Rolary™ Elevates Your Story: From Hair to Bespoke Diamonds
Witness the extraordinary as Rolary™ transforms your hair's carbon content into bespoke diamonds. With over 40% carbon, your hair becomes a canvas for nature's brilliance. Mirroring the Earth's mantle conditions, this process unfolds over 4-6 months at 1,600°C (2,900°F) and 66 kbar pressure.
The resulting diamond shares physical, chemical, and optical traits with natural diamonds, embodying your enduring love and milestones. From carbon to captivating gem, your hair's narrative is immortalized, reflecting the convergence of science and sentiment in a timeless masterpiece.

Step 1
We begin by extracting carbon from hair. Upon receiving your hair, it's transferred to a graphite crucible. Through a rigorous purification process, we isolate the carbon from other elements, ensuring its purity for diamond growth.
Carbon Extracting

Step 2
Once purified, the carbon is placed within a specialized machine that replicates the intense heat and pressure beneath the Earth's crust. What makes this process fascinating is that each person's carbon content is distinct, requiring a tailored combination of heat and pressure for a truly unique diamond.
