Welcome to the “Staghead Mine”! The mine is home to our hand-selected collection of ethically sourced, extremely unique, and rare gemstones. These stones were curated because they cannot be found anywhere else and possess outstanding qualities that deserve to be highlighted by truly custom rings!
Start With Your Stone!
Purchasing a stone from the mine will reserve it for you, allowing you to design the ring of your dreams around a unique stone and create a truly meaningful symbol of your love!
Shortly after purchasing, you will be emailed by one of our custom ring designers to get started on the design of your custom engagement ring. Once you have finalized your design, please note that custom commissioned rings always have the possibility of taking longer than our standard 8-week lead time. Designing and bringing a new design to life takes extra time and care to ensure the durability and quality of your custom piece.
"The Girl From Ipanema" - 3.17ct (19.3 x 8.24 x 2.75mm) Kite Cut Calico Salt and Pepper Diamond
This stone is a breathtaking kite cut that has excellent translucency and clarity. The clarity is beautifully interrupted by black and bronze inclusions. This calico diamond is ethically sourced and conflict-free.
Calico diamonds are uniquely named by Staghead Designs due to the multiple colors of inclusions. Orange and black are the primary inclusions that catch your eye in calico diamonds. These inclusions are derived from nature and are caused by nitrogen and carbon. There are other blends of opaque minerals like graphite, hematite, and pyrite that create an even more unique piece of art in your one-of-a-kind gem.
The beauty of calico diamonds is that no two are the same. What's more, these diamonds are not graded like traditional diamonds. The 4 Cs (Cut, Clarity, Color, and Carat Weight) don't come into play here. Similar to traditional diamonds, calico Diamonds also rank 10 on the Mohs scale of hardness, making them the hardest gemstone used in jewelry. If the diamond is mounted carefully and treated with care, it can last for generations!
This stone is photographed in professional studio lighting that mimics natural sunlight of 5500 degrees kelvin and videoed outdoors the same.
This stone does not display fluorescence under 365nm UV light.
For care and cleaning, we strongly recommend using soapy water and a soft brush as the safest way to clean your jewelry, avoiding ultrasonic and steam cleaners. We also suggest avoiding extreme heat as it has the potential to harm the color variation of your stone. To be safe, remove your jewelry while enjoying a soak in the hot tub or steam in the sauna! You will also want to avoid strong household chemicals and cleaners such as bleach.
**We do not reserve stones for any customer expressing interest in a particular stone. You must complete the purchase of the stone to save and reserve it for yourself! For liability reasons, we will require a signature confirmation upon delivery of your custom ring regardless of the shipping option you select at checkout.**
**Please note that when purchasing a stone, we do not send just the stone itself. In purchasing a Mine Stone, you are reserving that stone in order to work with one of our custom designers to build the perfect ring for your stone! We are artists, not stone dealers, and our passion is working alongside our clients in designing unique and beautiful rings. We love nothing more than seeing custom rings completed and a client's dreams realized!**
