Re-polishing question- Chrono can you chime in?

[dtnyc]

Has anyone ever had a stone re-polished?
If so by who?

I really want to have my e-ring re-set/adjusted and I am wondering if it would help my center stone to have it re-polished. I don''t have any great pics of it, but it does have some wear on it and small chip on the bottom of the girdle- I don''t know if polishing would take care of the chip at all, but it would help w/ the "wear" on the edges of the facets right?

I don''t even know where to begin or who to ask to do something like this...

It is very unusual for a diamond to need repolishing - sapphires and other gems yes - diamonds - rare and only if another diamond has been rubbing on it.

But recutting a not so well cut diamond can get a great result.

thanks-
it''s an antique transitional cut and a family stone, so re-cutting it is out of the question. I know that the stone was in a necklace prior to being put in my engagement ring, but don''t know what it''s life was before that- it''s not "scratched" but it''s almost like the edges where the facets meet are worn- would re-polishing help with this?

I think a qualified jewellery benchperson would be able to polish diamonds. I know a cutter would.

But seriously, for something as sentimental as an old stone, I would get recommendations from people like Dave (oldminer) and Richard Sherwood who deals with antique stones. If the chip is very small, it can be polished away with minimal loss. Yes, I would say that a wee bit of polish will "sharpen" up the facet points.

Thanks for your input! I will make some calls and see what my options are!

dtnyc, I''ll be following this thread with much interest! Good luck!

For repair/recutting of a diamond, Bill Bray (aka He Scores) would be my choice...however, it seems unclear if this is your need.

It is probably a white sapphire or something other than a diamond.

Step 1 is find out if it is a diamond.

Thats the reason I would suggest checking the authenticity of the Diamond!!!

The tools and skills for polishing diamonds are rather specialized and very few jewelers do it in the store. Most of the well connected appraisers or jewelers should be able to arrange for this service if needed. That said, I’m with the above in questioning whether it’s a diamond at all. The wear you are describing is common with softer stones like Sapphire (which is darn hard on it’s own right, it’s just not a diamond). It’s not really very difficult or expensive for any gemologist to tell and you should get it checked out.

I have had it appraised, it's definitely a diamond. I had it appraised by Ted Baer in NYC and have the full report on it. It's VS2 clarity because of the chip and the natural it has and he told me about the wear on the facets. I know it's not the norm for a diamond but this is a true antique stone and I don't know the history of it before it was put on my hand.

but thanks for your health skepticism! I really appreciate it, makes a girl feel really good!

I know you know I am just a consumer but I wanted to let you know that I saw a picture in a book once, I don't have the book, showing wear on the facet edges of a very old diamond, it said. I remember thinking it looked like nothing I had seen before. All the facet edges looked whitish and ofcourse it was magnified. It was a book on antiques.

Talk with Mr. Baer about what is involved in getting it repolished. Remember to ask about any damage that may happen to the mounting during the pulling and resetting that may need to be repaired as well.
