design. Bigger, sparklier certified diamonds are available for custom orders.

What is the difference between 14k gold, 18k gold and platinum?

18k gold has a richer gold content and a premium feel, and is what we use for our rings. 14k gold is a little harder-wearing, which suits an everyday bracelet. Platinum is a naturally white, very durable luxury option.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are real diamonds with the same chemical and visual properties as mined diamonds. They offer incredible sparkle and value.

Can I see the diamond certificate?

Old-world cut. New-world nerve.

Before machines and laser maps, diamonds were cut by hand and by candlelight. The result was the old mine cut: a softly squared stone with a high crown, a small table and big, chunky facets that throw slow, flashing light instead of a busy sparkle. It glows like a lantern rather than glittering like a disco ball, which is exactly why collectors chase antique ones.

The Radiator brings that warmth back with a full 3 carats of lab-grown diamond, cut in the old mine style and set alone so nothing distracts from it. Wear it and people lean in. They always ask.

Our rings come in US and Australian sizes. Not sure of yours? Have a ring that fits measured by a local jeweller, or contact us and we'll help you find the right fit.

Getting the right size first time means your ring arrives ready to wear. Use one of the two methods below, then find your size in the chart. If you fall between two sizes, choose the larger one.

Quick tip: Australian sizes use letters (the same system as the UK). US sizes use numbers. Every ring on our store shows both, for example US 6 / AU L½.

Method 1: Measure a ring that already fits

Choose a ring that fits the finger you're buying for.
Lay it flat on a ruler with millimetre markings.
Measure straight across the inside of the ring, from inside edge to inside edge. Don't include the metal.
Find that number in the Inside diameter column below.

Method 2: Measure your finger with paper

Cut a thin strip of paper about 1 cm wide.
Wrap it around the base of your finger. It should be snug but still slide over your knuckle.
Mark where the paper overlaps with a pen.
Lay the strip flat on a ruler and measure from the end to your mark, in millimetres.
Find that number in the Circumference column below.

Ring size chart: Australia and US

US size	AU / UK size	Inside diameter (mm)	Circumference (mm)
4	H½	14.9	46.8
4.5	I½	15.3	48.0
5	J½	15.7	49.3
5.5	K½	16.1	50.6
6	L½	16.5	51.9
6.5	M½	16.9	53.1
7	N½	17.3	54.4
7.5	O½	17.7	55.7
8	P½	18.1	57.0
8.5	Q½	18.5	58.3
9	R½	18.9	59.5
9.5	S½	19.4	60.8
10	T½	19.8	62.1

Most of our rings come in US 4 to 9. Some pieces also come in 9.5 and 10. Measurements are a guide and may vary slightly.

Tips for an accurate fit

Measure at the end of the day. Fingers are slightly bigger in the evening and when you're warm.
Measure 2 or 3 times to make sure you get the same number.
Wide bands (over 6 mm) fit tighter. Go up half a size.
Your dominant hand is usually a little larger.
Buying a surprise? Borrow a ring they already wear on the right finger and use Method 1.
Still unsure? Any local jeweller can size your finger for free in a few minutes. You can also contact us and we'll help.
