Serving global jewellery markets
Mira Gems supplies certified lab-grown diamonds to companies across the jewellery value chain. Our diamonds are used in fine jewellery, bridal collections, fashion lines, luxury watches, and industrial applications.
Fine jewellery brands
Solitaires, three-stone rings, tennis bracelets.
Certified single stones supplied to grade, with a full IGI report on every diamond. Colour-locked lots mean a repeat order matches the first, so a collection can stay in production for years without a visible grade drift.
- Round, oval, emerald, pear
- D–J colour, IF to SI2
- IGI report per stone
Bridal jewellery manufacturers
Round and fancy shapes, the 1 to 5 carat core.
The weight range that carries bridal. We supply in single-grade parcels or mixed lots, whatever your production run needs, in all major cuts with certification on every stone.
- 1.00 to 4.99 ct
- All major cuts
- Single-grade or mixed parcels
Fashion jewellery
Melee, calibrated rounds, pavé-grade supply.
Matched calibrated lots for pavé, channel and invisible settings, sorted for consistent colour and clarity so a setter is not fighting the parcel.
- 0.005 to 0.18 ct
- Matched calibrated lots
- D–H colour, VS–SI
Luxury watch manufacturers
Diamond-set bezels, dial diamonds, calibrated stones.
Watch work is a tolerance problem before it is a diamond problem. We cut to specification and sort to size, so stones seat without rework on the bench.
- Calibrated to specification
- Tight size tolerance
- Matched sets
Online jewellery retailers
Certified single stones and production lots.
Every stone ships with its grading report, so a listing carries the certificate a customer expects to see before they buy. Stock is available as single stones or in production lots.
- IGI certified, every stone
- Single stones or lots
- Full grading data
Independent jewellers
Custom studios and bespoke commissions.
Stone by stone, for the one-off commission. Custom cuts are produced to client specification, subject to order requirements and our manufacturing schedule.
- Custom shape requests
- Single-stone supply
- Bespoke specification
Industrial applications
Cutting, grinding, tooling.
Where hardness is the specification rather than brilliance. Lab-grown diamond is the same material as mined, with the same physical properties, produced to a repeatable standard.
- Cutting and grinding
- Tooling grade
- Repeatable supply
