Buying unmounted stones comes with a host of benefits, especially when they are diamonds sourced and provided by Diacore, the esteemed diamond manufacturer known for the legendary 203.04 carat De Beers Millennium Star and the CTF Pink Star, a 59.60 carat flawless Fancy Vivid Pink diamond, which sold at Sotheby’s in 2017 for a staggering $71.2 million. Through December, Sotheby’s will have regular online auctions of loose diamonds in a variety of shapes, sizes and colors, all of which present the freedom to create your own bejeweled story. Below, read our top reasons for buying loose diamonds at Sotheby’s and click here to view the latest on offer in Diamonds Online | Capsule Collection (17–24 October).
1. Shop for a Cause
In honor of Breast Cancer Awareness Month, a portion of the proceeds from Lot 1 — a group of three stunning Fancy Purplish Pink diamonds — will be donated to the Breast Cancer Research Foundation.
2. Endless Design Possibilities
Whether it is destined to be an engagement ring or a custom-designed jewel, purchasing a loose diamond allows the buyer to create his or her dream setting. At smaller weights, white diamonds are somewhat ubiquitous, therefore it is often diamonds’ subtle variations in length-to-width ratio or depth percentage that cause a buyer to fall in love with a specific stone. A preset gem may not allow such flexibility, but after finding a stone to one’s liking, virtually any design is possible with the help of a skilled jeweler.
3. Ethical Sourcing
When it comes to diamonds, provenance is everything. Because the loose diamonds in Sotheby’s online sale series are being offered straight from Diacore, which has manufacturing facilities in Botswana, South Africa, Namibia and New York, buyers know without a doubt that their stones were ethically sourced.
4. Natural Stones
The diamond is the hardest naturally occurring material on Earth, rendering it one of the most valuable and coveted gems. Especially in recent years, convincing lab-grown synthetic diamonds have flooded the market as more affordable options. Instilling confidence in all admirers and buyers, Diacore only sources natural diamonds.
5. Documentation & Certification
The Gemological Institute of America (GIA) sets the global standard for diamond certification. Each stone over 1 carat receives a certificate (“identity card”) attesting to the quality of the stone (4 Cs – color, cut, clarity and carat weight) and details its properties. All Diacore diamonds are GIA certified.
6. A Curated Mix
White diamonds come in a vast array of shapes, sizes and qualities. If the sea of options available in the global marketplace feels overwhelming, trust that Sotheby’s online auctions will provide a carefully curated and diverse selection of diamonds, all exhibiting the expert cuts, polishing and craftsmanship for which Diacore is praised.
