it would help to know if you are looking for natural diamond
crystals- raw diamonds- as opposed to graded diamond rough, which is
a different creature and comes in industrial to gem quality grades.
I, and I’m sure many Orchideans know of many suppliers of all the
types, grades, price ranges and personability of the
dealers/businesses that sell the stuff. so For me a bit narrower a
description would help me point you in at least one direction. I
personally LOVE raw diamond crystals, also called rough diamonds by
some. they come in colours from grey to “salada”: a reference to
fruit salad, since the crystals in their natural form can be pale
oranges, pinks, yellows, greens, browns, etc. to the greys and blacks
of natural stones as they come from the earth. Additionally, raw
diamond crystals can be had in almost any shape you desire from
octahedral to square, etc. I3 diamond rough sounds like you could
potentially save some money getting industrial grade material but
that’s only necessary if you want fairly eye clean material that has
visible inclusions ( though minuscule or appearing as a black spot
somewhere in the stone)…so if no one else offers the info you want
with a bit more clarification I can help. rer
