HRD Antwerp sealings are guaranteed secure: the certificate details on the cards inside it belong to that specific diamond. The sealing blisters are tamper proof, any attempt to open it will leave visible marks, and the sealing cannot be closed again after being opened.
Always make sure that a sealing is intact before you buy one.

From 1998 to today, the look has changed. The trust never has. Do you have HRD Antwerp sealings from before 1998? Share a photo in the comments or tag us!

Graded by HRD Antwerp | Grading jewellery gives us the opportunity to examine truly unique pieces, such as the creations of Elena Queen. Piece Unique Jewellery

Bold, creative and full of identity, each design has been graded in our laboratory with the same precision and independence behind every HRD Antwerp grading report.

From Mr. Crocky, twice nominated in Monaco and awarded third place for both the Guest Choice Award and Muse Originality, to her arachnid designs, every piece has been independently assessed. Grading confirms what the eye alone cannot: verified quality, from the metal to the stones.

Meet Ishana from Amsterdam, a graduate of our Certified Diamond Grader course in Antwerp.

Ishana decided to join the course because she is preparing to take over her family's diamond business in Antwerp, where her father works in the trade. For her, it was essential to consolidate the knowledge she already had, give it a solid technical foundation and back it with an internationally recognised diploma.

October’s Birthstones | Opal & Tourmaline

Two gemstones share October: Opal and Tourmaline. Each brings distinct optical properties and a different story.

Opal
Opal displays play of colour, a flash of spectral hues caused by light diffracting through its ordered silica spheres. With a refractive index of around 1.45 and a notable water content, it forms as a mineraloid rather than a true crystalline mineral. Ancient Romans associated it with hope and good fortune, while the Victorians linked it to love and imagination. Most precious opal originates from Australia, with Ethiopia now a significant secondary source. It sits at 5.5 to 6.5 on the Mohs scale, valued for its distinctive patterns and fire.

Tourmaline
Tourmaline is a complex borosilicate mineral occurring in nearly every colour, from deep greens and vivid pinks to the copper bearing blues of Paraíba tourmaline. Its strong pleochroism means colour can shift depending on the viewing angle, a property cutters account for when orienting the rough. Its name derives from the Sinhalese word turamali, meaning “mixed gems.” Collectors and royalty have valued it since the eighteenth century for its range of hues, including bi colour and watermelon varieties. At 7 to 7.5 on the Mohs scale, it offers both durability and colour diversity.

Which would you choose, the colour play of opal or the full spectrum of tourmaline?
