Fracture filling - A part of the clarity enhanced diamond process
While the word Fracture may suggest these diamonds' integrity is compromised, these are actually just minute naturally imperfections inside the actual stone.
This process involves injecting either a bromide or a silicon wash solution that enhances the brilliancy and clarity of the diamond upgrading its natural refractive attributes, as these inclusions block light from "bouncing inside" the diamond.
The history of fracture filled diamonds
As technology advances and new materials are discovered, manipulated and engineered and adopted by gem manufacturers and so has fracture filling enhancement advanced.
This age old tradition that has moved up incredibly with every technological development, new techniques are used, like emerald oiling, recorded in the 14th century, as a way to make emeralds more appealing (Shigley, 2008).
But while diamond and emerald treatments are rather "new", research shows that the process of clarity enhancement is far more ancient. A gemological research, using infra red analysis suggest that Chinese artisans were using a wax-based material to enhance jade jewelry in Chinese artifacts as old as 2,500, found in the Hengligshan site in GuangDong, using a solution that is not very much different from the materiel used it today's jade enhancement process (Qiu et al., 2006).
While these treatments are the basis of many gem enhancement processes, they are not enough for something as beautiful as a diamond, or as intricate, rough and reflective.
Early diamond filling based on lead-bismuthate glass started appearing in the mid 80s in Israel. This process was supposedly created by Zvi Yehuda. Zvi's process included injecting a substance at high pressures (50 atmospheres) in extreme temperature (400°C). At first, it was a bit hard to identify it, but it had a few flaws that made it stick out - it's low durability, air bubbles trapped within the substance and a very distinct "flash effect": an orange-to-"electric" blue flash would appear in certain lights, as the substance's refractive index was causing shine discoloration, (Shigley, 2008). It's important to note that surface reaching fractures sometimes break light in specific angles may cause an effect that's quite similar to the "flash effect", meaning that even this side-effect, very common in older versions of the fracture filling treatments, isn't that out of place (Koivula et. al. 1989).
Due to it's organic and wholesome nature, fracture filling must be disclosed and at first, Zvi Yehuda wasn't very upfront about this process and fracture-filled diamonds were sold as untreated ones, raising much ruckus in professional circles, afraid to damage the entire field (Koivula et. al. 1989). As ethics are an important part of our belief system, unless stated differently, glogowski diamonds are clarity enhanced fracture filled diamonds, and proud of it.
It's what inside the fracture filled diamond that matters
The exact formulas are always kept secret (GIA analysts estimate that the original yehuda treatment were based on a compound of lead, chlorine, oxygen and bismuth, but the glogowski diamonds clarity enhancement process involves an advanced silicone-based solution. This solution is far less traceable and is completely invisible to the naked eye, retaining, and even enhancing, the diamond's natural refractive index (meaning it's natural ability to bend and twist light), without affecting it's color or weight.
Using cutting edge technology and the latest advancement in wash solutions, our advanced clarity enhancement procedure carries a life-time guarantee to its durability.
The Glogowski diamond's clarity enhancement process is a complete, advanced and naturally-looking procedure, guaranteeing an incredible looking diamond
