The round brilliant cut is the most scientifically optimised diamond shape ever devised — its 57 or 58 facets are precisely calculated to maximise light return, fire and scintillation. First engineered by Marcel Tolkowsky in 1919, the round brilliant became and remains the world's most purchased diamond cut. In stud form it is unmatched: a circle of light that suits every face shape, sits flush against the ear, and works effortlessly from casual mornings to black-tie evenings. Each of our lab-grown round brilliant stones is cut to Excellent proportions with a table percentage and depth angle tuned for maximum brilliance. Paired by our gemologists for identical table width, colour and clarity so both ears read as a perfect match.

Round Brilliant Diamond Stud Earrings

Nothing in fine jewellery is more timeless than a pair of round brilliant diamond studs. The round cut's 57 precisely angled facets return the highest percentage of incident light of any diamond shape — making these the brightest, most scintillating studs you can wear. Set in a clean 4-prong basket that holds each stone securely while keeping the full face visible, they deliver an intense circle of fire against the ear.

Our CVD lab-grown round brilliants are cut to Excellent grade proportions — the same standard as the finest mined diamonds — at a fraction of the cost. Each pair is selected from stones that match in table width within 0.2mm, ensuring both earrings appear identical when worn. Available from 0.50ct total weight through 1.50ct, in 18K white, yellow or rose gold.

  • Matched pair — identical cut proportions, table width and colour
  • Round brilliant — maximum fire and scintillation of any cut
  • 4-prong open basket setting
  • D–E colour, VVS/VS clarity throughout
  • CVD lab-grown — real diamonds, traceable ethical origin
  • IGI grading certificate for the pair included

Caring for Your Round Brilliant Diamond Earrings

Round brilliant studs are extremely robust but benefit from a simple cleaning routine to maintain their brilliance. The 4-prong basket setting can accumulate natural oils which reduce the light return of the stone.

Cleaning: Soak both earrings in warm soapy water for 2–3 minutes. Use a soft brush to clean gently around each prong and under the stone's pavilion. Rinse thoroughly under running water and pat dry before storing.

Prongs: Check the 4 prong tips annually. A bent or worn prong tip can allow a stone to loosen. Our atelier offers complimentary annual inspections and free re-prong service within 2 years of purchase.

  • Complimentary prong inspection annually
  • Re-rhodium plating for white gold available on request
  • Store each earring in the padded box — never loose
