We buy diamond jewelry at the best price

At Paraíso Jóias, we are professional, certified buyers, specializing in the appraisal and purchase of diamond jewelry. We work with items in good condition and with damaged items.

It is essential for the buyer to know the market and be recognized by it. Our experienced professionals are better equipped to present the best purchase offers.

All assessments are carried out meticulously and take into consideration the four essential denominations: Colour, Cut, Carat and Clarity.

Expert assessment

Our experts assess each diamond individually based on the 4Cs – Colour, Cut, Carat, and Clarity.

Immediate payment

Payment by cash, cheque or bank transfer after laboratory analysis.

Transparent process

The assessment process is carried out by our laboratories. After receiving the analysis, we communicate the value to the client.

Assessment criteria

The 4Cs of a diamond

All assessments take these four designations into account, which determine the real value of each stone.

Color

OK

Scale from D (colorless) to Z (light yellow). The more colorless, the higher the value. Completely colorless diamonds are the rarest and most valuable.

Cut

Lapidation

The quality of the cut determines the brilliance and luminosity of the stone. An excellent cut maximizes light reflection—it is the factor that most affects the diamond's appearance.

ct

Carat

Caratage

A measure of the diamond's weight. 1 carat = 0.2 grams. Larger diamonds are rarer, but value is not only proportional to weight — the other 3Cs also influence it.

FL

Clarity

Purity

Evaluates inclusions (internal imperfections) and blemishes (external). Scale from FL (Flawless) to I3. Diamonds without inclusions visible to the naked eye are considered clean and have higher value.
