Lovenhall Diamond
A digital record for a diamond — detailed macro captures and an AI-assisted reading of cut, colour, clarity and carat, entered in the Registry with its own accession. A considered reading, offered in good faith; not a guarantee.
What a diamond record holds
Every stone is documented, read and entered the same way — a permanent digital dossier you can hold to and share.
Detailed captures
Calibrated macro photography, plate by plate — table, crown, pavilion and the inclusions that make a stone singular.
AI-assisted reading
Artificial intelligence reads cut, colour and clarity indicators from the captures, cross-checked by a trained eye.
Value indication
An indicative market range drawn from the four Cs and recent comparable sales — a guide to worth, never a guarantee of it.
Provenance notes
Grading reports, prior records and the stone's history, recorded alongside it.
Registry entry
A permanent digital record with its own accession number — retrievable, and shareable in confidence.
A note on our recordsA Lovenhall record is an informed opinion — a considered reading supported by detailed imaging and artificial-intelligence analysis, offered in good faith. It is not a certificate of authenticity, a formal appraisal, or a guarantee of value; independent verification is always advised before a purchase or sale.
Capture, analysis, record
Three steps, the same for every piece — from the first calibrated photograph to the entry held in the Registry.
Capture
High-resolution, calibrated photography from every angle — the piece documented in fine detail as it stands today.
Analysis
Artificial intelligence reads the captures alongside our own study — grade indicators for a stone, hand and period for a work — with market comparables gathered.
The Record
The findings are set down as a permanent digital record with its own accession: captures, analysis, a value indication and provenance notes, held in the Registry.

Lovenhall Diamond Identifier
An AI scanner that estimates a diamond's four Cs — colour, clarity, cut and carat — from a photo, then gives a ballpark value range. A fast first look, whether the stone is loose or set in a ring.
- AI estimate of the four Cs from a single scan
- A rough market value range to start from
- Works on loose stones and set rings alike
An indicative first look, not a valuation or guarantee.
The four Cs, and the shape
How a stone is read — cut, colour, clarity and carat, plus the outline you choose. Tap through each to see it.
Cut is what makes a diamond sparkle
Cut is not the shape — it is how precisely the facets are proportioned and polished. A well-cut stone catches light and throws it back through the top as brilliance and fire; a poorly cut one lets light leak out of the sides and bottom, and looks dull however good its other grades.
- Excellent / Ideal cuts return the most light and reward a trained eye more than any other factor.
- Proportions, symmetry and polish are all graded — depth and table percentages matter.
- A higher cut grade can make a smaller or lower-colour stone look livelier than a larger, poorly cut one.
A well-cut stone returns light through the crown; a poor cut leaks it through the base.
On the reading of diamonds
A short reference from the house — the questions we are asked most, answered plainly.
- Carat sets the starting point, but cut, colour and clarity move the figure far more than weight alone.
- Value is anchored to recent comparable sales — like for like on grade, shape and certification.
- Certification from a respected laboratory typically lifts confidence and price; an uncertified stone is discounted for the doubt.
