Heart-shaped lab diamonds that speak the language of love — worn every day or saved for the moments that matter most.

The heart cut is the most romantic of all diamond shapes — a modified brilliant featuring a distinctive cleft at the top and 56–58 precision facets that produce exceptional scintillation. In lab-grown form, grown via CVD technology, heart-cut diamonds are chemically and optically identical to mined stones, certified to the same standards by GIA and IGI. Achieving a perfectly symmetrical heart requires master cutting, which is why the Cœur Lumière Studs are graded and inspected individually before pairing.

Cœur Lumière Studs — Heart-Cut Lab Diamonds in 18kt White Gold
The Cœur Lumière Studs are a rare achievement: two heart-cut CVD lab diamonds, perfectly matched in cut symmetry, colour, and brilliance, set in a clean 4-prong 18kt white gold mounting that frames the shape without distraction.
Heart-cut diamonds are among the most demanding to cut — the cleft must be precise, the two lobes perfectly equal, and the point sharp but not fragile. Each diamond in this pair meets an exceptional D colour, VVS1 clarity standard, meaning no visible inclusions even under 10× magnification. The result is extraordinary brightness from ear to ear.
CVD lab growth ensures a traceable, conflict-free origin at a fraction of the cost of mined equivalents. Both stones are graded by GIA and IGI, giving you the highest level of independent assurance in the industry.
- Perfectly matched pair — symmetry, colour, and cut graded as a set
- D colour, VVS1 clarity — the finest available in a stud earring
- 56–58 precision facets per stone — maximum heart-shape brilliance
- CVD lab-grown — real diamonds, traceable ethical origin
- GIA and IGI grading certificates included for both stones
- 18kt white gold with butterfly push-back — secure all-day wear
- 60–75% less than equivalent mined heart-cut diamonds

Caring for Your Cœur Lumière Studs
Heart-cut diamonds, with their pointed base and delicate cleft, reward careful everyday handling. Your 18kt white gold setting is durable and secure, but a few simple habits will keep your studs looking exceptional for life.
Daily Wear: The Cœur Lumière Studs are designed for all-day wear. The butterfly push-back is secure; press firmly until you hear a click. Avoid tugging earrings out — always release the butterfly first to protect the post.
Cleaning at Home: Soak in warm water with a small drop of mild dish soap for two minutes, then use a soft toothbrush to gently sweep the back of each stone and around the prongs. Rinse and pat dry with a lint-free cloth. Do this monthly to maintain maximum brilliance.
What to Avoid: Remove before swimming (chlorine and saltwater are harsh on gold), before applying perfume or hairspray, and before sleep to prevent snagging. Avoid home ultrasonic cleaners, which can loosen prongs over time.
- Complimentary professional cleaning and prong check annually
- Re-rhodium plating available on request — keeps white gold bright
- Store in the original presentation box or a pouch to prevent contact scratches

Questions
Frequently Asked
Everything you need to know about the Cœur Lumière Studs before you buy.
Yes. Each pair is hand-selected from a graded inventory to ensure matched symmetry, cut proportion, colour (D), and clarity (VVS1). Heart-cut stones are particularly sensitive to asymmetry, so our gemologists inspect each pair side-by-side under magnification before shipping. The result is a visually identical pair that reads as one cohesive jewel from across a room.
The heart shape requires significantly more rough material to cut — the distinctive cleft and two equal lobes demand precise craftsmanship, and more of the original rough is lost in the process compared to a round brilliant. Add the difficulty of finding and matching two heart stones of equal proportions for a stud pair, and you understand why heart-cut earrings of this quality are rare. Our lab-grown process still saves you 60–75% versus mined equivalents of the same grade.
The price covers the full pair of earrings (both stones and both settings), the GIA grading report for each stone, the IGI certificate for each stone, complimentary engraving on the butterfly backs, the luxury navy presentation box with champagne tissue insert, DHL Express insured shipping to your door, and our 60-day return guarantee. There are no hidden fees.
Absolutely. The 4-prong 18kt white gold setting is designed for secure all-day wear. The butterfly push-back clicks firmly into place and resists accidental loosening during daily activity. We recommend removing them before swimming and sleeping, and avoiding contact with perfume and hairspray — not because the setting is fragile, but to preserve the exceptional polish and rhodium finish long-term. With basic care they will look perfect for decades.
A well-cut heart shape is a spectacular stone — its 56–58 facets follow the same brilliant cutting principles as the round, producing strong light return and vivid scintillation. Because the outline is irregular, the heart creates a more dispersed, romantic pattern of sparkle rather than the tight, symmetrical flashes of a round. At D colour and VVS1 clarity, there is nothing in the stone to impede the light — every facet fires cleanly. The result is a distinctive, deeply expressive brilliance that round and oval cuts simply cannot replicate.
