Lab-Grown Diamond Ring Resale Value: What Australian Buyers Should Know

As Lab-Grown Diamonds continue to grow in popularity among Australian couples, the question of what the diamond will be worth in years to come has become just as important a factor when purchasing a diamond ring as the initial cost of the diamonds themselves.

While lab-grown diamonds have similar physical and visual properties to natural diamonds, they generally are priced lower than their natural counterparts. In many cases, this means the buyer can purchase a larger diamond or look at spending more of the budget on the ring’s design and the craftsmanship.

It is worth noting however that the retail price of lab grown diamond jewelry is not the resale value of said item.

The Australian market for lab grown diamonds has grown considerably in recent years and there are a number of different sellers who supply these diamonds to customers looking to purchase an engagement ring. We look at lab grown diamond ring resale value in Australia and the factors that affect this.

Do Lab-Grown Diamond Rings Have Resale Value?

Lab-Grown Diamond Rings do have resale value; however, the resale value will always be less than the original price that was paid for the ring.

The resale market does not look at a second-hand ring in the same way that you did at time of retail sale. The original retail price of a ring contains a lot more than the price of the diamond alone.

• Diamond grading and certification

• Gold or platinum

• Ring design

• Manufacturing and craftsmanship

• Retailer overheads

• Warranties and aftercare

• Packaging and presentation

• Business margins

As a used ring, none of these costs are factored into what a used ring is sold for.

The buyer in the second-hand market is interested in the value of the diamond(s) and the setting(s)  not the value of what the seller paid for the item some time ago.

As mentioned above, most Australian retailers will quote you the ‘Retail’ price, the ‘Insurance’ valuation (which is the cost to replace the item through retail stores) and then the ‘Resale’ value that you will get for it when you sell it back through second-hand stores.

Why Can Lab-Grown Diamond Resale Values Be Lower?

The decrease in the cost of production of new diamonds.

Lab-grown diamonds are manufactured in controlled laboratory environments and as the cost of producing new lab-grown diamonds has decreased with improving production technology and increased competition in the market, the wholesale price has dramatically fallen.

The 2026 De Beers Diamond Report describes the wholesale prices for synthetic diamonds (lab-grown diamonds) to have declined by 93% between 2020 and 2026, averaging US$100 per carat in wholesale in the market data covered in the report.

When it comes to reselling your lab-grown diamond rings a number of years down the line, the wholesale price has dramatically decreased.

For example, if you purchased a diamond in 2026 for a particular amount and a few years later the same diamonds are sold in the wholesale market for substantially less then it will affect the resale value of your used diamonds.

How Much Will You Get for Your Lab-Grown Diamond Ring?

There is no standard Australian resale percentage for Lab Grown Diamond Rings.

Resale of Lab Grown Diamonds: Retail Selling Prices are reported to be returned at 10–20% of the Retail Selling Price for some Lab Grown Diamonds reported by some Australian Jewellery Retailers. It must be noted that there are exceptions to this rule and that Resale of some Jewellery will return more than this whilst others will return less.

Your actual offer will be higher or lower than this depending on the individual circumstances.

For example, a simple solitaire ring would likely get a better price than an unusual / very personalized design.

The selling method also matters.

The price a specialist diamond buyer offers will allow for his own costs and margin. He is likely to offer less than you can get in a private sale but the process is very quick and you are not left to organize authentication, payment etc.

What Affects the Resale Value of a Lab-Grown Diamond?

Many factors determine how much someone is willing to pay for a used diamond.

1. Diamond Quality

The diamond's 4Cs still matter:

• Cut

• Colour

• Clarity

• Carat

In most cases, a well-cut stone of good visual quality will command a higher price than a stone of similar carat weight that was chosen solely on basis of carat weight.

2. Certification

A recognised grading report can make the resale process easier.

This allows future buyers to verify the stone’s characteristics.

So retain the original grading report with other relevant papers and maybe refer to the laser inscription in the diamond and the details recorded in the report.

3. Current Lab-Grown Diamond Prices

This is one of the most important factors.

It will get compared to new, lab-grown diamonds of similar specifications.

A new grown diamond may be sold for less price than your second-hand diamond, so you have to offer it on the lower price as well.

4. Ring Condition

The condition of the whole ring, including the band, stones, engravings, and other features, is important when considering resale value.

Scratches to the band, worn polish to the metal work, loose stones, damaged settings, and even the absence of stones such as side stones can greatly affect the way a ring is perceived by potential buyers.

It makes a better second-hand product if it has been properly maintained.

5. Metal Type

The setting has its own material value.

Platinum and gold in the setting of a ring has material value, but the original retail cost of the setting will not be fully recovered from a second-hand sale.

Also remember the cost to make a ring is not recovered in the second-hand sale of that ring.

6. Ring Design

Classic designs are generally easier to sell as they are sought after by a wider audience.

Personalized pieces, unusual engravings or especially exotic jewelry styles may have a smaller market of potential buyers for pre-owned jewelry.

This does not mean that personal or bespoke designed jewelry is bad to resell though. Everyone’s taste with jewelry is different so it is just important to remember that when selling used jewelry online that there is a chance that not everybody will like it as much as you do.

7. Selling Channel

Where you sell can make a significant difference.

You may consider:

• A specialist diamond buyer

• A jeweller's trade-in programme

• Consignment

• A private sale

• A second-hand jewellery marketplace

The price you will get from a quick dealer sale will reflect their purchase price and their aim to make a profit when they in turn sell on.

You may get more views on a private sale, but generally that will need a lot more time and effort from you in approaching potential buyers.

Lab-Grown vs Natural Diamond Resale Value

This is where buyers often get confused.

Natural diamonds have been sold in the second-hand market for a long time but not every natural diamond is an investment.

Natural diamond jewelry can be sold for less than the retail value of the new jewelry.

Lab-grown diamonds also have an increased supply of new production entering the market, which in the last year or so has seen significant price decreases in wholesale lab-grown diamonds.

So the comparison is not simply:

• Natural = investment

• Lab-grown = no value

The reality is more nuanced.

Both Natural and Lab-Grown diamonds are sold as jewelry first and as investment/s later. The future resale value of any diamond depends upon many factors including market conditions, diamond specifications, jewelry design, condition, demand, and others.

Should You Buy a Lab-Grown Diamond as an Investment?

For most Australian buyers, no.

Lab-grown diamonds should be purchased because of their quality (i.e. their diamond characteristics), and because of the value of the jewelry as a whole – ie its aesthetics and craftsmanship – as well as the purchase price.

Just because you buy a lab-grown diamond as an investment, does not mean you will make a profit when you sell it.

The price of wholesale lab-grown diamonds has dropped dramatically in the last few years, and this is a factor that the potential investor should take into account when deciding whether or not to invest in a lab-grown diamond.

That does not make lab-grown diamonds a poor choice.

In fact, the lower purchase price is one of their biggest advantages.

Instead of spending more money on a smaller diamond, you can spend your budget on a larger diamond and use the rest of the money to buy a nicer setting, more metal etc..

The value of purchasing a lab grown diamond is the value of what you purchase with your money, not the potential return on investment.

How Australian Buyers Can Protect Future Resale Options

Even though the price of resale will be unknown, the verification of and potential selling of lab-grown diamonds can be made easier by documenting and caring for the diamond.

Keep Your Documents

Save:

• Original invoice

• Diamond grading report

• Warranty documents

• Insurance valuation

• Repair records

Any documentation showing the ring's specifications

Good documentation helps to protect future resale by enabling prospective purchasers to more readily understand what they are buying.

How to Look After the Ring?

Check the setting regularly, especially if you wear the ring daily.

Loose claws or damaged settings should be addressed before they become larger problems.

Avoid Unnecessary Damage

Take off your ring before activities that can risk strong impact, exposing it to harsh chemicals or excessive wear and tear.

Understand Your Insurance Valuation

Don’t use your insurance valuation to estimate the future resale value of a ring.

Insurance and resale serve different purposes.

Get More Than One Offer

If you eventually decide to sell, compare several offers from specialist buyers, from local high street Jewellers, from on-line Consignment Houses and from private sellers.

They may offer you different sums of money for your ring as they will charge you different amounts for their services.

What Should You Look For When Buying a Lab-Grown Diamond Ring?

If you don’t care about resale, then look for the best diamond for the money you spend.

Start with the cut and then look at overall appearance of the diamond. A very nice looking diamond that performs well visually can be more satisfying to wear than a diamond that has the highest specifications possible.

Then consider:

• Your preferred diamond shape

• Carat size

• Colour

• Clarity

• Certification

• Metal type

• Setting security

• Ring design

• Aftercare

• Warranty

Make Sure to Keep a Check on The jeweller's reputation

Most importantly, compare the total value of the ring as opposed to just comparing carat weight of the purchase.

The Bottom Line for Australian Buyers

Lab-grown diamond rings can be a wonderful option to consider when buying diamonds and seeking to retain some of the dollars spent on the initial purchase while still receiving the beautiful diamonds and their attributes that you are seeking to purchase.

But resale should be approached realistically. A lab-grown diamond ring is jewellery, not a guaranteed financial asset. The future value of your lab-grown diamonds can be affected by the current price of new lab-grown diamonds, current market demand, the specifications of the diamonds, certification of the diamonds, the condition of the jewelry, the type of metal used in the jewelry and the method of sale.

When purchasing a ring to wear, it is often the beauty of the diamond, the meaning behind it, and the wearability that counts, and therefore means that a lab-grown diamond is often sold at a lower purchase price.

Comparing long term market behavior of different diamonds is best to assess their value for price preservation. Buy what you love at a price you can afford to pay. And consider the resale value as a bonus that may or may not be realized at a later date.
