What is a Solitaire?
A solitaire is a single diamond set alone in a piece of jewellery with no side stones. The purpose is to highlight the full beauty and brilliance of that one exceptional stone.

The 4Cs of Diamonds
Every diamond is graded on four universal parameters — the 4Cs:
1
Cut — The Most Important C
Cut determines a diamond's brilliance and sparkle. A well-cut diamond reflects light beautifully from every angle.
Excellent / Ideal
Maximum brilliance
Very Good
High brilliance
Good
Good sparkle, more affordable
Fair / Poor
Less brilliance, light escapes
KEIAN Luxandor: We use Very Good to Excellent cut diamonds on every piece.
2
Colour
The less colour a diamond has, the rarer and more valuable it is. Diamonds are graded D to Z:
D to F
Colourless — Premium and rare
G to J
Near Colourless — Excellent value, recommended
K to Z
Faint to Light Yellow — Budget-friendly
KEIAN Luxandor recommends: G to J colour for the best balance of beauty and value.
3
Clarity
Clarity measures internal flaws (inclusions) inside a diamond:
FL / IF
Flawless — Extremely rare
VVS1 / VVS2
Very slight inclusions — Luxury range
VS1 / VS2
Slight inclusions, not visible to naked eye — Most popular
SI1 / SI2
Visible under magnification only
I1 to I3
Clearly visible inclusions
KEIAN Luxandor recommends: VS1 to VS2 for the best quality and value.
4
Carat — The Weight
Carat is the weight of a diamond. 1 carat equals 0.2 grams. Larger carat means higher price — but cut, colour, and clarity matter equally.
0.25 ct
Delicate everyday elegance
0.50 ct
Classic and visible brilliance
0.75 ct
Popular statement piece
1.00 ct
The most coveted milestone
Above 1.00 ct
