Diamonds are very rarely colourless and come in a
range of colours graded from D (colourless) to Z (colours).
Diamond colour at I and J increasingly starts to gain a yellow
tinge which detracts from the sparkling beauty of the diamond.
At these colour levels, the yellow tinge is less noticeable if
the diamond is mounted in yellow gold, but it easily visible
when mounted in white gold or platinum. Therefore, in our
opinion, diamonds mounted in white metal should always be a
minimum of H colour.
However, to ensure that this issue is avoided regardless of the
type of setting, all Samara James certified diamonds are colour
G, H (near colourless) or better. This ensures clear sparkling
brilliance can be assured.
Diamond Gemstones
Diamond is the ultimate gemstone, having few weaknesses and many
strengths. It is well known that Diamond is the hardest
substance found in nature, but few people realize that Diamond
is four times harder than the next hardest natural mineral,
corundum (sapphire and ruby). But even as hard as it is, it is
not impervious. Diamond has four directions of cleavage, meaning
that if it receives a sharp blow in one of these directions it
will cleave, or split. A skilled diamond setter and/or jeweller
will prevent any of these directions from being in a position to
be struck while mounted in a jewellery piece.
As a gemstone, Diamond's single flaw (perfect cleavage) is far
outdistanced by the sum of its positive qualities. It has a
broad colour range, high refraction, high dispersion or fire,
very low reactivity to chemicals, rarity, and of course, extreme
hardness and durability. Diamond is the April Birthstone.
