General Information
Diamonds are usually colourless. However, brown, yellow, green, blue,
pink, red, grey and black variations are also found depending on the
impurities present.
Our Diamond Buying
Guide has extensive information and hints on buying diamonds.
Coloured diamonds are often irradiated or painted.
Generally, diamonds are quite durable. However, diamonds are subject
to chipping and fracture when handled roughly. Diamonds should be stored
separately. Diamonds can scratch other jewellery as well as each other.
Reputable dealers will not use the following misleading terms when
discussing diamonds. For your protection, I am listing them here:
"Alaska diamond", "Alencon diamond",
"Arkansas diamond", "Bohemian diamond",
"Bristol diamond", "Cornish diamond", "Irish
diamond", "Isle of Wight diamonds", "Marmora
diamond", "Mexican diamond" and "Vallum
diamond" are really rock crystal (quartz)
and NOT real diamond.
"Ceylon diamond" and "mature diamond" designate
colourless zircon.
"Jourado diamond" is an imitation colourless stone.
"Killiecrankie diamond" and "Saxony diamond"
designate colourless topaz.
"Radium diamond" is really smoky quartz.
"Alaska black diamond" is really hematite.
"Nevada diamond" and "Nevada black diamond"
designate obsidian.
