If you are wondering can I send a loose diamond to a jeweller for setting, the short answer is yes. Many jewellers regularly set customer supplied diamonds into engagement rings, wedding bands, pendants, and other jewellery. However, not every jeweller accepts outside stones, and there are several important factors to consider before sending your diamond.
Choosing the right jeweller, understanding their policies, and ensuring your diamond is properly certified and insured can make the entire process straightforward and stress free. Whether you have recently purchased one of today's loose lab diamonds or already own a family stone, knowing what to expect will help you make an informed decision.

Can You Send a Loose Diamond to Any Jeweller?
While many jewellers are happy to work with customer supplied diamonds, not all offer this service.
Some jewellers specialise in bespoke jewellery and regularly set loose diamonds, while others only work with diamonds purchased directly from their own inventory. This policy often exists because they can only guarantee workmanship on stones they have sourced themselves.
Before sending your diamond, always confirm:
- Whether they accept customer supplied diamonds
- Which diamond shapes and sizes they can set
- Their setting fees
- Their insurance and liability policies
- Estimated turnaround time
Checking these details beforehand helps avoid unexpected delays or additional costs.
Why People Buy the Diamond First
Buying the diamond separately has become increasingly popular, especially with lab grown diamonds.
Purchasing the diamond first allows you to:
- Compare more diamonds before making a decision
- Prioritise quality within your budget
- Choose the exact shape and carat size you want
- Select a ring design afterwards
- Work with a trusted local or specialist jeweller
Many buyers appreciate having complete control over both the diamond and the final ring design instead of selecting a ready made ring.

What Happens Before the Diamond Is Set?
Professional jewellers usually inspect every loose diamond before beginning work.
The inspection typically includes:
Checking the Diamond Certificate
Most jewellers will verify the grading report from recognised laboratories.
For lab grown diamonds, this commonly includes certificates detailing:
- Carat weight
- Cut
- Colour
- Clarity
- Measurements
- Laser inscription (if applicable)
Having certification provides confidence that the stone matches its grading information.
Inspecting the Diamond's Condition
The jeweller examines the diamond under magnification to check for:
- Chips
- Existing scratches
- Girdle damage
- Natural inclusions that may require extra care during setting
This protects both you and the jeweller by documenting the stone's condition before work begins.
Choosing the Right Setting
Not every diamond works equally well with every ring style.
The setting should complement both the diamond's shape and your lifestyle.
Popular engagement ring settings include:
Solitaire
A timeless option that highlights the centre diamond.
Hidden Halo
Adds extra sparkle while maintaining a classic appearance.
Halo
Creates the illusion of a larger centre stone by surrounding it with smaller diamonds.
Three Stone
Represents the past, present, and future while adding additional brilliance.
Bezel
Offers excellent protection by surrounding the diamond with metal.
If you have not yet chosen your ring, you can compare styles before making your final decision.

Are Lab Grown Diamonds Easy to Set?
Yes. Lab grown diamonds are physically real diamonds and are set exactly like mined diamonds.
A professional jeweller uses the same techniques, tools, and craftsmanship regardless of how the diamond was created.
The setting process does not change because the diamond is laboratory grown.
This makes loose lab diamonds an excellent choice for bespoke engagement rings.
How Should You Send a Loose Diamond?
If your jeweller accepts deliveries, proper shipping is extremely important.
Consider the following precautions:
- Use insured shipping
- Require signature on delivery
- Never label the package as containing jewellery
- Keep the grading certificate separate if requested
- Photograph the diamond before shipping
- Keep copies of all documentation
Many customers also prefer hand delivering valuable diamonds whenever possible.

Questions to Ask Before Sending Your Diamond
Every jeweller has different policies, so ask these questions first.
Do You Accept Customer Supplied Diamonds?
This is the most important question to ask before placing an order.
Is My Diamond Fully Insured While in Your Care?
Understand exactly when responsibility transfers between you and the jeweller.
What Happens if the Diamond Is Damaged?
Although professional setters are highly experienced, accidents can occasionally happen.
Ask about:
- Insurance coverage
- Replacement policies
- Liability limits
- Repair procedures
How Long Will the Process Take?
Setting times vary depending on:
- Ring design
- Custom manufacturing
- Availability of the setting
- Quality control inspections
Simple settings may take only a few days, while fully bespoke rings can require several weeks.
Is It Better to Buy the Diamond and Ring From the Same Place?
There are advantages to both approaches.
Buying everything together may offer:
- Simpler ordering
- One warranty
- Easier communication
- Faster completion
Buying the diamond separately offers:
- More choice
- Better price comparisons
- Greater flexibility
- Access to a wider selection of certified diamonds
There is no single right answer. The best option depends on your priorities, budget, and preferred ring design.
How to Choose the Best Loose Diamond Before Setting
If you are still shopping, focus on more than just carat weight.
Compare every diamond using the Four Cs:
Cut
Excellent cut quality has the greatest impact on sparkle.
Colour
Near colourless grades often provide exceptional value while appearing white in most settings.
Clarity
Many VS and SI diamonds appear eye clean while costing less than higher clarity grades.
Carat
Choose a size that fits both your budget and preferred ring style.
Comparing multiple certified diamonds often helps you find better overall value.
If you are deciding between several options, explore our Compare Prices guide to see how different combinations of cut, colour, clarity, and carat affect value.

Should You Choose a Local Jeweller or an Online Jeweller?
Both options have advantages.
A local jeweller allows you to:
- Meet the setter in person
- View ring samples
- Discuss custom designs
- Deliver the diamond yourself
An online jeweller may offer:
- Larger inventories
- Competitive pricing
- Remote consultations
- Convenient shipping options
Choose whichever gives you greater confidence, clear communication, and transparent policies.
Common Mistakes to Avoid
Many buyers can avoid unnecessary problems by planning ahead.
Common mistakes include:
- Sending a diamond without confirming the jeweller accepts outside stones
- Forgetting to insure the shipment
- Choosing a setting that does not suit the diamond
- Ignoring certification
- Comparing diamonds based only on carat weight
- Not reviewing warranty and liability policies
A little preparation helps ensure the process goes smoothly.
