Kobo Smith Sapporo (operated by Ippo Co., Ltd.), a specialty store for handmade wedding and engagement rings and couple's rings, with over 17,000 custom-made pieces primarily in the Hokkaido and Sapporo areas, has fully introduced 'Artificial Diamonds (Lab-Grown Diamonds)'. These diamonds are cultivated using cutting-edge technology, offering brilliance comparable to natural diamonds at a reasonable price. We propose a new diamond selection option where customers can choose and set their own diamonds into handmade engagement rings.
■ To Enable Freer and Smarter Ring Selection That Withstands Rising Prices
In recent years, with continuous price hikes and increases in the cost of precious metals and gemstones, more couples are finding themselves in a situation where they have to compromise on the size or grade of diamonds to stay within budget when choosing engagement rings.
Therefore, Kobo Smith Sapporo has added 'Lab-Grown Diamonds,' which are gaining significant attention worldwide as the standard for the next generation, to its lineup. By combining the unique experience of 'making a ring with your own hands' with the 'overwhelming cost performance and exquisite brilliance' made possible by artificial creation, we help couples overcome budget anxieties and achieve their ideal engagement ring without compromise.
■ Reliable Quality and 3 Benefits of 'Lab-Grown Diamonds' You Should Know
① Reliable Quality with International Certificates (GIA, etc.) Issued
These are completely different from ordinary 'glass or imitation stones (like cubic zirconia)'. Because they are scientifically created with the exact same composition, brilliance, and hardness as natural diamonds, they are issued with certificates from the world's most authoritative gemological institutions such as the 'GIA (Gemological Institute of America)' and 'IGI'. Their quality is officially certified, allowing you to wear them with confidence as a precious gift for a lifetime.
② Brilliance Equivalent to Natural Diamonds at a Reasonable Price (Approximately 1/10th the Price of Natural Diamonds)
Since there are no mining costs from the earth, you can choose diamonds several to nearly ten times larger or with greater brilliance for the same budget compared to natural diamonds. This allows for smart and luxurious choices, such as selecting a 'beautiful, large diamond that will take anyone's breath away at a glance, while keeping the budget around the typical price (around 300,000 yen).'
③ An 'Ethical' Choice Considering the Global Environment and Human Rights
As they do not involve large-scale mining that excavates the earth, these are 'sustainable diamonds' that do not contribute to environmental destruction, conflict, or unfair labor issues. They possess a clean beauty befitting the new start for a couple living in the coming era.
■ [Resolving Men's Concerns] Are You Aware of the 'Surprise Diamond Proposal' Option?
Many men struggle with the idea of proposing, thinking, 'I want to propose, but I don't know her finger size or preferred design,' or 'I want her to wear a design she truly likes.' The 'Surprise Diamond Proposal' offered by Kobo Smith Sapporo is designed to resolve these anxieties.
The Mechanism is Simple & Smart
First, the man visits the store alone or purchases a loose diamond online. We offer not only the currently popular, reasonably priced, and beautiful 'Lab-Grown Diamonds' but also 'Natural Diamonds.' Our knowledgeable dedicated staff will propose the optimal brilliance based on your budget and preferences. After purchase, the diamond is placed in a special proposal box, ready for the surprise proposal.
After a Successful Proposal, You Create the Ring Together
Once the proposal is successfully made, the couple can enjoy the process of handcrafting their engagement ring together, choosing the design, and then setting the diamond that was gifted during the proposal into the ring.
By leveraging the 'surprisingly low price' advantage of lab-grown diamonds, you can gift a larger and more beautiful diamond within your budget, eliminating the risk of size or design mistakes. This is the ideal proposal style for the modern era, allowing you to present your partner with both 'the ultimate brilliance' and 'the joy of choosing the design.'
