Hi all, great informative site for us who recently started appreciating gemstones (a longer way of saying 'beginner' i guess ), so there goes my first post:
1- I read somewhere that Columbian miners call cheap dull emeralds 'Murrala'. Now, is this term directly referring to a somehow bad 'transparency'? (In other words, lesser transparent an emerald, the duller it is, right?)
2- I know the term 'Transparent to translucent' to describe transparency of a stone. (I've heard it in description of bixbite's transparency) So, is it ok to assume for a bixbite that IT IS more valuable when its transparency is 'TRANSPARENT', and it is less valuable when it is transparency is more of 'translucent'?...(Assuming their color/clarity are similar)
Hope it makes sense. Thanks in advance for your answers...

'Murrala'... = wall. The name could be a metaphor for opaque, dinghy looking stones... more suitable for masonry than gems. That's just using translation, never heard of the term in relation with precious beryl or gemstone of any kind.

Hi Barbra & Valeria,
Thanks for your answers.. I think i got the answer I was looking for; relation between the 'dullness' and the transparency... One final question:
True or false: Transluency is basically 'lesser' transparency...?!

How about something MORE than opaque? A substance SO inhibitive of transmission of visible light that it actually blocks light AROUND it, not just passing through it?
