I love my diamonds as much as the next gal but simulants can be super-useful for traveling(there's Chubb insurance of course, but the fewer claims, the better.)
More importantly for making a careful selection w/ your next diamond purchase. You get to 'live' with different shapes/carat weights/dimensions/ring designs. IME, It's smart to experiment before sinking money into diamonds that you might get sick of or find that the style/cut/size isn't your best. Unfortunately, I speak from experience... LOL. We have some $$ but not enough for anymore impulse/shaky diamond buys.
I am very lucky in as much I wear real diamonds 1.74CT eng.ring and a pair of studs at .75cts each. It took me a while of upgrading before I settled on a size for my studs, I was never brave enough to just go for this size straight off! I am currently wearing a CZ
single stone pendant ,all in silver.about a 1 carat size to 'try out' wether I want the real thing,if I don't a freind can have the CZ,if she wants it,and the whole thing cost me £20
a non bankbreaking way to road test!!! And yes,if your going on holiday,CZ replicas of your real jewellery can give you peace of mind and potentially save you a bomb in less insurance claims!
