Speebs...Elizabeth and Linda are of the same mind as I have been for 25+ years of buying jewelry on island. I have some very significant pieces, and certified stones. MUCH better deals than in the US. I was even able to get my (2nd marriage) engagement ring created in SXM. Stone from one jeweler I've dealt with for years, and the setting I preferred was from another jeweler. My pieces have always been serviceable either when on island twice a year, or sent to NYC. Sometimes I don't like to go without my piece, so I suck it up and pay my Maryland jeweler for a repair or resizing. No biggie.

As has been mentioned, get your Diamond Education. Know the 5 C's. LOOK at stones in person through a loop. Also shop around on-line. Knowing clarity and color is HUGE.

Congratz, and good luck!
