IGI Certified Lab Grown Diamond Engagement Rings

A ring is chosen once and worn every day after. Growing the stone rather than mining it changes nothing about what it is — only how much of it a given budget will carry onto a hand.

In Brief

Every ring in this collection is set with a single lab-grown diamond in solid 14K gold, and each one includes its own IGI certificate. Six cuts — round, oval, princess, radiant, emerald and cushion — at 1.00, 1.50, 2.00, 3.00 and 5.00 ct, with G–H color and VS1–VS2 clarity throughout. Rings are stocked in sizes 3 to 9; prong work and rhodium re-plating are covered by the lifetime warranty, and one resize is included free.

Lab-Grown and Natural Diamonds, Compared

Both are diamond. The difference is where the carbon crystallised, and what that changes is grading, cost, and the carat weight within reach at a given budget.

Lab-GrownNatural
CompositionChemically, physically and optically identical. Origin is the only difference.Crystallised carbonCrystallised carbon
GradingIndependently graded. Single-stone pieces — engagement rings, studs — include an individual IGI certificate; tennis bracelets and eternity bands come with an AGI certificate.Conflict-free and responsibly sourced.
Cost at equal specificationThe figure DEEVE states storewide.Approximately 70% lessMarket price
Carat weight within a given budgetHigher — a full eternity band at 2 to 8 carats stays within reachLower at the same specification
Hardness and daily wearNo difference in durability.10 on the Mohs scale10 on the Mohs scale

Neither is the better stone. Lab-grown suits a larger carat weight within a set budget, and arrives independently graded — with an individual IGI certificate on single-stone pieces and an AGI certificate with every tennis bracelet and eternity band. Natural suits a preference for a stone formed over geological time, and is conflict-free and responsibly sourced. The choice is one of priority, not quality.

The DEEVE Standard

Every DEEVE engagement ring is crafted in solid 14K gold — lab-grown diamonds IGI-certified with the certificate included, or natural diamonds that are conflict-free and responsibly sourced. Each ring carries a lifetime warranty covering prong retipping and stone resetting, serviced in our Ontario workshop, with one resize included free, free insured express shipping and 30-day returns across Canada and the US.

About this collection

A lab-grown diamond is the same stone by every measure that decides how a ring looks and lasts — the same carbon lattice, the same hardness, the same fire. What changes is what comes within reach at a given budget.

Every ring here is set with a single lab-grown diamond and made in solid 14K gold. The collection is built as a grid rather than a scatter: six cuts — round, oval, princess, radiant, emerald and cushion — at five carat weights from 1.00 to 5.00 ct. Color is G–H and clarity VS1–VS2 across all thirty, so what is actually in front of you is a choice of shape and scale, not a spec sheet.

Available Specifications
  • Carat: 1.00, 1.50, 2.00, 3.00 and 5.00 ct center stones
  • Cuts: Round, oval, princess, radiant, emerald and cushion
  • Color: G–H (near-colorless)
  • Clarity: VS1–VS2 (eye-clean)
  • Diamond type: Lab grown, IGI certified — the certificate ships with the ring
  • Metal: Solid 14K white or yellow gold
  • Sizes: 3 to 9, with half sizes on most designs
What the Certificate Covers

Each ring here is a single-stone piece, so each carries its own IGI certificate — a record of that exact diamond's cut, color, clarity and carat weight, rather than a sample or a range. Our guide to reading an IGI certificate walks through the document field by field.

Sizing, Fit and Aftercare

Rings are stocked rather than made to order, so your size ships as it is. Prong work and rhodium re-plating are carried out by our in-house workshop and covered by the lifetime warranty, and one resize is included free; additional resizes are chargeable. Confirm your size against the jewelry size guide before ordering. If the ring you have in mind is not here, our bespoke service makes it to order — two to six weeks depending on the design.
