Welcome to Worldwide Diamond Company!

We are buyers and sellers of secondary-market diamonds and jewelry, including GIA and EGL certificated stones.

Check out our “Diamond Specials” and “Jewelry Specials” pages for the newest bargains!

We are happy to offer on your unwanted goods: simply call us at 800-764-4367 or email wwdiamond@earthlink.net.


We also offer an amazing, new color-enhancement for diamonds. Pink, yellow, blue, orange and red colors are available, at a fraction of the price of natural colors! We treat mostly secondary-market diamonds to keep the price affordable. Look at the images of loose and mounted color-enhanced diamonds, the colors are incredible.

Wholesale Only

We do not sell to the public. If you have arrived at our website and are not in the jewelry trade, we would be happy to refer you to a jeweler near you who can assist you.
