Buying Tips on Gems & Jewelry

Buying Essentials List
Estate Jewelry Information

1. Most Jewelry is marked up around 100% or more if you see three little keys that means the prices shown are "triple key," which means three times the wholesale price. The markup on diamonds has been squeezed by the existence of a diamond price list.

2. The "Wholesale" Diamond Price List, There is a cushion built in so that jewelers have some room for profit now that there are customers walking into stores with price lists.

3. Beauty remembers this: Diamonds are graded UPSIDE DOWN. Even people who grade diamonds for a living can't tell the color or clarity grade when the stone is right side up, which is the only way that you will ever see it once it is set in a ring. If you want to buy a better diamond, you are just investing in something that is more rare. As far as beauty is concerned, you are much better off paying for a better cut.

4. Cut Is the Most Important C because it shows brilliance and contributes with angles and proportions. The diamond quality factor that makes the most difference in the beauty of the stone is the factor that makes the least amount of difference in its price.

5. Fluorescence Costs Less (And Looks Better) which is not actually true and really does not affect the diamond's price The Gemological Institute of America did a study to test expert and non-expert opinions on diamond appearance and fluorescence. They showed diamonds with identical grades except fluorescence to a group of dealers and asked them which was better. Guess what? They can't tell the difference, except when the color of the original diamond is in the yellowish range (K and down.).

6. Size Matters, But It Goes Up In Steps Diamond pricing is based on rarity, so the bigger the diamond the more it costs per carat. The biggest step, not surprisingly, happens at 1.00 carat. People want a one carat diamond. They don't want a 0.96 carat diamond. So a 1.00 carat diamond costs a lot more per carat.

7. Some Certs are Not Worth The Paper They are Written On…DON'T ASSUME THAT ALL REPORTS HAVE THE SAME STANDARD! EGL and HRD reports have good reputations but it is odd when a diamond of a carat or more doesn't have a GIA report. GIA and AGS are the most repeatable.

8. Anyone Can Say They are a Jewelry Appraiser The other huge problem is conflict of interest. Most appraisals are done by retail jewelers. And they are selling the piece to you, judging a piece that their competition sold you, or evaluating a piece that you want to sell to them. How can they be objective?

9. Treatment the main impact of treatments on the gem diamond market is that the technology used to make diamonds can also be used to improve diamonds. Look at colored gemstones: they are almost all treated in some way and people still buy them.

10. Costs can vary in diamonds with how well the diamond is cut can make a big difference as well as how colorless and as few inclusions as possible and the carat weight.
