Our Diamonds & Gemstones Department specialises in fine diamonds, coloured gemstones, and carefully selected jewellery featuring exceptional stones from around the world. From classic diamond solitaires and antique-cut diamonds to sapphires, rubies, emeralds, and rare collector gemstones, we handle pieces that combine beauty, rarity, and enduring value.

Each item is professionally assessed for authenticity, quality, condition, and market desirability. Where available, accompanying certification and provenance are carefully reviewed. Detailed cataloguing provides clear information on gemstone characteristics, including cut, colour, clarity, carat weight, treatments, and setting details, giving buyers confidence and transparency throughout the auction process.

Our specialist Diamonds & Gemstones auctions attract collectors, jewellery enthusiasts, investors, and private buyers seeking exceptional stones and fine jewellery. Whether consigning a single gemstone, a treasured family heirloom, or an entire collection, we combine specialist knowledge, accurate valuation, and professional presentation to achieve strong and competitive results.
