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.

What 4T™ Is
  • 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.
Scope Limits
  • 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.

01 · Light
Daylight-Balanced
Each stone is assessed under a controlled, daylight-balanced light source, against a neutral reference card. No mood lighting. No tinted gels.
02 · Optics
Close Check + Bare Eye
A jeweller's loupe can reveal detail, but the BE. score is not a diamond clarity grade. We check whether natural features interrupt light, structure, durability, or the way the piece reads at wearing distance.
03 · Reference
Known Specimens
Each material is compared against a kept set of reference specimens for that crystal type. Tone and Transparency are scored against the reference, not against ideal photography.
04 · Record
Lot ID + 4T Row
Scores are written into the Lot record. The same row appears on the product page Stone Origin Card and on your paper certificate. The three must match.

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.

Transparency
Optical clarity of the host crystal
Transparency crystal reference
How clearly light and structure can be read through the stone. Read against a controlled reference card under daylight-balanced lighting. Natural inclusions are acceptable when they belong to the material and do not collapse the optical reading.
5 / Excep.
Eye-clean at wearing distance; light moves cleanly through the body. Minute natural features may appear under magnification if they do not interrupt the reading.
4 / Strong
Slight veiling or small inclusions may appear under close inspection; the stone still reads clean to the unaided eye.
3 / Standard
Visible cloudiness or inclusions are present, but the body remains readable and suitable for wear.
≤ 2
Cloudiness, fracture pattern, or opacity dominates the stone or raises durability concern. Rejected.
Tone
Colour saturation & evenness
Tone crystal reference
How saturated, even, and consistent the colour is across the stone — and, within a strand, bead-to-bead. Banding, zoning, and off-colour regions lower the score. Reference saturations are kept for each crystal type so the standard is not negotiated visually each time.
5 / Excep.
Deep, uniform tone across the full stone. No zoning, no off-colour regions.
4 / Strong
Deep tone with minor zoning visible only on close inspection. Even across the strand.
3 / Standard
Moderate saturation with light zoning. Reads consistent to the eye at wearing distance.
≤ 2
Pale, washed, or visibly banded. Rejected.
Texture
Surface integrity & structural wholeness
Texture crystal reference
The surface finish and structural stability of the stone after cutting and polishing. Natural texture is not automatically a flaw. The question is whether pits, chips, open fractures, or rough finish affect wear, durability, or the visual calm of the piece.
5 / Excep.
Well-polished and stable for wear. No chips or open fractures that affect durability; minute natural surface character may remain.
4 / Strong
Clean polish with small texture marks visible under close inspection. No durability concern.
3 / Standard
Minor pits, nicks, or natural texture may be visible, but the surface remains stable and wearable.
≤ 2
Open cracks, chips, unstable pits, or rough finish affect wear or visual quality. Rejected.
Treasure
Sourcing confidence & material scarcity
Treasure crystal reference
The dimension that cannot be read optically: how confidently the stone's source can be documented, and how scarce the material is at this quality. Documented single-supplier sourcing scores higher than mixed-batch. Unusual formations (e.g. ametrine, phantom inclusions) score higher than common variants of the same species. Treasure is not "value" — it is source confidence and material scarcity.
5 / Excep.
Documented single supplier from a known region. Material formation difficult to replace at the same standard.
4 / Strong
Documented single supplier, known region. Common formation, consistent material quality.
3 / Standard
Documented supplier, region known. Mixed-batch acceptable for materials where mine-level traceability is not commercially available.
≤ 2
Supplier or region undocumented. Rejected.

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.

Tier 01 · Foundation
Studio
All four T's at Standard or above. At least one T below Strong.
  • 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
Tier 02 · Main Line
Signature
All four T's at Strong or above. At least one T below Exceptional.
  • The grade most BE. pieces are built around
  • Visibly distinct from typical industry quality at wearing distance
  • BE.'s recognizable working standard
Tier 03 · Top Reading
Heritage
All four T's at Exceptional for its material type. Documented supplier confidence. Formation difficult to replace at the same 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.

Below BE. Floor · 80%
10%
6%
4%

Accepted 20% — Equivalent Split

Studio

~10% of the whole field. About half of BE.'s accepted stones.

Signature

~6% of the whole field. The middle tier inside BE.'s accepted stones.

Heritage

~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.

01
Find the Lot
Your certificate has a Lot ID printed on it (e.g. BE-AM-1247). The same ID appears in the Stone Origin Card on the product page.
02
Check the Tier
The composite tier (Studio / Signature / Heritage) on your certificate should match the product page card and your order record.
03
Read the 4T Row
Open the Stone Origin Card drawer to see each T's score and the rule that produces your tier.
04
Audit In Person
Use the 4T scales on this page to check the piece in your hand. If you disagree with a reading, write to us — we re-inspect.
