Navigating the dazzling world of online jewelry stores can be both exhilarating and daunting. The abundance of choices, the plethora of designs, the divergence of price ranges, and the overall confluence of factors affecting your purchasing decision can make the process quite overwhelming. However, by asking the right questions, you can steer the process towards a rewarding conclusion that aligns with your aesthetic preferences, budgetary constraints, and ethical inclinations.

In the realm of economics, the Information Asymmetry theory proposed by George Akerlof in his seminal paper, "The Market for Lemons", postulates that in markets where sellers have more information than buyers, the latter can make suboptimal choices. This theory rings particularly true in the realm of online jewelry shopping, where the physical absence of the product can exacerbate information asymmetry. One way to mitigate this imbalance is by asking the right questions, thereby gaining essential information to make an informed decision.

First and foremost, question about the authenticity and quality of the gemstone. Utilizing the principles of Gemology, the scientific study of gemstones, delve deeper into the grade and quality of the stone. Ask about the 4Cs for diamonds, namely Cut, Clarity, Carat, and Color, developed by the Gemological Institute of America. For colored gemstones, ask about the hue, tone, and saturation. Seek information about whether the stone is natural, synthetic, or treated. This is crucial as each category has significant price implications and longevity factors.

Next, interrogate about the metal's purity. Is it 14K or 18K gold, Platinum, or Sterling Silver? The differences between them extend beyond mere pricing. They have contrasting properties, such as durability, hypoallergenic nature, and color. For instance, Platinum, due to its density and weight, is more durable and hypoallergenic than gold, but it's also more expensive.

Inquire about the manufacturing process. Is the jewelry handmade or machine-made? This question taps into the field of Operations Management and its principles. Handmade jewelry, often being more labor-intensive and involving higher levels of craftsmanship, could command a higher price compared to machine-made counterparts. However, the tradeoff is a unique piece that embodies an artisan's skill and artistry.

Probe about the return, resizing, and repair policies. The Law of Contract in most jurisdictions holds that consumers are bound by the sales contract's terms. Hence, it is crucial to understand these policies to avoid potential legal disputes and ensure smooth after-sales service.

Moreover, in line with the UN Sustainable Development Goals, ask about ethical sourcing and sustainable practices. Is the jewelry store committed to responsible sourcing? Does it use recycled metals? Are the gemstones sourced from conflict-free areas? These questions align with the growing global awareness of sustainability and social responsibility.

Finally, question about the pricing. Following Ricardo's Law of Rent from classical economics, the price of a product is based on its scarcity. Apply this principle to understand the cost of the jewelry piece. A rarer gemstone or a metal will command a higher price. Also, consider the design complexity, brand value, and market trends influencing the price.

Relinquishing the role of a mere spectator, and assuming the role of an informed inquirer can transform your online jewelry shopping experience. It can disentangle complexities, demystify jargons, and ultimately lead to a purchase that resonates with your personality, ethics, and lifestyle. After all, in the immortal words of Shakespeare, "All that glitters is not gold". So, let's ensure that what you choose is indeed 'gold' in quality, value, and ethos.
