Customer Testimonial  more...

In the fall last year, I selected a semi mount and purchased a loose pink sapphire from you. I was worried the ring wouldn't be finished in time for my proposal, on my girlfriend's and my 2 year anniversary. It arrived earlier than promised and I must tell you how much my now fiance loves the ring. She loves the color and the fact that it is so unique. No one else will have a ring like hers. That makes me feel good too. I know I'll be back in a few months for a complimentary wedding band.

Diamonds - General
Diamond jewelry makes a wonderful gift for any occasion, whether it be a self-purchase just because you deserve it or a first fine jewelry gift to a sweetheart or a deeply sentimental choice to celebrate your years together. The diamonds that MyJewelrySource.com uses in our jewelry meet very strict grading standards and we are very proud of the quality, workmanship and selection we offer.  Ultimately your rings selection of diamond jewelry is based on your taste and preferences and MyJewelrySource.com offers a very wide range of styles from classic anniversary bands and eternity band rings to engagement mountings to colored diamond fashion pieces.

Amazingly, diamonds are the hardest substance known to man. They have the highest rating on the Mohs scale of hardness. They are a 10. Only a diamond can scratch another diamond. Diamonds are made of pure carbon, the only gemstone made of just one element. Interestingly, carbon is the building block that is found in every living thing on Earth. What makes diamonds so hard is their unique crystal structure, the specific arrangement of carbon atoms. Diamonds were formed millions and millions years ago when the continents were formed. Diamonds were created when just the right amount of heat and pressure were present deep inside the Earth. Blue diamonds are created when boron is present in addition to the carbon atoms. Yellow diamonds form when nitrogen is present. Diamonds have found their way to the surface through the eruption of volcanoes. Today diamonds are mined in about 25 countries, with a large percentage being mined in South Africa.

Diamonds Care

MyJewelrySource recommends cleaning your diamond jewelry with a soft-bristled brush or a cloth with plain or soapy water or jewelry cleaner.  Diamonds will become dirty and dull when they are exposed to skin oils, perfumes, lotions, dirt, and dust. These elements adhere to the surface and reduce its brilliance. So be sure to clean the underside of the diamonds since that's where most of the dirt can accumulate. While steaming and ultrasonic cleaning will not damage diamonds, these methods are not recommended by MJS as they may loosen the setting, and subsequently, stones may fall out.
