rough looks like is the subject of this month's lead article. This
up when a reader made a comment and asked a question...
occasion you refer to gemstone rough, or gem rough. What is it, what makes

gemstones begin as crystals - but a few are organic (pearls, coral,
amber) or rocks, such as turquoise or lapis-lazuli (below).

rough, what I picture in my head is a piece of transparent, facet grade
crystal exhibiting pleasing color.
As we know from high school,
crystals grow in one of several shapes - or crystal growth habits.
rough is the crystal (or rock) that nature produces. That
natural piece of material may be "worked" by a human hand to
trim away host rock or "cob" away unwanted portions of the
crystal. The term rough makes reference to the unfinished state of the
does Gemstone rough looks like is the part of the question most people
find more interesting. I once asked a group
where I was speaking to describe several pieces of uncut gemstones
rough looks like several things depending on the shape the crystal adopts
as it grows.
I showed the group a natural garnet crystal, they decided it looked like a
tiny, red soccer ball (above).
I showed them a natural tourmaline crystal, they said it looked like a
green pencil (top).
I showed them a natural sapphire crystal, they said it looked like a
pretty rock. Because the sapphire crystal was mined from an ancient stream
bed, it was water worn to the point that no crystal faces were apparent.
I showed them a parcel of natural emerald crystals, they thought the pieces looked
like broken, green safety glass. Unbroken emerald crystals exhibit the
hexagonal crystal shape.
I showed them an aquamarine crystal specimen in matrix, they said it looked like a
mish-mash of crystals.
I showed them a piece of lapis-lazuli, they said it looked like a blue

Visitor Returns $32 Million Bag of Diamonds at HK
The International Diamond Exchange website ran a feel good
story about a lucky, but apparently distracted diamond dealer - and a very
(IDEX Online News) – A diamond dealer had a lucky
escape after leaving a bag of diamonds worth $32 million in a café at the Hong
Kong Jewellery & Gem Fair.
Fortunately for the unnamed Israeli trader, the bag of
diamonds was found by Shenzen tourist Fu Zhuli, who not only returned the gems,
but also told off the dealer for being so careless in the first place, reports
the Shenzhen Daily.
Fu told the paper that she had decided to take a break
at the show and sat down in one of the fair’s cafes. She saw two foreigners
chatting and only once they had left did she see that they had left a black bag
After opening the bag, the jewelry enthusiast found “a
trove of good quality, soy-bean-sized roughs.”
She guarded the bag for two hours until one of the
foreigners ran back into the café.
“The shirt on his back was soaked with sweat, and his
face was pale. He rushed in and saw the bag with me and leaned forward, uttered
some incoherent words and kept bowing and saying ‘thank you’ in Putonghua,”
she said. “I told him off for being so careless and leaving something so
precious behind,” reported the Shenzen Daily.
