Refine an existing luxury heritage brand logo named AURUMTALE. Preserve the exact typography and preserve the exact geometric symbol structure. The symbol consists of four identical diamonds created from four repeated line modules with perfectly equal length, equal stroke weight, equal spacing, and strict vertical symmetry. Do not add elements, shadows, gradients, bevels, ornaments, or extra geometry. The visual power must come entirely from repetition, proportion, and symmetry. Increase symbol presence by approximately 8% relative to the wordmark. Use a sophisticated antique gold palette (#B08D57, #8A6A3B, #C8A46B) with dark bronze typography (#5A3A22). The overall impression should be timeless, prestigious, architectural, intellectual, and understated. Think HSBC, Mitsubishi, Canara Bank, Chanel, and heritage European family offices. The logo should feel as if it could remain unchanged for 50 years. Maximum simplicity. Maximum symmetry. Maximum memorability.

The image shows a brown background with the text "Aurumtale BODD5C The Sianer" written in white font. The text is centered in the middle of the image and is surrounded by a white border. The font is bold and modern, giving the logo a contemporary feel.
