You’re planning a proposal and want a ring that feels like yours, not one pulled from a crowded catalogue. But choosing between shapes, settings, metals and diamond grades can be overwhelming—and expensive mistakes are easy. How do you balance sparkle, durability and budget, and still hit your proposal date?

The simplest answer is to create your own engagement ring online, with clear guidance at each step. A Star Diamonds’ ring builder lets you select a setting, compare natural and lab‑grown diamonds in real videos, choose your metal and add personal touches—backed by Hatton Garden craftsmanship, ethical sourcing and lifetime aftercare.

This guide shows you exactly how to design and buy online with confidence: set a budget and timeline, gather inspiration, choose where to start (setting first or diamond first), pick a shape, master the 4Cs, select a setting and metal, refine details, verify certification and sourcing, get the size right, review lead times and insurance, book expert help, and place your order.

Step 1. Set your budget and proposal timeline

Set a clear budget and a realistic timeline before you create your own engagement ring. Start with a total you’re comfortable spending and decide how you’ll split it between the centre diamond and the setting, noting that design complexity and accent stones influence price. Work backwards from your proposal date, leaving breathing room for design sign‑off, crafting, checks, delivery and any resizing. Choosing natural or lab‑grown diamonds will also shape how far your budget goes. With A Star Diamonds, complimentary engraving and lifetime resizing, polishing and cleaning keep long‑term costs down.

• Set the number: Define a clear total and a comfortable upper limit.
• Prioritise spend: Decide whether carat size, cut quality or design comes first.
• Set the date: Work backwards and add a time buffer before your proposal.

Step 2. Gather inspiration and define the ring style

Before you start clicking through an online ring builder, gather visual cues that feel like your partner. Look at the jewellery they already wear, their wardrobe tones and day‑to‑day lifestyle, then save examples of designs you love—classic solitaires, diamond bands, hidden halos or three‑stones—to narrow the look and feel. A simple mood board on your phone will make it quicker to create your own engagement ring with confidence.

• Define the vibe: minimal, vintage‑inspired or modern classic.
• Shortlist shapes: round, oval, emerald, princess, radiant.
• Band and setting: plain or diamond band, low‑set for active lifestyles.

Step 3. Choose your starting point: setting first or diamond first

When you create your own engagement ring online, you can start with the setting or the centre stone. There’s no fixed order—begin where your priorities are clearest. A Star Diamonds’ builder supports both, and our Hatton Garden team fits every setting to your stone’s exact measurements.

• Start with the setting if: your partner’s style is clear (solitaire, diamond band, hidden halo), you need a low‑profile or flush‑fit, or the metal and band width come first.
• Start with the diamond if: carat, shape and cut drive value, you want to compare stones in videos, or you’re chasing a look (oval, round, emerald) and need the head built to exact measurements.

Step 4. Decide between natural and lab-grown diamonds

Both natural and lab-grown diamonds are real diamonds—the difference is origin. Natural diamonds form in the earth; lab-grown diamonds are created in controlled conditions. A Star Diamonds offers ethically sourced natural and 100% conflict-free lab-grown options, supported by expert gemmologists and crafted in UK-made settings. Both can look exceptional when well cut, so when you create your own engagement ring, choose the origin that fits your values, the look you love and the story you want to tell.

• Natural – rarity and tradition: Earth-created, ethically sourced, classic symbolism.
• Natural – heirloom appeal: Favoured if you value a storied, geological origin.
• Lab-grown – 100% conflict-free origin: Modern, science-led creation with clear provenance.
• Lab-grown – wider, consistent choice: Available across a broad range of shapes and sizes.

Whichever you prefer, both can be set in any A Star design and come with lifetime resizing, polishing and cleaning. With origin decided, the next choice is your diamond shape.

Step 5. Choose a diamond shape

Shape sets the ring’s character, finger coverage and the style you want. Start with the look your partner gravitates to, then consider how they wear their jewellery daily. Brilliant‑cut shapes (round, oval, radiant) maximise sparkle; step‑cuts (emerald, Asscher) give clean flashes that reward good clarity. Shapes with corners or points need protective claws and may suit a lower profile. When you create your own engagement ring online, preview how each shape pairs with solitaires, diamond bands and hidden halos.

• Round Brilliant: timeless, versatile and balanced; suits almost any setting.
• Oval: elongates the finger with generous spread and elegant profile.
• Emerald: step‑cut clarity, sleek lines and quietly refined presence.
• Asscher: square step‑cut symmetry, bold facets and Art Deco character.
• Princess: crisp square brilliance; protect corners with V‑claws, set low.
• Radiant: rectangular brilliance with trimmed corners for extra durability.

Step 6. Understand the 4Cs and how to prioritise them

Mastering the 4Cs is how you control beauty per pound when you create your own engagement ring. Cut drives sparkle and light return; carat sets presence on the hand; colour reflects how white or warm the diamond appears; clarity describes the visibility and position of natural inclusions. Balance them and you’ll get show‑stopping impact without overspend.

In practice, prioritise what changes the look most. For brilliant cuts (round, oval, radiant), top cut quality makes the stone sing even at a slightly smaller carat. For step cuts (emerald, Asscher), crisp clarity matters more. Metal influences colour: white metals highlight tint; yellow/rose gold soften it. Use A Star Diamonds’ videos and gemmologist guidance to confirm performance and an eye‑clean appearance. That way, your budget backs what you can actually see.

• Cut first: Make cut your non‑negotiable; seek excellent proportions, symmetry and polish for lively sparkle.
• Carat for presence: Decide the visual size you want; ovals and radiants offer more spread than rounds.
• Colour to metal: Near‑colourless looks icy in platinum/white gold; warmer tones sit beautifully in yellow/rose gold.
• Clarity that’s eye‑clean: Brilliant cuts hide inclusions better; step cuts show them. Avoid obvious inclusions near princess corners.
• Use the setting: Halos and diamond bands add brightness, letting you go slightly warmer in colour or smaller in carat.

Step 7. Select a setting style that suits the shape and lifestyle

When you create your own engagement ring, the setting is where your vision meets daily wear. Think about routine—keyboards, gym sessions, gloves, travel—and how much height and sparkle you want. Low‑set profiles glide through life; classic prong solitaires maximise light and look airy. Hidden halos add discreet fire beneath the centre; diamond bands bring all‑round shimmer but need more care. Match shape to protection: pointed or cornered stones benefit from secure claws; elongated shapes often sit a touch lower for stability. Our Hatton Garden goldsmiths tailor each setting to your diamond’s exact measurements and can ensure a flush fit with a future wedding band.

• Solitaire/prong: Timeless and bright; perfect when the diamond is the hero.
• Diamond band: Extra sparkle; choose durable pavé if you’re hands‑on.
• Hidden halo: Clean silhouette with surprise sparkle; great for round and oval.
• Halo: Boosts visual size and protection; helpful at lower carat weights.
• Bezel (rubover): Smooth, secure, low snag; ideal for active lifestyles.

Step 8. Choose your metal and finish

Metal sets the mood, durability and how white your diamond appears. Look at what they already wear (yellow, rose or silver‑tone), how hands‑on their day is, and the upkeep they’ll accept. Finish then refines the vibe—from mirror‑polish to satin—when you create your own engagement ring.

• Platinum: naturally white, dense, hypoallergenic; robust prongs; develops a soft patina.
• 18ct White Gold: rhodium‑bright; lighter and lower cost than platinum; needs replating.
• 18ct Yellow or Rose Gold: warm tones flatter many skin tones and slightly tinted diamonds.
• Finishes: high polish for shine; satin/brushed hide micro‑scratches; match the wedding band.

Step 9. Finalise design details: prongs, profiles, hidden halos and diamond bands

With the headline choices set, the finer details turn a pretty ring into one that wears beautifully every day. Decide how the stone is held, how high it sits, and where any extra sparkle lives. These choices affect security, snag potential, wedding‑band fit and care. When you create your own engagement ring with A Star Diamonds, our Hatton Garden goldsmiths tailor claws, profiles and pavé to your diamond’s measurements and lifestyle.

• Prongs/claws: 4‑claw shows more; 6‑claw adds security. Use V‑claws on corners; pick rounded, talon or double claws.
• Profile/height: Low baskets are glove‑friendly; cathedral shoulders add lift. Confirm a flush‑fit with the future wedding band.
• Hidden halo: A micro hidden halo adds side sparkle yet keeps a clean solitaire look; ensure cleaning access.
• Diamond band coverage: Half or three‑quarter bands enable resizing; full eternity maximises sparkle but restricts future adjustments.
• Band setting style: Pavé/micro‑pavé shimmers; shared‑claw looks airy; channel is smooth and durable for daily wear.

Step 10. Compare and select your diamond online

With your shape chosen, compare stones in the builder. Set filters for budget, carat and the 4Cs, then shortlist three to five. Use the 360-degree videos to judge sparkle, facet pattern and whether the diamond looks eye‑clean at normal viewing. Open the specs to check millimetre measurements (not just carat) so you know face‑up size and how it will sit in your chosen setting. When you create your own engagement ring with A Star Diamonds, we build the head to your stone’s exact dimensions. If you’re torn between two stones, our gemmologists can help you choose the stronger performer.

• Measure, don’t guess: Use mm dimensions to gauge face‑up size and finger coverage.
• Prioritise cut: Fancy shapes don’t have standard grades—rely on video brightness and even pattern.
• Spot red flags: In elongated shapes, avoid heavy “bow‑tie” shadows; look for balanced light.
• Aim for eye‑clean: Favour inclusions near the edge that can sit under prongs; avoid surface‑reaching.
• Buy what you see: Choose the stone that looks brightest and most generous to the eye within budget.

Before you check out, you’ll confirm the paperwork and origin—next, verify certification and ethical sourcing.

Step 11. Check certification, videos and ethical sourcing

When you create your own engagement ring online, certification is your safety net. Your diamond should have an independent grading report from a recognised lab. Cross‑check the report number, the 4Cs and millimetre measurements against the product page, and view the laser inscription (where applicable). Keep a digital copy for insurance.

Then trust your eyes. Use 360‑degree videos and high‑resolution images to judge brightness and inclusion visibility at normal viewing distances. If anything feels borderline, A Star Diamonds’ gemmologists can talk you through the footage so you pick the best‑performing stone.

• Independent lab grading: e.g., GIA/IGI; match the report number and laser inscription.
• Specs match the report: 4Cs and millimetre measurements should align with the listing.
• Video check: even brightness, avoid heavy bow‑tie in elongated shapes, eye‑clean at normal viewing.
• Ethical origin and craft: ethically sourced natural and 100% conflict‑free lab‑grown diamonds, UK‑made in Hatton Garden.

Step 12. Get the right ring size

Size is comfort—and the difference between a seamless proposal and a scramble to resize. If you’re planning a surprise, you can still get close. And when you create your own engagement ring with A Star Diamonds, lifetime resizing lets you propose and perfect the fit afterwards.

• Borrow a ring: Measure inside diameter in mm; we can convert to a UK size.
• Get professionally sized: Visit Hatton Garden for precision, or book virtual guidance.
• Between sizes? Go slightly larger: Wider bands feel tighter; avoid full eternity bands if unsure.

Step 13. Add personal touches: engraving and matching bands

Personal touches turn a beautiful ring into a story you wear. As you create your own engagement ring, choose the engraving and plan the matching wedding band so both sit and shine together. A Star Diamonds includes complimentary engraving—pick a message, font and placement—and our Hatton Garden goldsmiths shape bands to fit your setting.

• Engraving ideas: initials, date, coordinates, or a short motto.
• Match the band: metal colour, width, profile and finish.
• Flush fit: straight, curved or notched band; choose pavé coverage.

Step 14. Review lead times, delivery and insurance

Production time is real when you create your own engagement ring: bespoke settings, diamond setting, pavé work, engraving and quality checks all add days. Confirm the estimated lead time early and build a buffer so your proposal date isn’t tight. Decide whether you’ll collect in Hatton Garden or arrange courier delivery, and line up insurance to protect the ring from the moment it’s in your care.

• Lead times: Confirm timelines for crafting, stone setting, engraving and QC; ask if expedited options are possible if you’re close to a deadline.
• Delivery/collection: Confirm insured transit, tracking and signature on delivery, or book safe in‑store collection.
• Insurance: Arrange cover effective from dispatch/collection; request purchase documentation and grading report details; note the laser inscription and photograph the ring.
• Travelling to propose: Check customs rules and travel insurance; never put the ring in checked luggage.

Step 15. Book expert help (virtual or Hatton Garden) and place your order

Before you check out, get a final sense‑check from an expert. Book a virtual appointment or visit Hatton Garden to confirm your diamond choice, setting, metal and sizing, and to lock in lead times. Bring your shortlist and any ring size notes—our gemmologists and goldsmiths will verify measurements, ensure a flush wedding‑band fit and answer last questions. Then you can place your order with confidence and keep the paperwork ready for insurance.

• Book help: Schedule a virtual consult or Hatton Garden visit (or message via phone/WhatsApp) with your shortlist.
• Confirm specs: Diamond origin, shape, carat, 4Cs, mm dimensions; setting, prongs, height; metal and finish; engraving.
• Verify documents: Grading report number and ethical sourcing; order summary with estimated completion date.
• Place the order: Choose delivery or collection, save confirmations and invoices for insurance.

Step 16. Care for your ring: cleaning, resizing and lifetime benefits

The “yes” is only the start—care keeps your ring bright and secure. Diamonds are tough, but metal and claws do the daily work. Keep a simple routine and book periodic TLC. When you create your own engagement ring with A Star Diamonds, you get lifetime free resizing, polishing and cleaning, with Hatton Garden experts ready to check the setting.

• Daily habits: Remove for gym, gardening, swimming; avoid lotions; store separately.
• Clean at home: Warm water, mild washing-up liquid, soft brush; rinse and dry.
• Professional TLC: Book cleaning; we’ll check claws and alignment and refresh polish—free for life.
• Resize when needed: Seasons change fit; visit anytime for complimentary resizing.
