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 / IdealMaximum brilliance
Very GoodHigh brilliance
GoodGood sparkle, more affordable
Fair / PoorLess 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 FColourless — Premium and rare
G to JNear Colourless — Excellent value, recommended
K to ZFaint 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 / IFFlawless — Extremely rare
VVS1 / VVS2Very slight inclusions — Luxury range
VS1 / VS2Slight inclusions, not visible to naked eye — Most popular
SI1 / SI2Visible under magnification only
I1 to I3Clearly 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 ctDelicate everyday elegance
0.50 ctClassic and visible brilliance
0.75 ctPopular statement piece
1.00 ctThe most coveted milestone
