What we supply
Small goods, taken seriously.
Six things, all of them natural, all of them cut on our own floor. Tell us the sieve sizes and colour range you work in and we will quote against live stock or cut to order.

−2 and Below
The sizes most houses subcontract. We cut, sort and sell them ourselves, so the sortment matches the packet.

Sizing reference
Sieve, millimetre, carat.
The three ways the same stone gets described, side by side. Weights are typical for a well-proportioned round brilliant and will move a little with make.
| Sieve / trade name | Diameter | Approx. weight | Stones per carat |
|---|---|---|---|
| −2 and below | 0.80 – 1.00 mm | 0.003 – 0.005 ct | 200 – 330 |
| Star (+2 −4) | 1.00 – 1.25 mm | 0.005 – 0.010 ct | 100 – 200 |
| +4 −6 | 1.25 – 1.50 mm | 0.010 – 0.015 ct | 65 – 100 |
| +6 −8 | 1.50 – 1.80 mm | 0.015 – 0.025 ct | 40 – 65 |
| +8 −10 | 1.80 – 2.10 mm | 0.025 – 0.035 ct | 28 – 40 |
| +10 −12 | 2.10 – 2.50 mm | 0.035 – 0.055 ct | 18 – 28 |
| +12 −14 | 2.50 – 2.90 mm | 0.055 – 0.080 ct | 12 – 18 |
| Above melee | 3.00 mm and up | 0.10 ct and up | Sold by the stone |

Grading ranges we hold
Say the range once. We keep it.
These are the ranges we stock and can repeat season to season. Anything outside them we will cut to order rather than substitute quietly.
Colour
D–F, G–H and I–J held as separate sortments. Below J we quote by parcel rather than by range, because the eye stops agreeing with the chart.
D–FG–HI–J
Clarity
VVS, VS and SI. At melee sizes clarity is judged on the whole parcel under 10× rather than stone by stone, which is why the sortment discipline matters more than the label.

Cut
Full cut, fifty-seven facets, held to a single make across the parcel. Single cut (seventeen facets) available where a design calls for it — asked for, never substituted.

How a parcel arrives
Sealed, weighed, and written on.
Every parcel leaves sieve-sorted and sealed, with the sortment, weight and piece count written on the packet — not on a separate note that gets lost in transit. Larger stones travel with their independent lab report and, where inscribed, the report number on the girdle.
Dispatch is insured door to door. We ship on your account or ours, whichever you prefer, and we send the airway bill the same day it moves.
