➡️ Technical specifications

Solar Heart is one of the most unusual stones in the world of gemstones. While many gemstones derive their effect exclusively from color or brilliance, hackmanite thrives on a rare natural phenomenon: its ability to react to ultraviolet light with a distinctly altered color effect.

In daylight, the stone shows a light yellowish base tone. Under UV light, however, it develops an intense orange appearance, offering a fascinating glimpse into the special properties of this rare gemstone variety.

The heart cut gives the material additional personality. Instead of a standardized shape, a cut was chosen here that underscores the stone's individuality and enhances its visual presence.

Also characteristic are the natural growth and structural features of the material. They document the formation history of the hackmanite and give it an unmistakable identity. The visible features do not contradict the beauty of the stone, but are an integral part of its character.

At 7.45 carats, Solar Heart possesses an extraordinary size for a faceted hackmanite. Combined with its documented naturalness, its origin, and its reaction to UV light, it becomes a collector's item that goes far beyond classic gemstone concepts.

Solar Heart is aimed at collectors who appreciate rare gemstone varieties, extraordinary natural phenomena, and unique character stones.
