Diamond Fields and Values The following table provides more information for some of the diamond fields in the Tracr Data Dictionary. | Field name | Description | Allowed values | | ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | cut\_grade | The grade of cut. |

I= Ideal, ID
EX = Excellent, EXC
VG = Very Good
G = Good
F = Fair
P = Poor

| | colour |

This field is auto-generated based on the defined colour of the diamond. It cannot be set via the API but will be returned in both the rough and polished data for any given diamond accessed via the API.

For white diamonds the value will be the same as the defined colour (D-Z scale).

For fancy coloured diamonds (those with at least fancy\_colour and fancy\_colour\_intensity) the value will be a human readable representation of the diamonds fancy colour (e.g. Fancy Dark Greenish Blue).

|

Examples:

White Diamond: D

Fancy Colour: Fancy Dark Greenish Blue

| | colour | The colour of the non-fancy polished diamond. |

D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z
For fancy colours, use the fancy colour columns.

| | clarity | The relative absence of inclusions and blemishes. |

FL, IF, LC, VVS1, VVS2, VS1, VS2, SI1, SI2, SI3, I1, I2, I3, P1, P2, P3
For fancy coloured stones without clarity, enter "N" for none.

| | symmetry | The symmetry of the polished diamond. |

I = I, ID
EX = Excellent, X
VG-EX = Very Good to Excellent, VGEX
VG = Very Good, V, V. Good, V.G
G-VG = Good to Very Good
G = Good
F-G = Fair to Good
F = Fair
P= Poor

| | polish\_quality | The quality of the polished diamond. |

I = I, ID
EX = Excellent, X
VG-EX = Very Good to Excellent, VGEX
VG = Very Good, V, V. Good, V.G
G-VG = Good to Very Good
G = Good
F-G = Fair to Good
F = Fair
P= Poor

| | fluorescence\_intensity | The colour of the diamond when viewed under long-wave ultraviolet light. |

B = Blue, BL
W = White, WH
Y = Yellow, YL
O = Orange, OR
R = Red
G = Green, BG
N = None, NIL, NON

| | fancy\_colour | The colour of the diamond if fancy. |

BK = Black
B = Blue
BN = Brown
CH = Chameleon
CM = Champagne
CG = Cognac
GY = Gray, Grey
G = Green
O = Orange
P = Pink
PL = Purple
R = Red
V = Violet
Y = Yellow
W = White, WH
X =Other, OT

| | fancy\_colour\_intensity | The intensity of fancy colour. |

F = Faint
VL = Very Light
L = Light
FCL, FL = Fancy Light
FC = Fancy, FC
FCD = Fancy Dark
I = Fancy Intense
FV = Fancy Vivid
D = Fancy Deep, DP, Deep

| | girdle\_condition | The condition of the girdle. |

P = Polished
F = Faceted
B = Bruted
The girdle is the section of a diamond that separates the top part of the diamond (the crown) from the bottom part (the pavilion).

| | culet\_size | The size of the culet. |

EL = Extremely Large
VL = Very Large
L = Large
SL = Slightly Large
M = Medium
S = Small
VS = Very Small
N = None
The culet is the facet at the very bottom of the diamond.

| | culet\_condition | The condition of the culet. |

P = Pointed
A = Abraded
C = Chipped

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.tracr.com/tracr-user-guide/9.-diamond-fields-and-values.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
