CERTIFIED QUALITY

Every piece of jewelry from our exclusive collections is accompanied by a certificate of authenticity, which details the characteristics defining the quality of the gemstones (the 4Cs) — cut, color, carat weight, and clarity — as well as the gold fineness, photographs and a description of the jewel, its weight, and the date of purchase.

All stated information is certified by the signature and seal of the jewelry house and by our professional gemologist with thirty years of experience in the field, who personally and meticulously selects every gemstone adorning our jewelry at verified international exchanges. Using the most advanced gemological instruments to assess the authenticity and quality of diamonds, precious, and semi-precious stones, he selects exclusively natural stones and pearls of the highest quality for you.

With every purchased jewel, we therefore include an expert statement issued by our gemological laboratory YUDC, which may also be supplemented by an international certificate from gemological institutions such as GIA, IGI, HRD, TGL, GRS, or AGL.

Our jewelry is set exclusively with natural stones, and their authenticity can be verified directly in our boutique using appropriate professional instruments. We do not work with synthetic, laboratory-grown, or treated diamonds, which guarantees absolute certainty that no substitution of a natural diamond with a laboratory-grown one — often difficult to detect — can occur during production. We strongly recommend that you carefully retain the certificate of authenticity confirming genuineness.



DIAMONDS

All diamonds, in every possible shape and size, adorning jewelry from the Diamond Spot collections are of high quality, exclusively natural and untreated, and sourced directly from prestigious diamond exchanges in Belgium and India. These diamonds are typically colorless, free from inclusions visible to the naked eye, and feature an exceptionally high cut quality. As a result, they reflect light to the maximum extent and radiate exceptional brilliance. Each diamond undergoes rigorous inspection by a gemologist to definitively exclude the presence of laboratory-grown diamonds, which have virtually no value. The certificates provided with our diamond jewelry represent expert, independent, and scientific confirmation of the diamonds’ characteristics. Every piece is accompanied by a report from our gemological laboratory YUDC and may also include a report from an international gemological institution such as GIA, IGI, or HRD.

COLORED GEMSTONES

The colored gemstones set in Diamond Spot jewelry are not subjected to treatments that artificially enhance appearance, such as laser treatment or resin filling. These interventions significantly alter the gemstones and noticeably reduce their value, unlike traditional and widely accepted methods such as oiling (for emeralds) or heat treatment (for other colored gemstones). These gentle practices have been standard in the industry for centuries. Each gemstone jewel is accompanied by a report from our gemological laboratory YUDC and may also include documentation from international gemological institutions such as GRS, GIA, IGI, HRD, TGL, or AGL. Diamond Spot also offers investment-grade sapphires, emeralds, and rubies, as well as rare gemstones. These exceptional stones are typically accompanied by reports from renowned gemological institutes such as Gübelin, GRS Platinum Award, Bellerophon, GIA, IGI, TGL, or AGL.

PEARLS

Diamond Spot also specializes in jewelry featuring Tahitian pearls sourced from French Polynesia and freshwater cultured pearls from the Chinese province of Suzhou. The Tahitian pearls adorning our jewelry, rated 10 Excellent Fine and the exceptionally high 9 Very High for luster, are remarkable for their almost perfectly round shape. They display a stunning range of black hues — from metallic gray, violet, blue, and green with silvery overtones to deep graphite — and are characterized by a very low to almost nonexistent number of inclusions. Each pearl is unique, and the subtle irregularities on its surface are proof that it is a creation of nature itself. Classic necklaces and bracelets made of freshwater cultured pearls are graded AAA and AAA+, representing very high quality, evaluated according to color, surface, luster, shape, and size. Individual pearls set in rings, earrings, and pendants are designated with the highest quality grades, AAAA and AAAA+.
