O GIA (Gemological Institute of America), uma das principais organizações mundiais na classificação gemológica, aproveita a aproximação do Dia de São Valentim, a 14 de Fevereiro, para dar alguns conselhos aos consumidores: sabem que dois carats pesam o equivalente a um clip pequeno? e que são muito raros os diamantes sem "claridades" ou completamente incolores?

CARLSBAD, Calif. – Jan. 19, 2012 – While budgeting remains a priority in the new year, consumers continue to celebrate holidays, birthdays and anniversaries with gifts of jewelry. And with around 10 percent of engagements occurring on or around Valentine’s Day, the most romantic holiday of the year sees a fair share of diamonds and colored gemstones.
Valentine’s Day has worldwide appeal, and the practice of gift giving is celebrated in Australia, Britain, China, Ghana, India, South Africa and more. In Mexico, heart-shaped and red-themed gifts appear immediately after the Christmas holiday. Japanese women bestow small gifts such as chocolate on Valentine’s Day; the men return the favor a month later on White Day by handing out jewelry and other gifts to loved ones.
GIA (Gemological Institute of America), recognized as a worldwide leader in diamonds, gemstones and pearls and the creator of the famous 4Cs (Color, Cut, Clarity and Carat weight), as well as the International Diamond Grading System™, has six tips to help consumers find their ideal piece of diamond jewelry.
Do the research: Familiarity with the 4Cs of diamond quality is a crucial element in speaking the language of diamonds. Every diamond can be described by these attributes, which when taken together, help to determine the diamond’s overall quality and value:
1. Carat: Diamonds are weighed in metric carats. Two carats weigh about the same as a small paper clip.
2. Clarity: Created by nature under tremendous heat and pressure, nearly all diamonds contain unique internal characteristics called “inclusions” and external characteristics called “blemishes.” Many clarity characteristics are too tiny to be seen by anyone other than a trained gemologist.
3. Color: Truly colorless diamonds are very rare and highly valued. GIA uses letters to represent colors, beginning with D (colorless) and ending at Z (light yellow or brown).
4. Cut: While diamonds can be fashioned into different shapes, the term “cut” refers to a diamond’s complex relationship with light. A number of factors influence a diamond’s cut grade, including its overall face-up appearance, design and craftsmanship.
A recommended starting point for learning about the 4Cs is GIA’s iPad application (app), which helps educate consumers on diamonds, and is downloadable for free on iTunes. The app is also available in Simplified Chinese.
Choose a qualified jeweler: Consumers should select a jeweler as carefully as they would a doctor, lawyer or any other trained professional. Find someone who is credentialed, such as a GIA Graduate Gemologist. Take note of their affiliations with jewelry industry groups and professional associations.
Ask for an independent diamond grading report: A diamond grading report details the gemological quality of the diamond. It tells whether the stone is natural or synthetic, if it has been treated - and how, and its quality rankings in each of the 4Cs. Verification of information contained in any GIA diamond grading report can be attained by going to Report Check, GIA’s secure online database, or by accessing it directly through the GIA 4Cs app.
Keep the purchase secure: Have the diamond appraised and insured. A diamond grading report is the independent assessment of quality; while an appraisal gives a monetary value. A personal message or the report number can be laser-inscribed on the diamond’s outer edge, called the girdle, to help identify it if it’s ever lost or stolen.
Purchase the stone loose and have the ring set later: If someone is unsure what their future fiancé prefers in a ring, one option is to purchase a loose diamond and decide on the mounting together later. Make sure to have the loose stone graded.
Consider the alternatives: Colored gemstones and pearls make unique and memorable alternatives for celebrating special occasions. With the union of the Duke and Duchess of Cambridge, and celebrities such as Penelope Cruz, Jessica Simpson and Carrie Underwood, colored gemstones are increasingly popular in the engagement ring world. Consumers should look for independent reports for colored gemstones and pearls, also available through GIA.
A gift of jewelry is an outward expression of what people mean to one another. Consumers can ensure they receive the most value for their purchase by learning more about diamonds at www.gia.edu.
