DID YOU KNOW?

DIAMOND COLOUR   =   LACK OF COLOUR

A diamond's colour is essentially by it's absence of colour.
Following the GIA diamond colour-grading system, the degree of colour range from D(colourless) to Z (faint or right yellow).

Here at Michael Trio, we carry diamonds of colour ranging from D to J.

BUT HOW DO YOU CHOOSE?

COLOUR RANGE
(D - M)

D
COLOURLESS
The Highest-quality color grade - a
D-grade diamond is extremely rare and emits unrivalled brilliance.
E
COLOURLESS
Contains minute traces of color. E-graded diamonds also rare, and emit a high level of brilliance.
F
COLOURLESS
Contains minute traces of color that can only be detected by a trained gemmologist. A high-quality color grade.
G, H
NEAR COLOURLESS
Has noticeable color only when compared with higher color grades diamonds. otherwise both grades appear colourless to the untrained eye, and are of excellent value.
I, J
NEAR COLOURLESS
Has slightly detectable colour. Both grades also typically appears colorless to the untrained eye and are of excellent value.
K, L, M
FAINT YELLOW
Faint color is noticeable. However, even with colour presence, these diamonds can emit fire and beauty.

SELECTING A
COLOUR GRADE

Colour plays a crucial role when choosing a diamonds,
especially since it's noticeable to the untrained eye.

TIPS AND THINGS TO NOTE

COLOURLESS DIAMONDS

Those who prefer a colorless diamond should select a stone in the D-F range witha fluorescence rating of "None" or "Faint".

MISCONCEPTION

A common misconception is that only diamonds excude brilliance.

In reality, a well diamond can emit fire and beauty even with trace if faint yellow, although the presence of color will decrease the stone's value.

NEAR COLOURLESS DIAMONDS

Near Colorless diamonds witha rating between G and J are excellent values, as their color is typically undetectable to the unaided eye.

If you are considering a diamond in this color range, a Brilliance diamond and jewellery expert can review the stone to ensure the color cannot be seen with the naked eye.

BRIGHTER APPEARANCE

A near colorless diamond can appear whiter when set in white gold metals. Yellow gold settings complement diamonds with lower color ratings.
Compared to other shapes, brilliant round cut diamonds of all color grade appear brighter due to their greater light dispersion.

FLUORESCENCE

WHAT?
AN EFFECT ULTRAVIOLET (UV)
LIGHT HAS ON A DIAMOND
When UV light strikes diamonds with fluorescent properties, the stone emits a glow that is usually blue.
Howeve, it can also reflect shades of green, yellow, white, pink, orange and red.
The presence of fluorenscence can enhance the visual appeal of a diamond with a lower colour reting in the J through M range.

Fluorenscence also helps to cancel out any faint yellow visible in a stone, resulting in a colorless appearance.

INTENSITIES

Fluorescence can occur in different intensities. Gemological laboratories rate the fluorescence of each diamond on a scale of None, to Very String.
1
No fluorescence,
no colour influence
NONE, NIL, NEGLIGIBLE
2
Week fluorescence,
insignificant colour influence
FAINT, SLIGHT
3
Average fluorescence,
small colour influence
MEDIUM
4
Strong fluorescence,
substantional colour influence
STRONG, EXTREMELY STRONG

THE FLUORESCENCE EFFECT

Fluorescence can enhance or detract from the beauty of a diamond. The bluish tint can improve a lower-color diamond (J-M color rated) by cancelling out the faint yellow, resulting in a colorless appearance.

However, in a very high-color diamond (D-F color rated), fluorescence may have the opposite effect.

HOW DOES FLUORESCENCE AFFECT PRICING?

Historically, strongly fluorescent diamonds have been marked down in price next to their non-fluorescent counterparts.
Typically, higher color (D-H) non-fluorescent diamonds will sell for 10-30% more than similar stones that exhibited very strong blue fluorescence.
However, lower color (I-N) diamonds with very strong fluorescence were priced 5% higher than similar non fluorescence stones. This could be due to the perception that blue fluorescence can mask the undesirable yellow tones found in some stones.
