How much does custom jewellery cost? Each ENBOM DIAMONDS piece is quoted for its metal, stone and making. Two real quotes are USD 950 for a 1-carat lab-grown diamond pendant and USD 3,150 for a 2.76-carat tennis bracelet. The quote is free, and the USD 200 design payment counts towards the total price.
What did two real custom pieces cost?
These are two quotes ENBOM DIAMONDS gave for specific designs. They show what those pieces cost with the details recorded at the time. They are useful starting points, but neither price can be transferred to a different design without checking its stone, metal and setting.
| Piece | What was quoted | Quoted price |
|---|---|---|
| Pendant | A 1-carat lab-grown pear-cut diamond, set in platinum and 18ct yellow gold | USD 950 |
| Tennis bracelet | Bezel-set stones, 2.76 carats in total | USD 3,150 |
The pendant quote answers a fairly specific question: what did one 1-carat lab-grown diamond pendant cost? The platinum and yellow gold are part of that answer. Change either metal, the pear shape or the way the stone is held, and the quote needs to be worked out again.
The bracelet quote gives the total weight of the stones, 2.76 carats. Total weight says nothing by itself about how many stones share it or how large each one is, and both change the sourcing and the setting work. That is why USD 3,150 is the price of that bracelet, not of every tennis bracelet.
What determines the price of a custom piece?
A custom jewellery price starts with the amount and type of metal, the chosen stones and the work needed to make the design. ENBOM DIAMONDS normally makes pieces in 18ct gold (18K, 750); 14ct gold (14K, 585) is available on request. A wider, heavier ring needs a different metal allowance from a fine band. A bracelet needs a different construction from a pendant, even if both contain the same total weight of stones.
Carat describes a diamond’s weight, not its width when you look down at it. Shape and cut change how large a stone appears from above. A deep cut can carry weight underneath, where you cannot see it. GIA’s guide to the 4Cs (checked 28 September 2026) explains that carat weight alone does not describe a diamond’s appearance or quality. I look at the cut and dimensions when choosing a stone, rather than treating the carat number as a complete specification.
Colour and clarity can change the stone price too. So can a request for a particular size or shape: we source stones for each piece, subject to availability. Most lab-grown stones I set are VVS1 or VVS2 clarity, but there is no default colour grade. The exact grade of a proposed stone belongs on its quote and, where the stone has an individual report, on that report. Natural stones can also be sourced by request.
Finally, the design determines the work. A plain band, a pendant combining two metals and a bracelet with many bezel settings ask different things of the workshop. Casting, setting and polishing take place in one workshop in Shenzhen. I work directly with the workshops and stone suppliers here, choose the stone myself and visit the workshop to check the work. A useful quote therefore describes the piece you will receive, rather than offering a price based on carat weight alone.
What is included in the quoted price?
The price we give you includes delivery to Australia. You see the price before paying anything, and the quote remains valid for 14 days. Once you decide to go ahead, the USD 200 design payment forms part of that price. It is refundable until work on the 3D model starts; once that work has been done, it is retained. No metal is cast until you approve the model.
Three revisions of the 3D model are included. After model approval, we invoice the balance, due within 7 days. Those are the two payments for the piece: the design payment and the balance. If you request further model revisions, their cost is added to the balance invoice.
A centre stone of 0.30 carat or more comes with its individual laboratory report included in the price. Lab-grown stones come with IGI reports and natural stones with GIA reports. Smaller stones, side stones and pavé stones are not individually reported. That distinction matters when comparing quotes for a ring with one centre stone against a bracelet made up of many smaller stones. Our guide to IGI and GIA reports explains what to check on a stone’s paperwork.
An 18ct piece is stamped 750, and a testing laboratory in China checks the finished piece and issues a certificate for it. Before dispatch, you see photos of the finished jewellery. We carry the risk of loss or damage until the piece is delivered, and remake or refund in full if it is lost or damaged.
Which costs can sit outside the quoted price?
Australian border charges are not one of them. Import duties, GST and clearance charges for delivery to Australia are included in our price, as is delivery itself, so you pay nothing when the piece arrives. We pay those charges on your behalf through the carrier.
Australian Border Force’s GST guidance (checked 28 September 2026) says GST on a taxable import is 10% of its taxable importation value, which can include customs value, duty and international transport costs. With us, that GST is already inside the quoted price. If another seller bills import charges separately, you cannot simply add 10% to their price to predict the amount due: the import treatment and assessed amounts depend on the shipment. This is a dated summary of ABF guidance, not tax advice; the Australian jewellery import guide covers the charges in detail.
Changes to the model can also affect the amount you pay. The first three revisions are included; each further revision costs USD 50 and appears on the balance invoice. The original quote covers the design specified in it, so if you decide on a different stone or a substantially different piece, ask for an updated quote before approving the model.
Both real prices in this article are in US dollars, as quoted. They are not Australian dollar estimates. If you are budgeting in AUD, the conversion you see when you pay may differ from one available when you first read the quote.
Where is it worth spending more on the stone?
I would spend on cut before paying for a clarity or colour difference I cannot see. Two stones can have the same carat weight and look different in size from above. The cut also affects how they handle light. GIA (checked 28 September 2026) notes that diamonds with the same cut grade can still have different face-up appearances, so I want to see the measurements as well as the grade.
If a VS1 or VS2 stone costs noticeably less than a VVS1 or VVS2 stone, I would consider the VS. In most cases, the clarity difference is invisible to the naked eye. That advice still calls for looking at the actual stone: the position of an inclusion and the cutting style can affect what you notice. GIA’s 4Cs guide (checked 28 September 2026) describes why some inclusions show more readily in a step cut than in a brilliant cut.
I would ask the same question about D and E colour. D costs noticeably more, while the difference from E is hard to see once the stone is set. GIA’s colour guide (checked 28 September 2026) says some distinctions between colour grades are invisible to an untrained eye despite affecting price. A higher grade is real information; whether its visible effect is worth the extra cost is a separate decision.
Before paying for any stone, ask for an independent laboratory report, its exact cut and an explanation of what you are paying extra for. A seller’s own certificate is not an independent report. For a simple band, classic studs or a traditional tennis bracelet, I also would not pay extra just for a large brand name.
Are custom engagement rings more expensive than ready-made ones?
Not necessarily. A custom engagement ring is priced from the same three things as a ready-made one: the gold, the stones and the work. What custom adds is design time, and at ENBOM DIAMONDS that is not a separate fee: the USD 200 design payment counts towards the total price, and three revisions of the 3D model are included.
The price rises where the design asks for more: a heavier band, more stones to set, or a stone of a particular size or shape that has to be sourced for your ring. Each model revision after the third costs USD 50 on the balance invoice. The price falls when you change the specification rather than the look: a VS stone instead of VVS, or E colour instead of D, often costs noticeably less without a difference you can see once the stone is set.
When you compare a custom quote with a ready-made ring, compare like with like: the centre stone and its report, the gold purity and weight, and what the price includes. Our quotes include delivery to Australia, and a centre stone of 0.30 carat or more comes with an independent laboratory report. A ring in a shop window can look cheaper or dearer for reasons that sit in exactly those details.
How much would a custom engagement ring cost?
We do not have a ring price to publish, so the USD 950 pendant cannot stand in for one. A ring quote needs a design reference, the finger size, a metal choice, the centre stone and any side stones. The width of the band and the setting also change the amount of metal and work.
Send me a photo, a link or an idea, and I can work with the workshops to see what can be made inspired by your reference. We then give you the price before you pay anything. If you have a date in mind, allow three to four weeks from order to delivery in Australia; the custom ring timeline shows where model approval and production fit.
What does the average engagement ring cost in Australia?
Easy Weddings reports an average engagement ring cost of AUD 6,842 in its 2026 Australian Wedding Industry Report (Easy Weddings, checked 1 October 2026). It is a useful point of comparison, but it is not an average price for a custom ring with a lab-grown diamond. The published figure does not separate those rings from other designs and stones.
An average also cannot tell you what your ring should cost. It brings many different purchases into one number without describing the centre stone, the gold, the setting or the work behind any particular ring. Easy Weddings does not give a separate custom lab-grown ring figure on that page, so I would not turn AUD 6,842 into a target for your quote.
If you are comparing ring quotes, start with the same design and specifications. Ask which centre stone each price covers, what metal and band are proposed, and whether a laboratory report, delivery and any Australian import charges are included. At ENBOM DIAMONDS, delivery is included; a centre stone of 0.30 carat or more comes with an independent report included in the price. Import duties and GST are included in our price too, so you pay nothing on delivery. Those details will tell you more than the national average.
How would a 1.5-carat pair of studs be quoted? A worked example
This is an illustration of the quoting process, not a past order or a priced design. Suppose the request is for a pair of studs described as “1.5 carats”. The first question is whether that means 1.5 carats across the pair or 1.5 carats in each stud. Those are different stone requests, and a number on its own cannot settle the price.
Next, I would need the preferred shape and a photo, link or description of the setting. We would confirm the metal and whether the stones should be lab-grown or natural, then source options that can be made into a matching pair. I choose stones in person. The quote would specify what was selected, what reports apply and the total price in US dollars. It would be free and valid for 14 days.
If you accepted that quote, the USD 200 design payment would start the order. The workshop would make a 3D model for your approval, with three revisions included. Only after approval would we invoice the balance and proceed to make the studs. You would see photos of the finished pair before dispatch. There is deliberately no price attached to this example: until those choices are made, a price would be a guess.
Where do these two prices stop helping?
The USD 950 pendant and USD 3,150 bracelet are prices for two specified pieces, not a price list. They cannot tell you the exact cost of a ring, a different pendant or a tennis bracelet whose stone type and metal have yet to be chosen. They also do not tell an Australian reader the final amount payable at the border.
For a usable number, send me the piece you have in mind as a photo, link or idea. Tell me which details you want to keep and what you are open to changing. We will check what can be made inspired by your reference and give you a free quote before you decide whether to pay the USD 200 design payment. Show me your idea.
Questions
How much is a 1-carat lab-grown diamond pendant?
One real ENBOM DIAMONDS quote was USD 950 for a pendant with a 1-carat lab-grown pear-cut diamond, set in platinum and 18ct yellow gold. That is the price of that particular design, not a standard pendant price. Send us your reference for a free quote based on the stone, metal and setting you want.
How much does a lab-grown tennis bracelet cost?
One real ENBOM DIAMONDS quote was USD 3,150 for a tennis bracelet with bezel-set stones, 2.76 carats in total. A bracelet's price depends on how many stones share that weight, their type and grade, and the metal, so another bracelet needs its own quote. The quote is free.
Is the USD 200 design payment extra?
No. The USD 200 design payment is the first payment toward the total quoted price. It is refundable until work on the 3D model starts and is retained once that work has been done. After you approve the model, you pay the remaining balance. Three model revisions are included; further revisions cost USD 50 each and are added to that balance.
Are custom engagement rings more expensive than ready-made ones?
Not necessarily. Both are priced from the gold, the stones and the work. At ENBOM DIAMONDS the design is not a separate fee: the USD 200 design payment counts towards the total price and three 3D-model revisions are included. Each revision after the third costs USD 50.
Do I pay GST on top of the jewellery price in Australia?
Not with ENBOM DIAMONDS. Import duties and GST are included in the price, as is delivery to Australia, so you pay nothing on delivery. GST still applies to the import under Australian rules; we pay it for you through the carrier.
