[QUOTE="Heatho, post: 398934, member: 487"] Here's a diamond flourescing under UV, only about 10% do. You can see the ones next to it have no flourescence at all. The 1ct centre stone is a cognac diamond and it has a mild flourescence. [img]https://www.prospectingaustralia.com/forum/img/member-images/487/1521673146_20170206_172247.jpg[/img] Rubies under UV. The top pic is no UV.

[img]https://www.prospectingaustralia.com/forum/img/member-images/487/1521673078_20140709_123158.jpg[/img] I did all these pics myself too. [/QUOTE]
