What do YOU feel is an acceptable emerald enhancement

What do we now consider an acceptable treatment (dare I say desireable)? Lets assume that the dealer states openly its treated with: Cedarwood oil? Polymer that wont fade and IS removable? Opticon? Does the choice of what type of treatment affect value- i.e. if treated with cedar oil its worth so much per carat, and if treated with opticon its worth (less? more?) Thanks, Mayacamas

Richard Hughes Cut Rock Total Posts: 320 Last Post: 10/14/2008 Member Since: 9/27/2004	If I am going to own a treated emerald (and virtually all of them are), I would prefer to have one that has the fractures/fissures filled with a hardened resin, such as that used by Arthur Groom. This resin is far more stable than unhardened resins (such as Opticon) or oils (such as cedarwood oil). While we are on the subject of emerald treatments, I should mention that the term "natural oil" is an oxymoron. The very process of treating an emerald is not a natural process. Thus it is ridiculous to suggest that the insertion of a "natural" oil is somehow better. Richard W. Hughes "The price of wisdom is beyond rubies" Ruby-Sapphire.com

Sellers I've talked to tout the 'natural oil' treatment as better than resin treatment - as it is much closer to "natural" emerald (even though resin filling will definitely be more stabilizing). They were drawing parallel to 'low heat' to corundums vs. Beryllium enhanced treatment.

The less needy emeralds seem to come oiled rather than treated with permanent filler. The reason I've been given for this is that the temporary treatment can be removed upon buyers' request. At a first glance, it appears reasonable to use different treatments according to need. I cannot know if this is just a local oddity. Is it ?
