3.00 ct Round Lab Grown Diamond Eternity Ring in 14K White Gold: diamond weight 3.00 ct (minimum 2.96 ct), diamond cut Round Brilliant, diamond color F–G (colorless to near-colorless), diamond clarity VS2–SI1 (very slightly to slightly included), laboratory certificate AGI (Accredited Gemological Institute). $3,391.00 CAD. Made to order, allow two to six weeks; free insured delivery, no duties in Canada or the US, 30-day returns (30% restocking fee, made to size) and a lifetime warranty. Comes with an AGI certificate.

This 3 ct round lab-grown diamond eternity ring sets a continuous circle of round brilliants in curved prongs on solid 14K white gold. The diamonds total a guaranteed minimum of 2.96 ct, grade F–G (colorless to near-colorless) and VS2–SI1 (very slightly to slightly included), and the ring carries an AGI certificate.

Three carats spread around a 3.60 mm band gives noticeably more sparkle than a fine wedding band while staying comfortable for daily wear. It is a classic way to mark an anniversary, worn alone on the right hand or as the partner to an engagement ring.

The stones are lab-grown by CVD. An AGI certificate from the Accredited Gemological Institute documents the grading. At the same size and grade, lab-grown costs approximately 70% less than natural.

Rhodium polish keeps the 14K white gold bright. Order any size from 4 to 9; each one is made to order, and since there is no plain section of metal to work with, the band cannot be resized afterward. The lifetime warranty applies.

The DEEVE Standard

Every ring in this collection is set with lab-grown diamonds — F–G colour, VS2–SI1 clarity — in solid 14K white gold, rhodium polished, never filled or vermeil, and comes with an AGI certificate. Because the diamonds run unbroken the full way around, each ring is made to size rather than resized afterward: sizes 4 through 8 including half sizes, with the emerald cut designs running to size 9. Every ring is made to order in two to six weeks, and sizes beyond that range are made in our in-house Ontario workshop. Every ring carries the lifetime warranty with free insured express shipping and 30-day returns across Canada and the US.

Buying Guide

How to Choose a Diamond Eternity Ring

Sizing comes first with a full eternity band. Because the diamonds continue the whole way around, the ring is made to size rather than resized later — so confirm your size before ordering, and note that wider bands wear snug. Carat weight then sets the presence: 2.00–3.00ct total reads as a fine, everyday line; 4.00–5.00ct is the balanced middle; 6.00–8.00ct makes the band the centrepiece, with width scaling from roughly 2.9mm to 6.4mm alongside it. Finally, choose the cut — round brilliant carries classic fire, while emerald cut reads as a calmer, architectural line of light. Every stone is F–G colour and VS2–SI1 clarity, set in solid 14K white gold, and every ring comes with an AGI certificate.

FAQ

Questions, answered.

What are the diamond specifications of the 3 ct round eternity ring?

3.00 carats total weight of round brilliant lab-grown diamonds (CVD process), F–G colour and VS2–SI1 clarity, set in solid 14K white gold with rhodium polish. The ring comes with an AGI certificate from the Accredited Gemological Institute.

How wide is the band on the 3 ct round eternity ring?

The band is 3.60mm. This is a step up in presence without crossing into statement territory — the ring registers, and it registers deliberately.

What is the curved arch prong setting on this ring?

Each stone sits under a curved sweep of gold — at this weight the arch detail is a visible design element, giving the band a rhythm beyond the diamonds themselves.

How does the 3 ct round compare with the 4 ct round?

The 4 ct widens to 3.90mm and makes the arch prong architectural. The 3 ct keeps the same design language at a scale that suits daily wear on most hands.

Can the 3 ct round eternity ring be stacked with other rings?

Yes — 3.60mm pairs well with a wedding set, though it is equally at home alone on the right hand.
