FOR THE MOMENT THAT FEELS DISTINCTLY YOURS
Some diamonds whisper.
This one lingers.
The elongated cushion combines soft curves with a graceful silhouette, creating a presence that feels both romantic and refined.
Elegant.
Individual.
Quietly captivating.
Not chosen to follow tradition.
Chosen to express it differently.
Love the design, but want something different?
You can order your chosen Aurelion design online. Selected adaptations may be possible before production begins. Alternative carat sizes, natural diamonds and refined design details can be discussed with our Private Client Service.
Personal guidance. Transparent pricing. No obligation.
Choose options
The solitaire is the purest expression of an engagement ring.
With nothing to distract from the centre diamond, every detail is chosen to enhance its brilliance, presence and beauty.
Timeless in design. Refined in every detail.
A certificate confirms a diamond's grade. It does not tell the whole story of how the stone actually looks.
We begin with our core standard — lab-grown diamonds in the D–E colour range, VVS clarity — then assess the factors that determine visual performance: cut and proportions, symmetry, polish, light return, face-up spread and overall balance.
For fancy shapes such as oval, pear, cushion and emerald, we also look closely at outline, length-to-width ratio and shape-specific characteristics such as distracting bow-tie or windowing where relevant.
Only diamonds that satisfy both our technical standards and our visual judgement are approved for an Aurelion piece.
Brilliance, Curated.
Every diamond of 0.70 ct or more in the Aurelion Collection is accompanied by its own IGI grading report. For earrings, this applies to each stone individually, not to the combined weight of the pair.
Diamonds below 0.70 ct and smaller accent diamonds are selected to the same standard, without an individual report. The report for your diamond is confirmed in your order confirmation and can be verified in IGI's online database.
Crafted by experienced artisans in Antwerp, each piece is created with precision and care.
From the selection of the diamond to the final polish, every stage reflects our commitment to exceptional quality and enduring elegance.
Available in solid 18K white, yellow or rose gold.
Crafted for your order
Aurelion Collection pieces are crafted for your order rather than taken from finished jewellery stock. After your order, your diamond is selected and your piece is individually assembled, set by a goldsmith and finished in Antwerp.
Selected adaptations may be possible before production begins. If you would prefer a different carat size, a natural diamond or a refined change to the design, contact our Private Client Service to discuss the possibilities before production begins.
Aurelion Final Inspection
Before any Aurelion piece leaves us, it undergoes an individual final inspection.
We check the security and alignment of the centre diamond, prongs and settings, inspect all accent diamonds where applicable, verify the finish, symmetry and product specifications, and review the completed piece as a whole.
Only when the piece meets our standards is it approved for dispatch.
Selected with care. Inspected with purpose.
Your piece is crafted after your order and dispatched within the period shown in the product information: usually 7 working days, with selected pieces taking 2–4 weeks. Transit time begins after dispatch and depends on your destination. You will receive tracking information as soon as your piece is on its way.
Would you prefer a natural diamond or a different carat size? Selected alternatives and refined adaptations may be possible before production begins.
Our Private Client Service can discuss suitability, availability and a personalised quotation. More extensive requests can be explored through Bespoke.

Frequently Asked Questions
Most pieces from the Aurelion Collection are crafted for your order rather than taken from finished jewellery stock. After your order is placed, your diamond is selected and your piece is assembled, set by a goldsmith, finished and individually inspected before dispatch.
Selected adaptations may still be possible before production begins. Contact our Private Client Service if you would like to discuss a different carat size, natural diamond or refined design detail.
Pieces from The Vault are different: these are singular pieces that have already been crafted and are offered as shown.
Absolutely. Lab-grown diamonds are chemically and visually identicalto mined diamonds — the difference lies only in origin.
Every diamond of 0.70 ct or more in the Aurelion Collection is accompanied by its own IGI grading report. For earrings, this applies to each stone individually, not to the combined weight of the pair.
Diamonds below 0.70 ct and smaller accent diamonds are selected to the same standard, without an individual report. The report for your diamond is confirmed in your order confirmation and can be verified in IGI's online database.
Our Solitaire rings offer complimentary personal engraving inside the band: a meaningful date, initials or a short message of up to 20 characters. For other pieces, please ask our Private Client Service whether engraving is available for your selected design before production begins.
Engraving does not change the stated production time for Solitaire rings.
A personal engraving may fall within the legal exception for clearly personalised goods, as explained before ordering. Your statutory rights for faulty or non-conforming goods remain unaffected.
Delivery is available to supported EU destinations. For delivery outside the EU, please contact our Private Client Service before ordering; availability and arrangements require confirmation.
Shipping costs are shown before you place your order. Import duties, customs charges and local taxes outside the EU are not included unless expressly confirmed. Every shipment is fully insured for its purchase value, tracked and delivered against signature, both inside and outside the EU.
Pieces from the Aurelion Collection are crafted after your order and are usually dispatched within 7 working days; selected pieces take 2–4 weeks. The estimate for each piece is shown in the product information. Vault pieces have already been crafted and are dispatched within 2 working days.
Transit time begins after dispatch and depends on your destination. You will receive tracking information when your piece is dispatched. Contact our Private Client Service before production begins if you have a particular date in mind.
Personalised and individually made items
A piece ordered using our standard Collection options remains a normal Collection product, even when it is crafted after your order. Choosing an available carat size, gold colour or standard ring size does not, by itself, make the piece personalised. Crafted to order does not, by itself, exclude return rights.
Where the statutory right of withdrawal applies, you may withdraw without giving a reason within 14 days after you or your nominated recipient, other than the carrier, receives the goods. Notify us by a clear statement at concierge@aureliondiamonds.com before the period expires; no prior authorisation is required. Return the goods within 14 days after notifying us.
The statutory right of withdrawal is excluded only where a legal exception applies, including goods genuinely made to your individual specifications or clearly personalised, such as jewellery with a personal engraving. Choosing standard options or production after ordering alone does not establish an exception. Any applicable exception is explained before you order.
For Bespoke orders, the withdrawal position depends on the actual individual specifications or personalisation. The Bespoke label alone does not remove statutory rights.
This does not affect your statutory rights if an item is faulty, incorrectly supplied or does not conform to your order.
If your piece has a manufacturing or technical defect, we will of course take full responsibility and repair or replace the item at no cost.
Eligible, non-personalised Collection jewellery qualifies for our additional exchange service. Submit your request no later than 30 calendar days after receipt. From day 15 this service provides exchange only, without an additional right to a refund. Your item does not need to have reached us by day 30; return instructions and the shipping deadline follow approval. The Vault and genuinely personalised products are excluded from this additional service. Statutory rights remain unaffected.
For this service, jewellery must be unworn, undamaged, in original condition, complete with certificates and documentation, and in its original packaging where reasonably applicable. Pieces with personalised engraving, individual modifications outside our standard Collection options, and Bespoke pieces are not eligible.
Refunds are made without undue delay and no later than 14 days after we are informed of your decision to withdraw. We may withhold reimbursement until we have received the returned item or you have provided evidence that it has been sent back, whichever occurs first.
For a change-of-mind return, you bear the direct cost of returning the item. This does not apply where an item is faulty, incorrectly supplied or does not conform to your order; your statutory rights in those cases remain unaffected.
Our team is available for personal guidance before and after your purchase. Simply contact us — we’re happy to help.
