We all love fine grade gem stones but how do you know what you are purcashing? It's hard these days to determine just who is a seller to be trusted. Here are some tips in helping avoid fraud ridden sellers.

 Read descriptions from top to bottom, some sellers will list the title as if it were a natural mined stone and then somewhere in the content of the body they will disclose that it is not, banking on the fact that most people will only look at the pictures and the title before bidding.

Check feedback! Not only the percentage but if it's anything less than 100%, go and look at what bad feedback was left and what was said. Even email the buyer who left the feedback and simply ask what happened. The last thing you want is to pay a ton of money for a fake!

Buy a meter, if you are a serious collector do yourself a favor, spend the hundred dollars and use it! They are available here on ebay from ronsrocks. Most people and even jewelry stores have no way of knowing if the stone is real or fake, the meter doesn't lie! Please do not go on blind faith, the crooks are banking on it. Don't forget to get a reflective index list as well, it will tell you what reflective index each stone is. These are available by typing the words " reflective index" into your search box, print it out and keep it with your meter.

If the seller is using a stock photo ask for them to send additional photos of the stones and remember to ask questions.

Remember that D Block isn't lightly colored material, it mainly a deep royal blue to a light navy blue with some under tones of violet. Some D Block material will have secondary red flashing and some will not, the red flashing may also appear as pink flashing which is a lesser form of red. There are sellers a out there who will label lesser grade or lighter material as D Block.

Good luck in your quest for your perfect stone!
