Blood Diamonds. Literally, Blood Diamonds.

With Valentine’s Day just around the corner, the pressure is on to find the perfect gift for that special someone. But perhaps this year, that new diamond ring may be more than just a flashy accessory. The Spanish company Algordanza has come up with a way to give turn that gemstone into more than just a symbol of your affection.

Algordanza, meaning “remembrance,” doesn’t mess around with traditional mining techniques: the creative company uses a synthetic process to convert the ashes of a lost loved one into a diamond in a Swiss lab. A mere half kilogram of your beloved’s remains are required to produce the desired effect.

After a waiting period of about six to eight weeks, the diamond is complete and can be cut to the consumer’s desired specifications. Algordanza offers the more traditional shapes, such as square-cut or pear-shaped, adding to the believability of the resulting jewel.

So while your grandmother’s antique ring may seem like a memorable gift, instead try presenting your partner with what’s left of your grandmother.
