OUR POLISHED APPROACH
-
RITUAL OF CARE
Caring for your ring becomes a ritual - a gentle act of preserving its radiance. To start, mix warm water with mild dishwashing liquid, creating a solution that cradles your diamond in cleanliness. With a soft toothbrush as your companion, give your ring a delicate brush, ensuring every facet gleams with renewed vigor. Rinse it in clean water, let it rest on a cloth, and behold the sparkle.
-
EMBRACE THE SHINE
But we don't stop there – we encourage you to embrace the shine with our Scintilla Diamonds polishing cloth. It's not just a cloth; it's a gesture, a symbol of the care we put into every piece. Gently polish your ring, and as it regains its luster, know that it's not just about the sparkle but the connection you share with your precious gem.
-
MORE THAN ROUTINE
Caring for your diamond at Scintilla is more than a routine; it's a tale of love and longevity. Each sparkle tells a story of moments shared, and with our simple rituals, we ensure that your diamond becomes a timeless companion, shining brightly through the chapters of your life. So, let the ritual begin, and may your diamond always sparkle as brilliantly as the day it became a part of your story.
