At Leandra, our jewelry is made with 18K gold , which is analyzed by the official gold laboratories.
We only use natural diamonds. Our team of gemologists chooses each stone meticulously, selecting at least F/G colour and VS purity grades. All our diamonds and other precious stones are graded according to the certification standards used by both the GIA (Gemological Institute of America) and HRD (Hoge Road voor Diamant).
The 4 Cs of diamonds:
This is the symmetry, proportioning and polish of a diamond. At Leandra we cut every stone to make it radiate light and sparkle at its best.
A carat is the unit of weight for diamonds. One carat is equal to 200 milligrams. At Leandra you can select from a range of different diamond carat weights.
Diamonds are graded from D (colourless) to Z (light yellow). Pure diamonds are perfectly transparent and colourless. At Leandra, we pay special attention to colour, which is why we guarantee all our diamonds are at least F/G.
A perfectly clear diamond, like the ones we use at Leandra, won't show any inclusions (internal defects) or blemishes (external imperfections).
Lifetime Warranty
We offer a lifetime warranty on all Leandra jewels, which includes covering any repair or replacement of defects or damages due to the production of the product.
