    Joelle, this should be useful to you....

    Hardness Scale

    Remember what your mother said, "Don't scratch"

    In 1812 the famed German mineralogist, Freidrich Mohs, devised a mineral hardness scale that is still used to measure the hardness of minerals, gems, and crystals. It's important to understand Moh's scale, which gives an idea of the relative hardness of some of the stones found in your jewelry box. By acquainting yourself with this information, you will know which stones need additional protection.

    A simple rule

    Moh's Hardness Scale is a list of 10 unique minerals. The scale arranges the minerals from the hardest to the softest. The hardest mineral, which is the diamond, is rated a No.10. The softest, which is talc, is assigned a No. 1 rating. What is interesting about Moh's findings is that the mineral that is directly above the next mineral on the scale will scratch the mineral below. So, for example, a ruby can scratch an emerald. Let's take a look at this important scale.

    Moh's Hardness Scale:

    Diamond -- 10
    Corundum (Sapphire, Ruby) -- 9
    Beryls (Topaz, Emerald, Aquamarine) -- 8
    Crystalline (Quartz, Amethyst, Opal) -- 7
    Orthoclase/Feldspar -- 6
    Apatite -- 5
    Fluorite/Fluorspar -- 4
    Calcite/Limestone -- 3
    Gypsum -- 2
    Talc -- 1



    Now you understand

    Remember Moh's Hardness Scale -- Just because a ring has a stone in it doesn't mean that it is not vulnerable to scratches. Since certain stones and minerals can scratch each other, it's important to be aware of Moh's Hardness Scale when organizing a jewelry armoire or box. Don't put your opal away right next to the sapphire ring - see how it works? Simple useful, knowledge.

    Well-crafted jewelry boxes or jewelry armoires are the perfect way to keep your valuables safe. Many have special compartments for rings or small drawers for other pieces. It's important to take the time to identify the best spot in your jewelry armoire for each piece of jewelry that you own. A simple bit of prudent care that will prolong the life of your precious stones and other jewelry.

    diamond solitaires seem more like an item on the 'must buy' list for any engagement... but i'm in 2 minds about it. firstly, its nothing special in design - all looks same from afar, also, is there any resale value? wld rather spend the $$ differently, but somehow its like one of those items that kinda 'shows the commitment of the guy to wanna marry you'.... bleah...

    hi, hoping to revive this thread..

    any brides/brides-to-be here did not buy real diamonds for your engagement/wedding rings?

    especially for those affected and concerned over "blood diamonds", what did you buy to substitute diamonds?

    Default moissanite

    i dropped by this shop selling moissanite in lucky plaza to check it out ytd.. although its sparkly, it sparkles differently from diamonds and it creates a different 'feel' too.. most of the stones are rather yellowish although i read that there are processes that can make moissanite colourless, i didn't see colourless ones in the shop =x anyone has any experience with moissanite purchases? =)
