A clock that shows time just like an ordinary clock. But as the needle moves from 12 pm, the clock begins to show color gradation just like in a natural diamond. It’s a special clock that has D to Z+ alphabets instead of digits from 1-12. A ‘D’ color diamond is the whitest form and shows 12 pm time. Gradually the shade changes as the needle of the clock moves further, so much so that by the time the needle completes one round, it has shown the complete diamond color gradation. It even explains the whole range of fancy color diamonds that is possible in the Z and Z+ time section of the clock.
It is particularly useful for jewellery showrooms, and diamond institutes.
