Hi, people! 
I love natural gemstones and want to design custom earrings with a couple sapphires in it.
I chose 2 blue sapphires:
http://rdagems.com/sapphires/trillion/blue/tr0006/
http://rdagems.com/sapphires/trillion/blue/tr0002/
One of those is 6.02x6.03x6.09 mm and the second is 6.48x6.46x3.62 mm
On the photos it's look like pretty similar, but dimensions is a little different.
What problems i can get in this case?
It is so hard to find a stone pair in this quality :cry:
Thanks for your answers!
