Grading

CARATS

The Carat is the measure of the actual weight of the diamond. A carat is divided into 100 points. A 0.50 carat diamond may also be referred to as 50 points.
Stones that have too high a depth percentage carry more weight in the height of the diamond where it does not add to the visual size appearance.

COLOR

Diamond color is all about what you can’t see. Lesser the color, higher their value.On the basis of color, diamonds are allocated a grade, starting with D,representing colorless, and continue with increasing presence of the color to theletter Z.

CLARITY

Diamonds are formed under extreme heat & pressure, deep within the earth, thus they often contain birthmarks, either internal or external. Diamonds with less birthmarks are rare, and rarity affects its value. Diamonds are allocated a grade, which ranges from FL (no inclusions) to I3 (obvious inclusions).

CUT

The cut is the most important element which reflects its brilliance, sparkle, fire and scintillation, which is mostly determined by 3 factors, proportion, polish & symmetry. Each diamond is assigned an overall cut grade from Excellent to Poor.

ID – IDEAL

G – Very Good

FR – Fair

ID – IDEAL

G – Very Good

FR – Fair

POLISH

All facets of a diamond are carefully polished to eliminate all imperfections, characteristics such as abrasions, scratches, nicks and polishing marks on the surface of the diamond to give the mirror shine and the final beauty touch.

EX – Excellent

GD – Good

VG – Very Good

SYMMETRY

Symmetry is the balance and regularity / evenness of facets.
Facets are compared in opposing pairs, defined as following:

EX – Excellent

GD – Good

VG – Very Good

BIT

BT0 – Black Table 0

BT2 – Black Table 2

NV – None Visible

BT3 – Black Table 3

BT1 – Black Table 1

BIC

BC0 – Black Crown 0

BC2 – Black Crown 2

NV – None Visible

C3 – Black Crown 3

BC1 – Black Crown 1

WIT

WT0 – White Table 0

WT2 – White Table 2

NV – None Visible

WT3 – White Table 3

WT1 – White Table 1

WIC

WC0 – White Crown 0

WC2 – White Crown 2

WC3 – White Crown 3

WC1 – White Crown 1

INCLUSION PATTERN

S1 – Scattered Inclusion

C1 – Light Concentrated Inclusion

S2 – Semi Scattered Inclusion

C2 – Semi Concentrated Inclusion

C3 – Concentrated Inclusion

INCLUSION PATTERN

Fluorescence, the effect ultraviolet (UV) light has on a diamond, is an important consideration when selecting a diamond. When UV light strikes a diamond with fluorescent properties, the stone emits a glow that is usually blue, but can also reflect shades of green, yellow, white, pink, orange, and red. The sources of fluorescence, boron and nitrogen, are the same mineral properties that lend color to a diamond. Fluorescence can occur in different intensities. Gemological laboratories rate the fluorescence of each diamond on a scale from “None” to “Very Strong”
