<p>[QUOTE=&quot;Bronwen, post: 435167, member: 5833&quot;]Last night I did a little more playing around &amp; pulled out a small case of jewellery I had not examined with the UV light yet.&nbsp; Most things just went purple.&nbsp; Noticed the little diamond in my mother&#039;s engagement ring stayed fairly white looking.&nbsp; But then suddenly there was this little bright baby blue stone in the center of my step-grandmother&#039;s engagement ring.&nbsp; My initial reaction was that my grandfather must have been scammed, that the stone is not a diamond.&nbsp; Who knew some diamonds fluoresce, due to boron content.?&nbsp; OK, I know a few of you did.&nbsp; But it was news to me.&nbsp; Somewhere I have an appraisal for it.&nbsp; I don&#039;t recall it saying anything about fluorescence.&nbsp; Will have to find it to get an idea of whether the fluorescence is desirable or not.&nbsp; Seems it depends on the stone&#039;s 4 Cs &amp; the opinion of the particular jeweller.[/QUOTE]</p><p><br /></p>
