A Guide to Canadian Engagement Rings: Beauty Rooted in Ethical Sourcing and Craftsmanship
One of the primary reasons behind the surge in demand for Canadian engagement rings is the emphasis on ethical sourcing of materials. Many Canadian jewelers pride themselves on using ethically mined diamonds and other gemstones, ensuring that they are sourced responsibly and do not contribute to conflict or environmental harm. Canada has some of the strictest mining regulations globally, ensuring that diamonds are extracted in an environmentally sustainable manner and that workers are treated fairly.
Moreover, Canadian engagement rings often feature diamonds from the country's own mines, such as the renowned Ekati and Diavik mines in the Northwest Territories. These diamonds are not only conflict-free but also of exceptional quality, boasting clarity, brilliance, and fire that rival any in the world. Choosing a Canadian diamond for an engagement ring not only symbolizes commitment but also supports the local economy and upholds ethical standards.
In addition to ethical sourcing, Moissanite Engagement Rings Canada Canadian engagement rings are celebrated for their superior craftsmanship. Canadian jewelers are renowned for their attention to detail, precision, and innovation, resulting in rings that are not only breathtakingly beautiful but also built to last a lifetime. Whether it's a classic solitaire diamond ring or a more intricate design featuring intricate metalwork and accent stones, Canadian artisans pour their passion and expertise into every piece they create.
Furthermore, Canadian engagement rings often come with a personal touch, allowing couples to customize their rings according to their preferences and unique love story. From choosing the perfect diamond or gemstone to selecting the ideal setting and metal, couples have the opportunity to create a one-of-a-kind ring that perfectly symbolizes their relationship and commitment to each other.
Beyond their aesthetic appeal and ethical considerations, Canadian engagement rings also hold sentimental value for many couples. By choosing a ring crafted in Canada, couples are not only investing in a piece of jewelry but also in a piece of Canadian heritage and culture. Each ring tells a story, reflecting the natural beauty, rich history, and diverse cultures that make Canada truly unique.

Dasra Na Deepawali Lyrics
Dasara na dipawaali
Laatates gulapoli g
Saang gade saang maajha ek ukhaana
Roj nawa waate asa kon paahuna
Dasara na dipawaali
Laatates gulapoli g
Kunkawaache maajhe dhani
Yaayache g paratuni
Paawalaancha saad tyaanchya mnjulawaana
Tula pan yaawa waate kon paahuna
Ekati mi kuwaarin maajhyaakade yete kon
Kashaasaathhi ukhaanyaacha kela bahaana
Yaawa yaawa waate tula kon paahuna
Maajhyaakade yaawe kon, raamaasnge lakshman
Laajalis ka g gade, ghe tu ukhaana
Yaawa yaawa waate tula kon paahuna
Sitaamaai urmila janakaachya donhi baala
Jaawa jaawa jhaalya ale sukh udhaana
Tasa kaahi sutu paahe tujha ukhaana

More Proof Sequoia May Have >50ct Diamonds According to Arctic Star Reports and Nitrogen-Free Diamonds
50 percent of the 12 >0.3mm diamonds recovered from the Sequoia kimberlite complex in 2021 are nitrogen-free type IIa diamonds, according to analysis.
This finding supports other lines of evidence, including the diamond size distribution and diamond descriptions, suggesting this kimberlite complex has the potential to contain diamonds weighing more than 50 carats (all described as clear white).
More drilling definition is being done, which will help with future bulk sample plans that aim to recover more than 1500ct of commercial stones.
May 17th, 2022 British Columbia, Vancouver Arctic Star Exploration Corp. ("Arctic Star" or the "Company") (TSXV: ADD) (Frankfurt: 82A2) (WKN: A2DFY5) (OTC: ASDZF) is happy to announce that it has received the findings of a diamond type study based on twelve >0.3mm diameter diamonds that were recovered by caustic fusion analysis of the Sequoia Kimberlite in 2021, on its Diagras diamond property
Fourier Transform Infrared ("FTIR") Spectrometry was used to study the diamonds at the Saskatchewan Research Council Diamond laboratory in Saskatoon (an ISO/IEC 1705 Standard lab). The concentration and status of nitrogen aggregation in the diamonds are assessed using this kind of spectrometry. On the basis of the presence or absence of nitrogen impurities, diamonds are broadly classified into two types (I and II), and these types are further split into subtypes depending on the arrangement of nitrogen atoms (isolated or aggregated) and the existence of boron impurities.
According to the findings, 33% Type IaA and 17% Type IaB diamonds, 50% of the diamonds are nitrogen-free Type IIa diamonds. See Figure 1 for a pie graph illustrating the outcomes. This is in contrast to the estimated global distribution, where Type IaA diamonds predominate (96%), while Type IIa diamonds barely account for 2%.
Figure 1 shows the distribution of several diamond varieties found in Sequoia Kimberlite Caustic Fusion on the left and their estimated global distribution on the right.
Letseng-la-Terae (Letseng Mine) in the Kingdom of Lesotho and Karowe in Botswana are two of the few operating diamond mines that consistently produce Type IIa diamonds. Letseng is a modest grade (1.5-3 cpht) kimberlite, while Karowe is about (15 cpht), but both are very economic deposits since they are the most common source of big, high-value Type IIa diamonds. These kinds of diamonds are also thought to be present in the Koloa pipe, a component of the Ekati mining complex, which is located 34 kilometres west of the Sequoia kimberlite complex.
No nitrogen or boron impurities can be found in type IIa diamonds, which are typically top white colours (D, E, F, or G) or brownish hues. There are a lot of Type IIa pink and brownish-pink diamonds as well. The normal crystal structure of type IIa diamonds is anhedral, and they can have a variety of elongated, deformed, or irregular morphologies. All ten of the largest known rough diamonds recovered globally, ranging in size from the 726 carat Jonker to the 3,106 carat Cullinan, are Type IIa diamonds, which make up a major percentage of high-value, top-color, huge specialties (greater than 10.8 carats). Intriguingly, inclusion analyses reveal that the vast majority of these big stones originated from very deep layers.
Results of a study of the indicator minerals retrieved from Sequoia, which were examined and evaluated by Chuck Fipke, were made public by Arctic Star on September 9th, 2021. The >50ct big Type IIa diamonds from Leteseng, Karowe, and Ekati are coupled with unusually abundant deeply sourced indicator minerals ($DI indicators). Thus, this research anticipated the existence of Type IIa diamonds, which the FTIR has since validated.
"The presence of a significant proportion of Type IIa diamonds in the Sequoia kimberlite complex caustic fusion samples is another line of evidence of the potential to host plus 50ct, high value diamonds, backed up by the collaborative indicator chemistry and the relatively coarse, low gradient diamond size distribution," says Buddy Doyle, vice president of exploration. Since most kimberlites have a mix with a significant percentage of boart, it is odd that SRC describes all the diamonds as clean and white.
"Arctic Star is actively drilling the Sequoia kimberlite to outline its size and shape and acquire more diamonds via caustic fusion to further constrain the grade," Buddy Doyle stated. "Current advice places the grade at between 20cpht and 70cpht. The work done this year's diamonds will also be subjected to FTIR analysis. The knowledge acquired will enable the creation of a bulk sample >1500 carats, which might be retrieved in early 2023. We will be able to calculate the average value per carat, which is crucial for comprehending the economic value of this complex, after we receive the diamonds from the huge sample.

Regarding Arctic Star
In the abundant Lac De Gras kimberlite area, which is home to two multibillion dollar kimberlite mining complexes, Arctic Star is primarily a diamond explorer and has just found 5 new kimberlites there. On its Timantti property in Kuusamo, Finland, the company also holds a 958Ha Exploration permit that contains a number of diamond-bearing kimberlites. Arctic Star has granted GGL diamonds the opportunity to work on the Stein diamond property in Nunavut once the Covid restrictions are lifted. The business keeps searching for suitable diamond possibilities overseas.
