How A Stone Enters BE.
Every BE. stone is read through four material questions before it enters production: how light passes, how colour holds, whether the surface is stable for wear, and whether the material can be replaced at the same standard.
What 4T™ Is.
4T™ is BE.'s documented method for selecting, rejecting, and tiering the stones that enter our pieces. It gives our studio one repeatable language for the four T's — Transparency, Tone, Texture, and Treasure.
- BE.'s internal selection and disclosure method, applied in-studio to every stone.
- A four-dimensional reading — Transparency, Tone, Texture, Treasure — each scored 1–5.
- A three-tier composite — Studio, Signature, Heritage — that appears on each product page.
- A published method, audited against the Lot ID on your certificate.
- Used as a BE. studio standard, not a universal laboratory grade.
- Separate from gem identification and treatment reports where those exist.
- Designed for selection discipline, not price appreciation promises.
- Treatment status is disclosed in plain language when known.
4T™ does not try to make crystal jewellery behave like diamond grading. It gives BE. a clear internal discipline for the kinds of stones we actually work with: beads, cabochons, inclusions, optical effects, and natural variation.
How We Read A Stone.
Every BE. stone is assessed in-studio against the 4T™ standard documented on this page. The method is visual, material, and repeatable: controlled light, close inspection, reference specimens, and a Lot ID record that can be checked against the product page and certificate.
Why Self-Assessed, And How We Stay Honest
Our standard: 4T™ is a studio selection method. Natural stones can carry internal features under magnification. We use magnification as a tool to understand material features, then grade by whether those features affect beauty, structure, wear, and sourcing confidence.
Our trade-off: the method is only as credible as its visibility. So we publish every dimension, every 1–5 criterion, the tier mapping, and the conditions under which a stone is rejected.
The Four Dimensions.
Each T is independently scored on a 1–5 scale. The four scores combine to assign the composite tier on the product page.
From Four Scores To One Tier.
The four T scores combine to assign one composite tier. The rule is weakest-link: the lowest score across the four dimensions governs the tier. A stone is only as strong as its weakest reading. This is the label you see on the product page — three tiers, no inflation, no fifth letter.
- Meets the 4T™ baseline across all four dimensions
- Production-ready; the floor below which no stone enters BE.
- The studio's daily working quality — every piece begins here
- The grade most BE. pieces are built around
- Visibly distinct from typical industry quality at wearing distance
- BE.'s recognizable working standard
- Top reading across every dimension
- Archive-level material — kept, not chased
- Built and intended to outlast its first wearer
The Mapping, Explicitly
| Lowest T (Governs) | Composite Score Range | Pattern | Tier |
|---|---|---|---|
| 5 / Excep. | 20 / 20 | All four T's at Exceptional for their material type. | Heritage |
| 4 / Strong | 16 – 19 | All T's at Strong or above; at least one not Exceptional. | Signature |
| 3 / Standard | 12 – 19 | All T's at Standard or above; at least one not Strong. | Studio |
| ≤ 2 | — | Any T below Standard. | Rejected |
Composite score is informational. Tier is governed by the lowest T. A stone scoring 19/20 with one Standard reading is Studio, not Signature — the weakest link decides.
Where BE. Sits.
Three tiers, one selection rate. The composite tiers explain what makes it into BE. The wider field shows how little of the market does.
How BE. Relates To The Wider Market
One bar · same base: accepted tiers shown inside the whole field.
Accepted 20% — Equivalent Split
~10% of the whole field. About half of BE.'s accepted stones.
~6% of the whole field. The middle tier inside BE.'s accepted stones.
~4% of the whole field. Top reading across every dimension.
Selection Logic
First, BE. filters the wider field. Material below the BE. floor remains outside the system. The accepted field is roughly 20%.
Buyer Read
This view shows Studio, Signature, and Heritage as portions of the same whole-market base. It does not claim that BE. equals Heritage — it shows where each tier sits inside the field BE. has filtered.
Shares are directional, not lab-certified percentages. The whole-market conversion is used to prevent the accepted 20% from being misread as Heritage only.
What Doesn't Make It.
The 80% below the floor fails for specific reasons, not vague ones. Each disqualifying condition below is independently sufficient — a single one rejects a lot, regardless of the other three T's. There is no "BE. seconds" line and no markdown clearance of rejected material.
Disqualifying Conditions
Any single T scoring below Standard. The weakest reading governs. A stone with Exceptional Transparency, Tone, and Treasure but a 2 on Texture does not enter production.
Surface staining or dye. Colour must come from the geology of the stone, not from post-extraction colouring.
Heat treatment, post-extraction artificial irradiation, or any chemical enhancement. Natural radiation during geological formation belongs to origin history. What we exclude is post-extraction, human-applied treatment. If a category's commercial supply is dominantly treated — most citrine, most blue topaz — we either source the rare untreated specimens or do not work with the material.
Undocumented supplier or unclear regional origin. If the lot cannot be traced to a documented source, the stones do not enter production regardless of their optical quality.
Rejected stones are returned to the supplier or set aside for non-production use — reference samples, training material. They do not appear on the website, in sale events, or in any BE. piece.
How To Verify Your Piece.
Every BE. piece ships with a paper certificate. The Stone Origin Card on the product page carries the same Lot ID and the same 4T scores. Three records — certificate, product page, order — must agree.
